docs: Record V1.2.2 in Script A's history and add the release note
Script A: four entries under V1.2.2 for blanton_ber.sh v1.1.0 and v1.1.1, bcm_100g_dsc_cycle.sh, and tools/100G_dsc_cycle.txt; header date to 2026-09-15. CLAUDE.md: status to V1.2.2; the BER paragraph notes port 268 and the per-unit group summary; a commands block for bcm_100g_dsc_cycle.sh; the BER command block notes the three summary rows and that a zero-lane group is a failure; and a new gotcha that 'prbs get' output is data, not diagnostics. ARCHITECTURE.md: Script A ref to V1.2.2; the BER row covers port 268 and the group summary; a Key Features row for the 100G cycle test; both new files in the tree; the git tag checkbox to V1.2.2; a known issue for the unverified cycle script; and one recording that a completeness check which cannot see a failure has now bitten this repo three times - bcm_dsc_scan.sh counting its own markers, blanton_ber.sh reading lane results as shell errors, and the power-cycle report parser turning a 100% packet loss into "no data".

# v1.2.2 — The 100G uplink joins the BER sweep, and a boot cycle that can pull the power
|
||||
|
||||
## ✨ New features
|
||||
|
||||
**The BER sweep now measures port 268, the 100G uplink**
|
||||
* The port list ran `256-259` straight to `270-308`, so `ce0(268)` — the 100G uplink — was never in it. It is now its own group alongside the 200G ports.
|
||||
* The summary gives **each unit three rows**: `200G ports`, `100G p268`, and `TOTAL`. Unit 0 and unit 1 each have their own `ce0(268)`, and a marginal uplink lane averaged into 432 others is invisible; on its own row it is not.
|
||||
* A group that reports no lane at all now counts as a **failure**, not a pass. Silence on the port under test is the easiest way to ship a green report that measured nothing.
|
||||
|
||||
**Script 5 is now a boot cycle, warm or cold**
|
||||
* `5_Blanton_Script_Reboot_Cycle.ttl` → `5_Blanton_Script_Boot_Cycle.ttl`, with `EN_Cold_Warm_boot` in `config.ttl` choosing: `1` = `reboot` (warm), `2` = a cold cycle by writing the CB FPGA, `0` = neither.
|
||||
* The log file and the per-round banner are named after the kind of boot: `Blanton_Reboot_Cycle_<ts>.log` / `Reboot Cycle : N`, or `Blanton_Power_Cycle_<ts>.log` / `Power Cycle : N`.
|
||||
* Both stress logs are removed before each run. `qfx5252-stress-*` appends to its `--log` and the macro `cat`s the whole thing, so every cycle was printing back everything the earlier cycles had written — 289 lines at cycle 1 and 36,555 by cycle 199. At roughly 6.2 ms a line on a 115200 console that accounted for **+212 s of the +214 s the cycle grew** over a 199-cycle run. The DUT was never getting slower.
|
||||
|
||||
**`bcm_100g_dsc_cycle.sh` — 100G link down/up cycling with SerDes capture**
|
||||
* Tuning once, then N cycles of `port 268 en=0` → wait → `en=1` → wait → `phydiag 268 dsc` on both units → retimer `serdes-tx-get` / `serdes-rx-get` for `sys 0..7`. One log per run under `~/dsc_log/`, split by `### TEST CYCLE n/N`.
|
||||
* Waiting is a **poll of `bcmcmd ps 268`**, not `show interfaces status`. `port en=` changes the SDK, and the SONiC table only follows once gbsyncd has synced it — and this test pauses gbsyncd.
|
||||
* `-d` echoes every command as a grey `[CMD]` line before running it; `-n` is a dry run that touches nothing; the cycle count can be a bare argument (`./bcm_100g_dsc_cycle.sh 200`).
|
||||
|
||||
## 🐛 Bug fixes
|
||||
|
||||
**`blanton_ber.sh init` reported a hard error on runs that were working**
|
||||
* `[ERR ] unit 1: the BCM shell rejected 'phydiag ... prbs get'` — except the command was fine. `prbs get` prints one line per lane, a lane that has not locked says `PRBS Error!`, and the rejection check grepped the **whole** output case-insensitively for `ERROR|Invalid|...`.
|
||||
* Worse than the false alarm: the function returned early, so the lock count that was meant to judge those very lanes never ran. The operator saw an error they could not act on, and did **not** see which lanes had failed to lock. That check has been there since v1.0.0.
|
||||
* Per-lane result lines are now excluded, the match is case-sensitive, and a genuine rejection prints the offending line.
|
||||
|
||||
## 🔧 Changes
|
||||
|
||||
* **Script A takes a BER baseline before its first traffic run** (v1.2.1), so together with Script C's closing sweep the pair brackets the soak.
|
||||
* **`EN_TX_FIR`** gates the SerDes DSC scans in Script A and Script C. Default `0`: a full scan is ~10 min and both scripts do one.

|
||||
## ⚠️ Before you run
|
||||
|
||||
* **Replace `config.ttl` with the macros.** `EN_Cold_Warm_boot` is new, and Tera Term aborts on an undefined variable rather than treating it as 0.
|
||||
* **Do not run the boot cycle with `EN_Cold_Warm_boot = 0`.** Nothing reboots, the `wait "Booting in blind mode"` underneath has no timeout, and since v1.2.2 there is no `logopen` either — so it hangs *and* leaves no log showing where. `0` is the value for the A → B → C flow, where that macro is not used.
|
||||
* **The cold path writes a raw FPGA register.** `0x480` is `ICB_CTRL_REG`; the register map carries no bit definitions for it and `0xD0000` is not documented anywhere in this repo. The BDF `0000:05:00.0` is hard-coded while `blanton_fpga_pcimem.sh` auto-detects it because it moves per unit — **check the BDF on every board before running the cold path**.
|
||||
* **Anything that parses these logs must accept both banners**, `Reboot Cycle : N` and `Power Cycle : N`. A parser that greps only the first finds zero cycles in a power-cycle log and reports nothing without complaining.
|
||||
* **`bcm_100g_dsc_cycle.sh` has not been run on hardware.** It pauses `gbsyncd0/1` for tuning and unpauses them on exit, Ctrl-C included; `-P` leaves them alone.
|
||||
* **`sleep 30` and `BER_INTERVAL` now live in three places** — Script A, Script C and `blanton_ber.sh`.
|
||||
* **BER, the DSC cycle, `blanton_traffic_linespeed` and `blanton_tr518.sh` cannot overlap.** They all take the same ports.
|
||||
* **Script 4 has no teardown**: finish it with `blanton_tr518.sh stop` **and** `systemctl stop mlucas-amm`.
|
||||
* **`blanton_multiphase_margin.sh save` is permanent**, and must not be mixed with `margin.sh`.
|
||||
* **`READ_VIN` and `READ_IIN` are still not in the ADPM12200 coefficient table.**
|
||||
* **`FAN_SPEED` is 100.**
