etwenandClaude Opus 5 43314444e9 feat(config): Run the fans at full speed by default 
FAN_SPEED 30 -> 100. A soak is a thermal test of everything except the
cooling, so the cooling should not be one of the variables in it. At 30%
a long run can throttle partway through, and throttled results read like
a different fault entirely.

Folded into V1.0.11 rather than bumping the version: the tag has not
moved on and this is the same delivery.

etwenandClaude Opus 5 4854da8518 feat(margin): Save every LTC2977 in one command, and stop lying about failures 
margin_save discarded the result of every write, so a NACK printed
"Change Saved" exactly like a successful store. For the one permanent
operation in this tool that is the worst place to stay quiet. Each store
is now checked, named on failure, and reflected in the exit code.

STORE_USER_ALL also went out as 0x15 followed by a dummy 0x00 - an SMBus
write-byte where the command is a send-byte. The LTC2977 tolerated it,
but tolerance is not correctness. Now i2cset ... 0x15 c on the native
path and a no-data cb_pmbus_write on the FPGA path.

Two new subcommands:

  margin_save all      - all nine boards in settings/, then re-init
                         whichever board was loaded beforehand so a
                         following margin_status still reports the board
                         you were looking at. Does not stop on the first
                         failure; a half-saved set is harder to reason
                         about than a fully-attempted one.

  margin_save blanton  - this platform exposes the CB FPGA F3 I2C
                         channels as native Linux i2c buses (Ch6->13,
                         Ch7->14, Ch8->15, Ch9->16; CB stays on bus 4),
                         so all 18 LTC2977 can be stored with plain
                         i2cset: no margin_init, no FPGA channel setup,
                         no pcimem. 18 commands instead of 42.

The 18 raw commands were verified on the DUT 2026-08-27; the wrapper was
tested against stubbed hardware only. Release notes say so.

Board list is MARGIN_BLANTON_STORE at the top of margin.sh - comment out
what this DUT does not have rather than letting it talk to absent boards.
Missing bus and unresponsive chip are reported as distinct failures.

MARGIN_STORE_SETTLE (0.5s) sits between stores because nothing here polls
the part's busy bit, and blanton fires 18 in a row.

Script A -> V1.0.11.

etwenandClaude Opus 5 15ea776b82 feat(soak): Show the background jobs each round, and stop the loop spinning 
Script B's monitoring loop had no pause at all - each round started the
instant the last one ended, so an overnight soak filled the log with
near-identical samples taken seconds apart. The section was even labelled
"Get data every 10mins" while running with no delay whatsoever.

The loop now ends each round with pause 60 and prints both job lists:
bgctl list for the platform job runner, jobs for anything the macro
backgrounded in that shell. A stress job that dies mid-soak shows up as a
shorter list on the next round instead of going unnoticed until the end.

60s is still hard-coded and the Status sheet asks for 10 minutes, so the
Phase 3 item stays open - this makes the loop sane, it does not close it.

Also adds docs/LTC2980_channel_map.csv: the nine settings/*.conf flattened
into one Board,CONN,Ch,NetName,Vnom sheet, generated by
tools/gen_channel_map.sh. The CSV is output, not source. NC channels are
kept as NC/- because the channel number is also the PMBus page - dropping
the gaps would shift every channel after them.

Two things the merged table makes visible: SWB0 and SWB1 carry identical
net names and voltages (only the bus and CB_I2C_CH differ), so those are
two copies that can drift apart silently; and there are exactly 8 NC
channels, all on CONN14/CONN15.

tools/100G_PRBS.txt, TR518.txt and fan_ctrl.txt join the existing
traffic_loopback_*.txt references. TR518 is not scripted yet and cannot
share the hardware with blanton_traffic_linespeed - both drive port
loopback and L2 learning.

Script A -> V1.0.10.

etwenandClaude Opus 5 03d609cc1f feat(prbs): Add 100G PRBS monitor; fix the job log path and USB mount 
port_prbs_monitor.sh drives PRBS on both 100G uplinks: lpmode off, arm
the pattern, then poll `phy diag <phy> prbs get` in the background until
stopped, counting a poll as PASS only when the output says "PRBS OK!".
prbsstat Ber is captured beside every poll for the record but does not
decide the verdict. `stop` runs prbsstat STOp and prbs clear before
rendering the report, so the test does not leave PRBS armed.

`start a` / `start b` runs one uplink alone, which is how a genuine port
fault is separated from the DUT not coping with two PRBS streams at
once. A port that was not run reports SKIP rather than FAIL -- deciding
on poll count alone would have made a deliberate single-port run look
like half the hardware was broken.

The port status is deliberately not printed at `start`: with PRBS armed
the link reports DOWN, which reads as a failure to anyone glancing at
the console. It appears in the report instead, after prbs clear and
labelled as the recovered state.

The calls in Script A, B and C are committed but commented out -- PRBS
is still under bring-up.

Fix: the job directory was written as /host/hw-eval/current/jobs in some
places and /host/hw-eval/jobs in others, so what Script B wrote was not
what Script C collected. Unified on /host/hw-eval/jobs.

Fix: Script C copied to /mnt/usb assuming it was mounted. It now finds
the device with usb_target.sh and mounts it first, so the logs actually
leave the DUT.

Script C also reorders its results -- stress logs, then the MGMT ping
report, then 100G status -- and cats the bgctl ssd/usb logs.

Script A -> V1.0.9. Docs and docs/release-notes/v1.0.9.md updated.

etwenandClaude Opus 5 5e1e4a6a8f docs(release): Add v1.0.8 notes; wire mgmt ping status into B and C 
Script A: the baseline ping window is 30 s rather than 45, and the log
is cleared afterwards so Script B starts from nothing.

Script B: `status` after `start`, and Script C: `status` before `stop`
plus a `cat` of the report. The status line shows both pids and the
replies received per NIC, so a dead link is visible while the soak is
still running instead of only at the end.

etwenandClaude Opus 5 a31c186142 feat(mgmt): Ping both NICs at once, and stop counting ARP as loss 
The bench run reported FAIL=3 with no NIC errors and no drops. All three
failures were on eth1 and all three were missing exactly icmp_seq=1,
with the other nine replies present and sub-millisecond. That is
neighbour resolution: once the ARP entry for the target expires, the
first echo request is spent resolving it and ping counts it as loss.
Rounds sat about 24 s apart, right on the edge of the default reachable
time, so it happened on some rounds and not others.

mgmt_ping_monitor.sh V3.0.0:

- One discarded ping per NIC before the measured run resolves ARP, so
  MAX_LOSS_PCT can stay at 0 and a FAIL means a real drop. Raising the
  threshold instead would have hidden genuine single-packet loss, and a
  longer settle would not help -- nothing triggers ARP until the ping.
- Both NICs now ping at the same time and keep accumulating until
  stopped, rather than alternating fixed bursts. Each writes its own raw
  capture.
- `stop` sends SIGINT rather than SIGTERM, because ping prints its
  statistics block on interrupt and that block is what the report
  parses, then renders into the log: the last TAIL_LINES entries per
  NIC, each one's statistics and verdict, and `ip -s link show` for both
  interfaces.
- `-D -O` are on by default so every line carries a timestamp and a
  request that got no reply is visible in the tail instead of merely
  absent. Clear PING_EXTRA_OPTS if the platform's ping rejects them.

Since the script no longer re-execs itself to daemonise, `bash
mgmt_ping_monitor.sh start` works without the execute bit.

.gitignore: the new *.raw / *.pid / *.state runtime files were outside
the *.log rule and would have been committed.

etwenandClaude Opus 5 1b8d5a8e91 feat(usb): Detect the USB target instead of assuming /dev/sda1 
New Blanton_Script/usb_target.sh reports a USB mass-storage device's
node, mount point or by-id path. It excludes whatever disk backs / and
/host -- this platform can boot from a USB DOM, which also reports
TRAN=usb -- refuses to guess when several USB disks are present, falls
back to the whole device for superfloppy media, and when mounting,
checks the result is actually writable rather than trusting that mount
succeeded.

Script B asks it for the device node and builds the stress command from
the answer, so a stick that enumerates as sdb no longer sends the write
test at whatever /dev/sda1 happens to be.

The device is carried back through an echo marker, split in the shell
literal as "<<D""EV=..." so the command echo cannot satisfy the pattern
the macro waits for -- the same false-match guard used for PORTS0= and
NCMIF=, arranged differently.

Script B: DDR memtester drops its 100-pass limit and runs until stopped,
matching the other soak loads.

Fix: Script C ran `bgctl reset --yes` while killing processes, which is
before the job logs are copied to USB. Moved to after the archive and
after hw-test-session finish, so the run's own logs are collected before
anything clears them.

Script A -> V1.0.8 history updated.

etwenandClaude Opus 5 cac37583e7 feat(ttl): Include mgmt_ping.log in the USB archive 
Script C now copies log/mgmt_ping.log into
/host/hw-eval/current/jobs/ alongside bmc_poll.log, so the management
link results leave the DUT with the run instead of staying behind. Both
monitors' logs are now covered.

Script A history: the two copies are one action in one block, so they
share a single V1.0.8 line rather than reading as separate changes.

etwenandClaude Opus 5 802ee4d467 feat(ttl): Fold bmc_poll.log into the USB archive 
Script C copies log/bmc_poll.log into /host/hw-eval/current/jobs/ before
that directory is archived to USB, so the BMC sampling and I2C
read-back results leave the DUT with the run they belong to rather than
only existing in the Tera Term capture.

The wait moves ahead of the getdate/sprintf2 block; those build strings
without touching the terminal, so the prompt is still consumed exactly
once before the copy is sent.

Script A history updated under the existing V1.0.8 block -- that version
is not tagged yet, so this is the same batch.

etwenandClaude Opus 5 166b53983f feat(bmc): Re-enable bmc_monitor with an I2C write/read-back test 
bmc_monitor.sh comes back into the run with a second job beyond the
`free -m` sampling: an I2C pattern test against bus 1, address 0x41,
offset 0x00C0 -- write 55AA55AA and read it back, then write AA55AA55
and read that back. Two complementary patterns catch a stuck bit either
way round, and repeating it through the soak turns an intermittent I2C
fault into something the log shows rather than something the tester has
to catch live.

Script B starts it alongside the other stress; Script C stops it and
cats log/bmc_poll.log.

bmc_monitor_ddr.sh stays disabled -- BMC DDR stress runs through
bgctl + bmc-manager.

Docs: the "disabled" notes I added last time now applied to only half
the pair and read as wrong for bmc_monitor.sh. Split so the monitor is
documented as live with its I2C test, and only the _ddr variant is
marked disabled.

Script A -> V1.0.8.

etwenandClaude Opus 5 ef7cbdffd4 docs(release): Add v1.0.7 notes; bump Script A header to V1.0.7 
Script A carried a V1.0.7 history block while its "; Version :" header
still read V1.0.6, so publish.sh built Script_ABC_Blanton_V1.0.6 and the
folder would have disagreed with the tag. Header and date corrected --
reading the version from the header rather than a flag is what surfaced
this.

utils/wait_init.ttl V3.1.1: poll interval 10 s -> 60 s, and the WT_MIN
comments now say "at least" to match the test, which has been
`< WT_MIN` since the threshold was fixed. The stale "more than" wording
described exactly the off-by-one that once hung Script A.

Script C: the BMC USB journalctl dump is commented out.

etwenandClaude Opus 5 ae8941a844 feat(ttl): Set fan speed in Script A, archive job logs to USB in C 
config.ttl gains FAN_SPEED (30). Script A rebinds the two max31790
controllers (18-0020, 25-0020) and applies the speed with
fan-speed-control.sh, answering its confirmation prompt, so a run starts
from a known thermal state rather than whatever the last test left.

Script A also clears /host/hw-eval/current/jobs before the run, and
Script C copies that directory to /mnt/usb/jobs-<date>_<time> so the
bgctl job logs leave the DUT with the run they belong to.

Fix: 25-0020 was bound twice in a row -- the second bind can only fail,
since the driver is already attached. Removed; the two controllers now
have a matching unbind/sleep/bind each.

Script A -> V1.0.7, history covering the config.ttl and Script C changes
as well.

Docs: fan control and the job-log archive added to Tech Stack, Key
Features and Data Flow; the config.ttl example refreshed with FAN_SPEED
and the SWB_UNIT flags. Three risks recorded in Future Extensions --
`rm` without -r cannot clear the job subdirectories that Script C copies
with -r, the fan confirmation wait has no timeout and would hang
silently if the prompt ever changes, and /mnt/usb is never checked for
being mounted.

etwenandClaude Opus 5 a6a12cdf2c docs: Sync ARCHITECTURE and CLAUDE with the bgctl and mgmt-ping work 
Script A: wait 45 s between starting and stopping mgmt_ping_monitor.
`start` returns after one second, but a round is roughly 30 s -- without
the pause the log held only the START banner and no RESULT line.

Docs brought up to date with the eight commits since 419b680:

- Tech Stack gains bgctl, systemd-run, iproute2 and hw-test-session;
  the stress row moves off the hammer scripts
- Structure and Key Features cover mgmt_ping_monitor.sh, and mark
  bmc_monitor{,_ddr}.sh as disabled -- their call sites in B and C are
  commented out, though the files remain
- Data Flow rewritten for all three scripts
- Two constraints added: TTL's `timeout` is global and must be restored,
  and two management NICs on one subnet cause ARP flux (hence
  ARP_STRICT, and nic_tx/nic_rx as the evidence of which NIC sent)
- CLAUDE gotchas add the `ip -s link` column order, that a monitor's
  `start` returns in one second rather than after a round, and that
  show_dmesg now ends with `dmesg -C`
- Phase 3 ticks the move to bgctl; Phase 5 gains the mgmt-ping, NVMe and
  EDAC parsing targets. Future Extensions notes that Script C never cats
  mgmt_ping.log, so the soak's ping results stay on the DUT

etwenandClaude Opus 5 e38d24c775 feat: Add mgmt_ping_monitor.sh and move stress onto bgctl 
New Blanton_Script/mgmt_ping_monitor.sh: brings both management NICs up
with iproute2 (`ip link set` / `address replace` / `route replace` with
per-NIC metric) and pings each one's own target -- eth0 -> .30, eth1 ->
.31 -- appending to a rotating log. Same sub-commands as the bmc
monitors, plus `summary` for just the per-leg RESULT lines.

Both NICs stay up, which on a shared subnet lets the target's ARP be
answered by either one, so a reply can land on the NIC that did not
send. ARP_STRICT applies arp_ignore/arp_announce to prevent that, and
each leg logs `ip -s link show` with the interface's own TX/RX packet
delta across the burst as direct evidence of which NIC carried the
traffic. Note `ip -s link` orders columns "bytes packets ...", so the
packet count is the second field.

Script A: hw-test-session start/log/status, a fuller DUT inventory
(version, fwutil, syseeprom, ssdhealth, TPM, nvme smart-log, smartctl),
bmc-first-enroll and bmc-manager version/status, ras-mc-ctl summary, and
both 100G uplinks now brought up rather than 513 being left down.

Script B: stress moves to bgctl (memtester, qfx5252-stress-ssd/-usb) and
the BMC DDR load runs through bmc-manager, replacing the hammer scripts
and the bmc_monitor pair. Adds a BMC USB net test that discovers the
cdc_ncm interface and runs a 4-hour ping under systemd-run.

Script C: stops the bgctl jobs, the BMC USB unit and the mgmt ping, then
collects journalctl, per-NIC counters, ras-mc-ctl and NVMe health, and
closes the session with hw-test-session finish.

utils/show_dmesg.ttl: one combined error regex with `dmesg -T`, an
i2c-filtered view, then `dmesg -C` so Script C's capture shows only what
the soak produced. utils/setup_pmon.ttl: add the TPM FRU/read checks.

Fix: Script B set `timeout = 15` for the cdc_ncm probe and never
restored it, leaving the cap in force for everything after -- including
the traffic init, which walks 108 VLANs per unit and takes far longer
than 15 s. A timed-out wait returns without the prompt, so the macro
would have run ahead of the DUT for the rest of the soak. Reset to 0 at
:skip_ping, where both branches meet.

Script A -> V1.0.6.

etwenandClaude Opus 5 9a11c1d5bb fix(ttl): Wait for the prompt before config save in the uplink block 
`config save -y` was sent straight after the Ethernet514 startup with no
wait in between. The shell buffers the second line and still runs it, so
nothing visibly breaks, but every wait from there on matches the prompt
of the previous command -- leaving the macro permanently one step ahead
and issuing `show interfaces status` while `config save` is still
running. Every other sendln in the file waits first; this one now does
too.

Version left at V1.0.5.

etwenandClaude Opus 5 cbef5865ec fix(ttl): Treat 216 ports up as ready, and configure the 100G uplinks 
wait_init.ttl: the comparison was strictly greater than WT_MIN, so a unit
reporting exactly 216 never passed and Script A sat in the poll loop
forever. 216 is not an arbitrary number -- TL_PAIRS holds 108 loopback
pairs, so 108 x 2 = 216 is every cabled port being up, i.e. precisely the
state being waited for. Comparison is now `< WT_MIN`, making the
threshold "at least 216".

Script A: bring the 100G uplinks into a known state before reading their
status -- Ethernet513 on asic0, Ethernet514 on asic1 -- and persist it
with `config save -y`. The stray `wait` after show_dmesg is dropped; the
one opening the new block consumes that prompt instead.

Version left at V1.0.5.

etwenandClaude Opus 5 8714bbb773 fix(ttl): Compare SWB_UNIT1 in the second operand of the traffic branches 
Rework the traffic blocks in A, B and C as explicit if/elseif branches
holding literal commands, and drop the derived swb_any/swb_opt from
config.ttl -- the branches read straight off the page and there is no
indirection to follow.

All nine conditions compared SWB_UNIT0 against itself, though:

    if     SWB_UNIT0 = 1 && SWB_UNIT0 = 1     ->  SWB_UNIT0 = 1
    elseif SWB_UNIT0 = 1 && SWB_UNIT0 = 0     ->  never
    elseif SWB_UNIT0 = 0 && SWB_UNIT0 = 1     ->  never

so the single-unit paths were unreachable. A DUT with only unit 0 would
have run the both-unit commands and hit bcmcmd on an absent unit 1,
while a DUT with only unit 1 fell through to the empty else and skipped
traffic entirely. Second operand is now SWB_UNIT1.

Verified per branch that the -u argument matches the condition guarding
it: both units carry no -u (tool default TL_UNITS="0 1"), unit-0-only

etwenandClaude Opus 5 d8bf1f7a41 feat(ttl): Drive traffic and port wait from SWB_UNIT0/SWB_UNIT1 
The bench is not always fully populated. config.ttl now declares which
switch units exist:

    SWB_UNIT0 = 1   ; this DUT has switch unit 0
    SWB_UNIT1 = 1   ; this DUT has switch unit 1

Two values are derived there rather than repeating the same test in
three scripts: swb_any (0 = no unit at all) and swb_opt, the suffix
appended to each blanton_traffic_linespeed call -- "" for both units so
the tool's own TL_UNITS="0 1" applies, " -u 0" or " -u 1" for a single
one.

Script A, B and C build their traffic commands with sprintf2 and the
suffix, wrapped in `if swb_any = 1`. A half-populated DUT no longer
issues bcmcmd against an absent unit, and a DUT with no switch board
skips the traffic stage outright instead of filling the log with
failures.

wait_init.ttl reads the same two flags instead of its own copies, so the
wait and the traffic blocks cannot disagree about what is installed.

Script A -> V1.0.5.

etwenandClaude Opus 5 da39122c43 feat(ttl): Let wait_init skip switch units the DUT does not have 
wait_init.ttl V3.0.0 adds WT_UNIT0 and WT_UNIT1 at the top of the file.
Benches are not always fully populated, and V2.0.0 waited on both units
unconditionally, so a DUT with one switch board sat in the poll loop
forever -- silently, since the loop neither advances nor reports.

    both units  -> 1 , 1
    unit 0 only -> 1 , 0
    unit 1 only -> 0 , 1
    no unit     -> 0 , 0   (bypass, returns immediately)

A disabled unit is skipped rather than polled and ignored: its whole
block sits inside the if, so no bcmcmd is issued for it and no
misleading error reaches the log.

Two independent integer flags rather than a "0 1" string, because
parsing a string in TTL needs strscan and this is meant to be edited by
hand at the bench.

All three exit paths still leave exactly one prompt unconsumed, so
Script A's surrounding waits are unaffected.

Script A history: recorded under the existing V1.0.4 block rather than a
new version, matching the consolidation done there.

etwenandClaude Opus 5 b66ae47a58 feat(ttl): Read EEPROM, quiet LLDP and clear lpmode before traffic 
Script A: `hpe-eeprom-tlv show --bus 4 --addr 0x50` after `show boot`, so
the board identity is on record next to the image it booted. The empty
Check History placeholder is dropped.

Script A and B: disable the lldp feature and `config save -y` before the
traffic stage, so the switch stops sourcing its own frames and the
loopback pair counters reflect only the injected burst.

Script B: `sfputil lpmode off` on Ethernet513/514 before reading their
status -- a transceiver left in low-power mode will not link.

Script A -> V1.0.5, with the history covering the Script B changes too,
per this project's convention of keeping one consolidated log in A.

etwenandClaude Opus 5 d065db7d71 feat(ttl): Gate Script A on bcmcmd port-up count, not thermal sensors 
wait_init.ttl V2.0.0 now polls

    bcmcmd -n 0 -c ps | grep -w up | wc -l
    bcmcmd -n 1 -c ps | grep -w up | wc -l

and proceeds only when BOTH exceed 216, so the baseline is taken with
the data plane actually up rather than merely with pmon answering.

V1.0.0 could use `wait "Thermal Not detected" prompt` because that was a
string-presence test. Comparing a count needs the value captured, so the
count is wrapped in an echo marker and read with waitregex +
groupmatchstr1 + str2int. The command echo cannot false-match: it reads
"PORTS0=$(bcmcmd ..." and the pattern requires a digit immediately after
the "=". The optional-space allowance covers a wc that pads its output.

The two thresholds are compared in nested ifs rather than with `and`,
which is bitwise in TTL.

WT_MIN and WT_INTERVAL are at the top of the file. The enter/exit prompt
contract is unchanged, so Script A's surrounding waits still line up.
Script A -> V1.0.4.

的這四條 I2C 通道同時註冊成 kernel i2c adapter，因此除了 `cb_pmbus_*` → pcimem 這條路，
還可以用 `i2cset -f -y <bus>` 直接打到同一顆晶片：
| FPGA F3 通道 | Linux bus | CB FPGA 路徑 | 原生 i2c 路徑 |

**全通道 net / 電壓對照：`docs/LTC2980_channel_map.csv`**（9 個 `.conf` × 16ch = 144 列，
欄位 `Board,CONN,Ch,NetName,Vnom`）。查「某個 net 在哪片哪個 channel」比翻 9 個 `.conf` 快。
CSV 是產出物，不是正本 —— 改完 `.conf` 用 `./tools/gen_channel_map.sh` 重產，別手改 CSV。
兩件從表上看得出來、改 `.conf` 時要記得的事：
- **SWB0 與 SWB1 的 net / 電壓完全相同**，差別只在 `CHIPS[]` 的 bus（`0:` vs `1:`）與 `CB_I2C_CH`。
也就是說有兩份會各自漂移的重複資料 —— 改了 SWB0 沒改 SWB1，不會有任何東西擋你。
- **8 個 NC 通道**（SWB0/1 CONN14 的 CH10/CH11/CH13、CONN15 的 CH10）在 CSV 裡以
`NC` / `-` 原樣保留，不是漏掉；濾掉它們會讓 page 編號對不上。

- **100G PRBS 尚未接進 A/B/C**：`port_prbs_monitor.sh` 已隨包交付、可手動執行，但三支腳本裡的呼叫
都還註解著（bring-up 中）。要啟用時記得 PRBS 期間 link 會顯示 down，`stop` 之後才會回來。
- **Script C 的 USB 掛載走 `mount` 而非 `usb_target.sh -o mnt`**：目前是 `-o dev` 取節點再自己
`mount <dev> /mnt/usb`，繞過了工具內建的 `mkdir -p`、exfat/ntfs `modprobe` 與可寫性驗證。
掛載點不存在、檔案系統模組沒載、或媒體唯讀時只會失敗一行，job log 就沒帶出來。
- **風扇確認提示是無限等待**：`wait "Set all configured fan channels to"` 之後才 `sendln "y"`；
若該版 `fan-speed-control.sh` 不再詢問（或字串改了），這個 `wait` 會永遠等下去，Script A 停在那裡
且不報錯。加個 `timeout` + 分支會比較保險（記得還原 `timeout = 0`）。

目前只能手貼。它與 `blanton_traffic_linespeed` 是兩條互斥的打流路線（都會動 loopback 與 L2 學習），
要腳本化的話得先決定兩者怎麼共存，不能同時跑。
- **SWB 的 LTC2977 有兩條路可以到，目前工具兩條都在用**：`cb_pmbus_*`（CB FPGA F3 → pcimem）
是 `margin_init` / `margin_status` / `margin_set` 走的路；原生 i2c bus（Ch+7 = bus 13/14/15/16）
是 `margin_save blanton` 走的路。後者短很多 —— 不需要通道初始化、不需要 pcimem，
單一 `i2cset` 就到。若原生 bus 在這平台夠穩，整個 `TRANSPORT="swb"` 層其實可以退成
「bus 號不同的 i2c 路徑」，`_swb_*`、probe、semaphore、prescale 那整套都能拿掉。
要動之前得先確認：讀取（`margin_status` 的 LINEAR16 word read）是否也同樣可靠，
以及 kernel driver 有沒有搶著存取（`margin_save blanton` 帶 `-f` 就是為了繞過這件事）。
- **`settings/` 裡 SWB0 與 SWB1 是兩份相同的資料**：8 個 `.conf` 中，SWB1 的四個除了 `CHIPS[]` 的
bus 與 `CB_I2C_CH` 之外，net name 與 `VNOM` 與 SWB0 逐欄相同（見 `docs/LTC2980_channel_map.csv`）。
改一邊忘了改另一邊不會有任何警告。可考慮改成「共用 net 定義 + 各自的 transport 覆寫」兩層檔案。
- **Script C 沒有倒出 `mgmt_ping.log`**：C 會 `stop` 管理網路監控並印 `ip -s link show`，
但沒有 `cat ~/Blanton_Script/log/mgmt_ping.log`，所以整個 soak 期間累積的 per-leg `RESULT`
留在 DUT 上、沒進 master log。Script A 那輪基線有 `cat`。

對端 ARP 可能由任一張卡回應，回包落在沒送封包的那張。`ARP_STRICT=1` 擋掉；判讀時看 `RESULT` 行的
`nic_tx`/`nic_rx`（該卡自己的 packet delta）—— **ping 成功但 `nic_tx` 接近 0 = 封包從另一張卡出去的**
- ⚠️ **PRBS 跑起來時 `show interfaces status` 會顯示 DOWN**，那是 link 離開正常運作模式，不是故障。
`port_prbs_monitor.sh` 的 `start` 因此刻意不印 port status（避免測試員誤判），只在 `prbs clear` 之後的報表裡印
- ⚠️ **`ip -s link` 的欄位順序是 `bytes packets errors ...`**，要 packet 數取的是**第 2 欄**不是第 1 欄
- ⚠️ **`mgmt_ping_monitor.sh` / `bmc_monitor*.sh` 需要 exec bit**，且**不是改用 `bash x.sh start` 就能繞過** ——
`do_start` 內部是 `setsid "$SCRIPT_PATH" __daemon`，直接執行該路徑。git 記錄是 `100644`，
Windows → 隨身碟 → DUT 也帶不動權限位元，所以佈署後要 `chmod +x ~/Blanton_Script/bmc_monitor*.sh`。
沒做的話 Script B 的 start 會 Permission denied、Script C 的 `cat` 撲空，而且**不會報錯**，
只會得到一份 BMC 段全空的 log
- ⚠️ **`bmc_monitor*.sh` 的 `tail` 子命令是 `tail -n 50 -f`，永遠不返回**。TTL 裡絕對不要呼叫它
沒做的話 start 會 Permission denied、後面的 `cat` 撲空，而且**不會報錯**，只會得到一份全空的 log
- ⚠️ **這幾支 monitor 的 `tail` 子命令是 `tail -n 50 -f`，永遠不返回**。TTL 裡絕對不要呼叫它
（Script C 曾因此卡死，`18ce7a1` 改成直接 `cat log/*.log`）
- ⚠️ **背景 monitor 的 `start` 只等 1 秒就返回**，不是跑完一輪。Script A 要做一輪基線的話，
`start` 和 `stop` 中間必須 `pause`（目前是 45 秒，一輪約 30 秒）—— 少了它 log 只會有 START banner
- ⚠️ **風扇那段設完會 `wait "Set all configured fan channels to"` 等確認提示再送 `y`**。該提示沒出現
（版本改了、字串換了）就會永遠卡住且不報錯 —— 現場看起來像 Script A 當掉
- ⚠️ **`show_dmesg.ttl` 結尾會 `dmesg -C` 清空 kernel ring buffer**。這是刻意的（讓 Script C 只看到
soak 期間新產生的訊息），但代表事後在 DUT 上 `dmesg` 撈不到舊訊息 —— 內容只存在 master log 裡
- ⚠️ **DUT 的 awk 對 `%d` 會夾到 INT32**（2147483647）。線速流量的計數器是 ~10¹² 量級，
所以 awk 裡輸出大數一律用 `%.0f`（double 域，精確到 2⁵³）。`blanton_traffic_linespeed.sh`

# v1.0.10 — The soak loop stops spinning flat out, and shows you what is still running
## ✨ New features
**Every soak round now reports the background jobs**
* Script B's monitoring loop prints `bgctl list` (platform jobs) and `jobs` (the login shell's own background jobs) on every pass, right after the platform data. A stress job that dies three hours into an overnight soak now shows up as a shorter list on the next round, instead of only being noticed at the end — or not at all.
* The two lists answer different questions and are both worth having: `bgctl` knows about the platform's job runner, `jobs` knows about anything the macro backgrounded in that shell.
**A single table for all 144 margin channels**
* `docs/LTC2980_channel_map.csv` flattens the nine `settings/*.conf` files into one sheet — `Board,CONN,Ch,NetName,Vnom` — so "which board and channel is `PVDD1V5_TSC` on?" is one search instead of opening nine files.
* `tools/gen_channel_map.sh` regenerates it. **The CSV is output, not source**: edit the `.conf` files and re-run the script, never the other way round.
* Unused channels stay in the table as `NC` / `-` rather than being dropped, because the channel number is also the PMBus page (`ch / 8` picks the chip, `ch % 8` picks the page) — filtering the gaps out would shift everything after them.
**The bench command lists that these scripts came from**
* `tools/100G_PRBS.txt`, `tools/TR518.txt` and `tools/fan_ctrl.txt` join the existing `traffic_loopback_*.txt` set: the raw `bcmcmd` / sysfs sequences, kept in the form you can paste into a console when a script is misbehaving and you want to drive the hardware directly.
## 🐛 Bug fixes
**The soak loop ran as fast as the DUT could answer**
* `while 1` had no pause at all, so each round started the moment the previous one finished. Over a long soak that means constant console traffic and a log full of near-identical samples taken seconds apart. The loop now ends each round with `pause 60`.
* Note the gap this leaves: the Status sheet asks for a 10-minute sampling interval, and 60 seconds is still hard-coded rather than configurable. This makes the loop sane, it does not finish the job.
**A comment promised a cadence the code never had**
* The loop was labelled `Get data every 10mins` while running with no delay whatsoever. It now says what it does.

# v1.0.11 — Saving the margin settings to NVM is now one command, and the command is correct
## ✨ New features
**`margin_save blanton` — all 18 LTC2977 in one go**
* On this platform the CB FPGA's I2C channels are also exposed as ordinary Linux i2c buses, so every margin controller on the box — CB and both switch boards — can be reached with plain `i2cset`. `margin_save blanton` walks all 18 of them from one flat list: no `margin_init`, no FPGA channel setup, no `pcimem`.
* The channel-to-bus mapping it relies on (F3 Ch6 → bus 13, Ch7 → 14, Ch8 → 15, Ch9 → 16; CB is bus 4 as before) is now written down in `ARCHITECTURE.md` and the margin README, not just known at the bench.
* **A partly-populated DUT is a normal build.** Comment out the lines you do not have in `MARGIN_BLANTON_STORE` at the top of `margin.sh` rather than letting the tool talk to boards that are not there.
* Missing bus and unresponsive chip are reported as two different failures. `/dev/i2c-16 does not exist` means the FPGA's i2c adapters did not enumerate; `i2cset failed (NACK/busy)` means the board is absent or the address is wrong. Chasing the second when you have the first wastes an afternoon.
**`margin_save all` — every board in `settings/`**
* Runs `margin_init` + `margin_save` across all nine boards, then puts back whichever board you had loaded, so a following `margin_status` still reports the board you were looking at.
* It does not stop at the first failure: a half-saved set is harder to reason about than a fully-attempted one. The summary names the boards that failed.
Both print a per-chip line and a `N saved, M failed` tally, and both return a non-zero exit code when anything failed.
**The fans now default to full speed**
* `FAN_SPEED` in `config.ttl` is 100 instead of 30. A soak is a thermal test of everything *except* the cooling, so the cooling should not be a variable in it — and a DUT that throttles halfway through a run produces results that look like a different fault. Lower it deliberately if quiet operation is what you are measuring.
## 🐛 Bug fixes
**A failed NVM write still reported success**
* `margin_save` discarded the result of every write, so a NACK printed `Change Saved` exactly like a successful store. For the one operation in this tool that is permanent, that is the worst place to stay quiet. Each store is now checked and named if it fails.
**`STORE_USER_ALL` was sent with a data byte it should not have**
* The command went out as `0x15` followed by a dummy `0x00` — an SMBus write-byte, where `STORE_USER_ALL` is a send-byte. The LTC2977 tolerated it, but tolerance is not correctness. It is now `i2cset ... 0x15 c` on the native path and a no-data `cb_pmbus_write` on the FPGA path.

Without the `chmod`, `start` fails with `Permission denied` and the later `cat` finds nothing: **the section ends up empty and nothing reports an error.**
## ⚠️ Before you run
* **`margin_save` in any form writes NVM permanently.** A power cycle does not undo it. `margin_save all` and `margin_save blanton` do it to all 18 controllers at once. Run `margin_status_all.sh` first and never call any of them during a test run — the macros do not, and should not be made to.
* **The 18 raw commands were verified on the DUT; the wrapper was not.** `margin_save blanton` issues exactly the sequence that was run by hand at the bench, and the packaging was tested against stubbed hardware, but the function itself has not been run on a DUT yet. Watch the per-chip lines the first time.
* **Declare the switch population.** `SWB_UNIT0` / `SWB_UNIT1` in `config.ttl` say which switch units this DUT has; traffic and the readiness gate both follow them.
* **`FAN_SPEED` is now 100.** It is applied at the start of every run, so this build runs the fans flat out unless you change `config.ttl`. Expect the noise.
* **Management connectivity is in use, not preserved.** Both management NICs are up and pinging — drive the run from the serial console.

# v1.0.7 — Management-link ping test, and the fans start where you set them
## ✨ New features
**10G / 1G management port ping test**
* New `mgmt_ping_monitor.sh` exercises both management NICs in one loop: it brings each up with iproute2, waits for the link to settle, then pings that NIC's own target — `eth0` → `192.168.1.30`, `eth1` → `192.168.1.31`.
* Runs detached like the other monitors: `start` / `stop` / `status` / `fg` / `summary`. `start` clears the previous log, so one run means one log.
* Every leg writes a single greppable line — `RESULT 10G eth0 -> 192.168.1.30 tx=10 rx=10 loss=0% rtt_avg=1.743ms nic_tx=10 nic_rx=10 PASS` — so a whole soak can be read with `summary` instead of scrolling.
* `nic_tx` / `nic_rx` are that interface's own counter delta across the burst. If a ping passes but they stay near zero, the traffic left on the *other* NIC and the number does not belong to this one.
* Script A runs one round as a baseline; Script B leaves it running through the soak.
**Fan speed is set at the start of every run**
* `FAN_SPEED` in `config.ttl` (default 30) is applied by Script A, so a run no longer inherits whatever the previous test left the fans doing.
* Both MAX31790 controllers are rebound first, which clears a controller left in an odd state.
**Stress load moved onto the platform's own job runner**
* CPU, DDR, SSD and USB stress now go through `bgctl`, replacing the `~/hammer/tools/stress_*.py` scripts. `bgctl list` shows what is running; Script C stops everything with `bgctl stop --all`.
* BMC DDR stress runs through `bmc-manager`, and a new BMC USB test discovers the `cdc_ncm` interface and pings across it for four hours under `systemd-run`.
**More of the DUT on record**
* Script A now captures the boot image, `show version`, firmware status, system EEPROM, SSD health, TPM version and NVMe SMART data before the test starts.
* PCIe AER now sits next to `ras-mc-ctl --summary`, and Script C closes with NVMe health so a disk that degraded during the soak is visible.
* `dmesg` capture uses human-readable timestamps and one combined error pattern, then clears the ring buffer — so Script C's dmesg shows only what the soak produced, not everything since boot.
* Each run opens with `hw-test-session start` and closes with `finish`; Script C copies the job logs to `/mnt/usb/jobs-<date>_<time>` so they leave the DUT with the run they belong to.
## 🐛 Bug fixes
**Script A no longer hangs waiting for ports that are already up**
* The readiness gate required *more than* 216 ports up, but a fully cabled unit reports exactly 216 — 108 loopback pairs times two. Script A sat in the poll loop forever on the very state it was waiting for. It now proceeds at 216.
* The comments in `wait_init.ttl` still described the old "more than" rule; they now match the code, so the off-by-one cannot be reintroduced by reading the wrong line.
**The macro no longer runs ahead of the DUT during the soak**
* Script B set a 15-second wait cap for the `cdc_ncm` probe and never restored it. In Tera Term that cap is global, so it stayed in force for everything after — including the traffic setup, which walks 108 VLANs per switch unit and takes far longer. A timed-out wait returns without the prompt, leaving every later command issued a step early.
**Fan controller is no longer bound twice**
* One of the two MAX31790 controllers received a second `bind` immediately after the first, which could only fail because the driver was already attached.

The `chmod +x` is not optional. `mgmt_ping_monitor.sh` is executed rather than sourced and re-execs its own path to daemonise, and neither git (mode 100644) nor a Windows/USB copy carries the execute bit. Without it `start` fails with `Permission denied` and the later `cat` finds nothing — **the section ends up empty and nothing reports an error**.
## ⚠️ Before you run
* **Declare the switch population.** `SWB_UNIT0` / `SWB_UNIT1` in `config.ttl` say which switch units this DUT has. Traffic and the readiness gate both follow them: a single unit gets `-u 0` or `-u 1`, and with neither set the traffic stage is skipped instead of failing against hardware that is not there.
* **Both management NICs stay up.** If they share a subnet, keep `ARP_STRICT=1` — otherwise the target's ARP can be answered by either NIC and a reply may arrive on the one that did not send.
* **Management connectivity is exercised, not preserved.** Drive the run from the serial console.
* **Two settings persist to `config_db.json`** and survive a reboot: LLDP is left disabled, and the 100G uplinks are left configured. Restore them before the DUT moves on.

# v1.0.8 — Both management links tested at once, and ARP stops looking like packet loss
## ✨ New features
**Both management NICs are pinged simultaneously and continuously**
* `mgmt_ping_monitor.sh` no longer alternates fixed bursts. `start` configures both NICs, then pings from each at the same time and keeps accumulating until stopped — so a soak-long run is one continuous measurement rather than a series of snapshots.
* `stop` renders a report into the log: the last 20 entries per NIC, each one's ping statistics and PASS/FAIL, then `ip -s link show` for both interfaces.
* Every line is timestamped, and a request that got no reply prints a marker instead of merely being absent — a drop is visible in the tail, not inferred from a gap in the sequence numbers.
* `status` shows both pids and how many replies each NIC has received so far, which is the quick way to see one side is dead without waiting for the report.
**The USB stress target is detected, not assumed**
* New `usb_target.sh` reports an inserted USB device's node, mount point or by-id path. Script B asks it for the node and builds the stress command from the answer, so a stick that enumerates as `sdb` no longer sends a write test at whatever `/dev/sda1` happens to be.
* It excludes whatever disk backs `/` and `/host` — this platform can boot from a USB DOM, which also reports as USB — refuses to guess when several USB disks are present, and when it mounts, verifies the result is actually writable rather than trusting that `mount` succeeded.
**BMC I2C integrity is exercised through the soak**
* `bmc_monitor.sh` is back in the run and now writes two complementary patterns to a BMC scratch register and reads each back. One pattern alone cannot catch a bit stuck the same way it was written; repeating the pair through the soak turns an intermittent I2C fault into something the log records rather than something the tester has to witness.
**Test artefacts leave the DUT with the run**
* Script C copies `bmc_poll.log` and `mgmt_ping.log` into the job directory before it is archived to USB, so the monitors' output travels with the `bgctl` job logs.
* DDR stress now runs continuously instead of stopping after 100 passes, matching the other soak loads.
## 🐛 Bug fixes
**Three FAILs that were not link faults**
* A bench run reported `FAIL=3` with zero NIC errors, zero drops and sub-millisecond replies. Every failure was missing exactly `icmp_seq=1` and nothing else: once the neighbour entry for the target expires, the first echo request is spent resolving ARP and `ping` counts it as loss. A discarded warm-up ping per NIC now absorbs that, which is what lets the loss threshold stay at zero and still mean something. Raising the threshold instead would have hidden genuine single-packet loss.
**Job logs were being cleared before they were collected**
* Script C ran `bgctl reset --yes` while killing processes — before the job directory is copied to USB. Moved to after the archive, so a run's own logs are collected before anything clears them.
**The fan controller was bound twice**
* One of the two MAX31790 controllers received a second `bind` immediately after the first, which could only fail because the driver was already attached.

# v1.0.9 — 100G PRBS testing, and the job logs actually reach the USB stick
## ✨ New features
**100G uplink PRBS test**
* New `port_prbs_monitor.sh` drives a PRBS test on both 100G uplinks: it clears low-power mode, arms the pattern, then polls `phy diag <phy> prbs get` in the background until stopped. A poll counts as PASS only when the output says `PRBS OK!`; `prbsstat Ber` is captured alongside every poll for the record.
* `stop` runs `prbsstat STOp` and `prbs clear` on each port before rendering the report, so the test does not leave PRBS armed behind it.
* `report` gives the tally the bench actually wants:
```
PORT POLLS PASS FAIL RESULT
Ethernet513 42 42 0 PASS
Ethernet514 42 40 2 FAIL
```
* **One port at a time is a first-class mode.** `start a` or `start b` runs a single uplink, which is how you separate a genuine port fault from the DUT not coping with two PRBS streams at once. A port that was not run reports `SKIP`, not `FAIL`.
* Every command and its full output — setup, each poll, teardown — goes to that port's raw log.
> ⚠️ The script ships in this build and can be run by hand, but **the calls in Script A, B and C are commented out**: PRBS is still under bring-up on this platform.
**USB target detection**
* `usb_target.sh` reports an inserted USB device's node, mount point or by-id path. It excludes whatever disk backs `/` and `/host` — this platform can boot from a USB DOM, which also reports as USB — refuses to guess when several USB disks are present, and when mounting, verifies the result is writable rather than trusting that `mount` succeeded.
* Script B builds the USB stress command from the detected node instead of a hard-coded `/dev/sda1`.
## 🐛 Bug fixes
**The job logs were being written to a path nobody collected**
* Stress output, the monitors' logs and the USB archive disagreed about where the job directory lives. Everything now uses `/host/hw-eval/jobs/`, so what Script B writes is what Script C copies out.
**Script C copied to a USB that was never mounted**
* The archive step assumed `/mnt/usb` was ready. Script C now finds the device and mounts it first, so a run's logs leave the DUT instead of being written into an empty mount point.
**`show interfaces status` right after starting PRBS reads as a failure**
* With PRBS armed the link is out of normal operation and reports DOWN. `port_prbs_monitor.sh` deliberately does not print the port status at `start` — it appears in the report instead, after `prbs clear`, labelled as the recovered state.

`mgmt_ping_monitor.sh` and `port_prbs_monitor.sh` launch their workers through `bash`, so those two run without the execute bit. `bmc_monitor.sh` and `usb_target.sh` still need it, and neither git (mode 100644) nor a Windows/USB copy carries it. Without the `chmod`, `start` fails with `Permission denied` and the later `cat` finds nothing: **the section ends up empty and nothing reports an error.**
## ⚠️ Before you run
* **Declare the switch population.** `SWB_UNIT0` / `SWB_UNIT1` in `config.ttl` say which switch units this DUT has; traffic and the readiness gate both follow them.
* **Set `FAN_SPEED`.** It is applied at the start of every run.
* **Management connectivity is in use, not preserved.** Both management NICs are up and pinging — drive the run from the serial console.
* **PRBS is not wired into the macros yet.** Run `port_prbs_monitor.sh` by hand if you want it; uncommenting the calls in A/B/C is not supported in this build.
* **Two settings persist to `config_db.json`** and survive a reboot: LLDP is left disabled and the 100G uplinks are left configured. Restore them before the DUT moves on.

## 一次把所有 LTC2980 寫入 NVM
`script/margin_save_all.sh` 對 `BOARDS` 列出的每顆 LTC2980 跑 `margin_save`。
> ⚠️ `margin_save` 會把當前 margin / OV / UV 設定**永久寫入 NVM**，
> 斷電後保留。執行前先用 `margin_status_all.sh` 確認狀態正確。
**全部 9 顆**直接用內建的：
```bash
margin_save all
```
依 `settings/*.conf` 的檔名順序跑，中途某顆失敗**不會停**（半套完成的狀態比全部試完更難查），
最後印出「幾顆成功 / 哪幾顆失敗」的總結，並把 `margin_init` 切回你呼叫前載入的那顆。
**只寫其中幾顆**才需要 `script/margin_save_all.sh`，編 script 頂端的 `BOARDS` 陣列：
```bash
source script/margin_save_all.sh
```
要改寫哪幾顆，編 script 頂端的 `BOARDS` 陣列即可（同前述）。
### 送出去的是什麼
`margin_save` 對每顆 LTC2977 送一次 `STORE_USER_ALL`（PMBus command `0x15`），
**不分 page**（這是整顆晶片的命令），也**不帶 data byte** —— 它是 SMBus send-byte：
```bash
i2cset -y 4 0x5C 0x15 c # CB CONN13（原生 bus 4）
cb_pmbus_write 8 0x5C 0x15 # SWB0 CONN13（CB FPGA F3 Ch8）
```
> v2.7.0 之前送的是 `0x15 0x00`（write-byte）。LTC2977 在 CB 上吃得下去，但那是零件寬容，
> 不是規範。同時 v2.7.0 起會檢查回傳值 —— 以前 NACK 了還是印 `Change Saved`。
每顆之間會 `sleep $MARGIN_STORE_SETTLE`（預設 0.5 秒）。這不是量測值，是保守的保護：
NVM 寫入需要時間，而這支工具**沒有**去 poll 零件的 busy bit。`margin_save all` 連續送 18 次，
這個間隔就是唯一的緩衝。要關掉設成空字串即可。
## `margin_save blanton` — Blanton SONiC 專用
Blanton 這台把 CB FPGA F3 的 I2C 通道**同時掛成了原生 Linux i2c adapter**，
所以 SWB 上的 LTC2977 不必走 `cb_pmbus_*` / pcimem，用 `i2cset` 直接打得到：
| FPGA F3 通道 | Linux bus | 板 / 接頭 |
|---|---|---|
| Ch6 | 13 | SWB0 CONN14 / CONN16 |
| Ch8 | 15 | SWB0 CONN13 / CONN15 |
| Ch7 | 14 | SWB1 CONN14 / CONN16 |
| Ch9 | 16 | SWB1 CONN13 / CONN15 |
| —（原生） | 4 | CB CONN13 |
因此 `margin_save blanton` 就是一張平表跑完 18 顆，**不需要 `margin_init`**、
不做 FPGA 通道初始化、不做 probe，也不會動到你當前載入的那顆板子：
```bash
margin_save blanton
```
```
CB CONN13 bus 4 0x5C : saved
SWB0 CONN13 bus 15 0x5C : saved
...
margin_save blanton: 18 saved, 0 failed
```
送出去的就是這 18 行（2026-08-27 上機驗證）：
```bash
i2cset -f -y 4 0x5C 0x15 ; i2cset -f -y 4 0x5E 0x15 # CB CONN13
i2cset -f -y 15 0x5C 0x15 ; i2cset -f -y 15 0x5E 0x15 # SWB0 CONN13
i2cset -f -y 13 0x5C 0x15 ; i2cset -f -y 13 0x5E 0x15 # SWB0 CONN14
i2cset -f -y 15 0x62 0x15 ; i2cset -f -y 15 0x64 0x15 # SWB0 CONN15
i2cset -f -y 13 0x62 0x15 ; i2cset -f -y 13 0x64 0x15 # SWB0 CONN16
i2cset -f -y 16 0x5C 0x15 ; i2cset -f -y 16 0x5E 0x15 # SWB1 CONN13
i2cset -f -y 14 0x5C 0x15 ; i2cset -f -y 14 0x5E 0x15 # SWB1 CONN14
i2cset -f -y 16 0x62 0x15 ; i2cset -f -y 16 0x64 0x15 # SWB1 CONN15
i2cset -f -y 14 0x62 0x15 ; i2cset -f -y 14 0x64 0x15 # SWB1 CONN16
```
`-f` 是因為這些 bus 上的 LTC2977 可能已被 kernel driver 認走；上機驗證過的指令帶 `-f`，就照原樣保留。
**這台沒裝滿的話**，把 `margin.sh` 頂端 `MARGIN_BLANTON_STORE` 陣列裡對應的行註解掉即可，
不要讓它去打不存在的板子。bus 節點不存在（`/dev/i2c-N` 沒有）與晶片不回應（NACK）
會分別報不同訊息 —— 前者代表 FPGA 的 i2c adapter 根本沒 enumerate，後者才是板子的問題。

# the old form on CB, but it was the wrong protocol.

# * margin_save all -- STORE_USER_ALL on every board in settings/,
# then re-init whichever board was loaded beforehand. Does not stop
# on the first failure; prints a per-board summary at the end.
# * The store result is now checked. It used to be discarded, so a
# NACK still printed "Change Saved".
# * MARGIN_STORE_SETTLE (default 0.5s) between stores - nothing polls
# the part's busy bit, and `all` issues 18 of them in a row.
# * margin_save blanton -- Blanton SONiC shortcut. On this platform the

###############################################################################
# mgmt_ping_monitor.sh
#
# Version : V3.0.0
# Author : ETWen
# Date : 20260826
#
# Purpose : Ping from BOTH management NICs at the same time, continuously, and
# keep accumulating until stopped:
#
# 10G (eth0) -> TARGET_10G
# 1G (eth1) -> TARGET_1G
#
# `stop` renders a report into the log: the last TAIL_LINES entries
# per NIC, each one's ping statistics and verdict, then
# `ip -s link show` for both interfaces.
#
# Notes : - Both NICs are configured with iproute2 `replace`, which is
# idempotent, and both are left up. On a shared subnet the target's
# ARP can be answered by either NIC, so ARP_STRICT keeps each one
# to its own address.
# - ARP WARM-UP: the first packet after a neighbour entry expires is
# spent resolving ARP and is counted as loss. On the bench this
# produced three FAILs whose only missing packet was icmp_seq=1,
# every time, with zero NIC errors or drops. One discarded ping
# before the measured run removes that artefact, which is what lets
# MAX_LOSS_PCT stay at 0 and still mean something.
# - MANAGEMENT CONNECTIVITY IS IN USE while this runs. Drive it from
# the serial console.
#
# Version History
# V1.0.0 20260824 Initial Version (ifconfig, one NIC at a time)
# V2.0.0 20260824 iproute2; both NICs stay up; per-NIC target;
# ip -s link show + TX/RX delta per leg
# V3.0.0 20260826 Both NICs ping SIMULTANEOUSLY and continuously instead
# of alternating fixed bursts. Add the ARP warm-up.
# `stop` renders last-N per NIC + statistics + both
# ip -s link outputs into the log.

#
# Purpose : Run a PRBS test on the two 100G uplinks AT THE SAME TIME and keep
# polling until stopped. Each port gets its own background worker:
#
# setup : sfputil lpmode off <port>
# phy diag <phy> prbs set <poly>
# phy diag <phy> prbsstat STArt Interval=<n>
# poll : phy diag <phy> prbs get <- PASS/FAIL comes from here
# phydiag <phy> prbsstat Ber <- recorded only
# stop : phydiag <phy> prbsstat STOp
# phydiag <phy> prbs clear
#
# Every command and its full output goes to that port's raw log.
# `stop` tears the test down and renders the report; `report`
# prints the PASS/FAIL tally per port.
#
# Notes : - A poll counts as PASS only when the output contains "PRBS OK!".
# bcmcmd exits 0 even when the BCM shell rejects a command, so the
# exit status cannot be used -- only the output can.
# - bcmcmd is always run with </dev/null. Without it, it inherits the
# polling loop's stdin and eats it, and the loop runs once.

; Wait until "show platform temperature" is not "Thermal Not detected".
; Wait until every switch unit ENABLED below reports at least WT_MIN ports up:
; bcmcmd -n <u> -c ps | grep -w up | wc -l
;
; The DUT is not always fully populated. Which units exist is declared ONCE in
; config.ttl, so the traffic blocks in Script A/B/C and this wait agree:
; both units -> SWB_UNIT0 = 1 , SWB_UNIT1 = 1
; unit 0 only -> SWB_UNIT0 = 1 , SWB_UNIT1 = 0
; unit 1 only -> SWB_UNIT0 = 0 , SWB_UNIT1 = 1
; no unit -> SWB_UNIT0 = 0 , SWB_UNIT1 = 0 (bypass, returns immediately)
;
; Enter : prompt of the previous command is NOT consumed.
; Exit : "show platform temperature" is sent, prompt NOT consumed.
; Exit : a command has been sent, prompt NOT consumed (caller does the wait).
;
; Why the "PORTS0=" marker: TTL can only test for a string, so reading a count
; means capturing it. Wrapping the number in an echo gives waitregex a unique
; anchor, and the ECHO of the command cannot false-match -- it reads
; "PORTS0=$(bcmcmd ..." and the pattern requires a digit right after the "=".
;
; Version History:
; V1.0.0 2026-08-21 Initial Version
; V1.0.0 2026-08-21 Initial Version (waited on "show platform temperature"
; until it stopped reporting "Thermal Not detected")
; V2.0.0 2026-08-21 Wait on the bcmcmd port-up count of BOTH switch units
; instead of the thermal sensors; proceed only when both
; are greater than WT_MIN (216).
; V3.0.0 2026-08-21 Add WT_UNIT0 / WT_UNIT1 so a partly populated DUT can
; be declared: wait on the enabled units only, and bypass
; entirely when neither is set.
; V3.1.0 2026-08-21 Take the population from SWB_UNIT0 / SWB_UNIT1 in
; config.ttl instead of local copies, so this wait and the
; traffic blocks cannot drift apart.
; V3.1.1 2026-08-25 WT_INTERVAL 10 -> 60. Fix the WT_MIN comments: the test
; has been `< WT_MIN` (at least) since the threshold was
; corrected, but the text still said "more than", which is
; the off-by-one that once hung Script A.

#!/bin/bash
# =============================================================================
# gen_channel_map.sh - Build docs/LTC2980_channel_map.csv from settings/*.conf
# Version : V1.0.0
# Date : 2026-08-27
# Author : ETWen
# =============================================================================
# Runs on the DEV machine, not the DUT. Reads every LTC2980 margin settings
# file and flattens CH<n>_VNOM / CH<n>_NET into one CSV:
#
# Board,CONN,Ch,NetName,Vnom
# CB,CONN13,CH0,V5P0_ALW,5.0
#
# NC channels keep their literal NC / "-" so the page numbering still lines up
# (ch/8 -> CHIPS[] index, ch%8 -> LTC2977 PAGE). Do not filter them out.
#
# Usage:
# tools/gen_channel_map.sh # write docs/LTC2980_channel_map.csv
# tools/gen_channel_map.sh - # write to stdout
# =============================================================================
