+# v1.2.5 — Switch-board rail power in every snapshot, a raw BER run, and tools to turn off unused lanes
+
+## ✨ New features
+
+**PMON snapshots now carry the switch-board rail power**
+* `utils/setup_pmon.ttl` calls `TH6_SWB0_power_readback.sh` and `TH6_SWB1_power_readback.sh` right after `show platform current` — the 19 rails of each switch board with V × I and a `TOTAL POWER` line.
+* `setup_pmon` is shared, so this lands in Script A, B, C, 4 and 5 alike.
+
+**`blanton_ber_debug.sh` — the hand-run BER flow as one command**
+* Runs exactly what `tools/BER_Test.txt` does: `prbs set p=p31` → `prbs get` twice → `prbsstat STArt Interval=30` → `sleep 40` → `prbsstat Ber` → `STOp` → `prbs clear`.
+* Every `bcmcmd` output is printed **as is**, under a `### [time] unit N: ...` header — no parsing, no PASS/FAIL, no summary. For looking at the raw output on the bench; `blanton_ber.sh` remains the judged version.
+* `-u 0` / `-u 1` for one switch unit; both by default. `BER_POLY`, `BER_INTERVAL`, `BER_WAIT` and `BER_PORTS` can be overridden from the environment.
+
+**`retimer_lanes.sh` / `unused_lanes.sh` — turn off TX on lanes nothing is cabled to**
+* `retimer_lanes.sh <asic> <addr> <lane_map> <off|on|status>` acts on one Agera3 retimer, sys **and** line side. `--method squelch` (default, TX squelch, lanes stay powered) or `--method power` (TX+RX power-down, needs an `agera3` that has the `power` command). It reads the state back afterwards and prints `PASS` / `FAIL`.
+* `unused_lanes.sh <off|on|status>` applies that to a built-in table — 14 retimer rows and one direct-TH6 row (TSC31, `cd112-cd115`) — on both switch boards. `--asic 0|1|all`, `--th6` to also disable the TH6 ports behind the retimer rows, `--only <target>` for a single row. Ends with `ok / refused / failed` counts.
+* **`off` is refused on a lane that receives a signal** (RX PMD lock, or link up on a TH6 port) unless `--force` is given.
+
+**`5_1_Blanton_Script_Boot_Cycle_Fast.ttl` — the boot cycle without the traffic run (standalone)**
+* Identical to Script 5, except Check Pt8 only runs `blanton_traffic_linespeed ps` — no `init` / `start` / 15 s / `stop` / `report`. A shorter cycle when the point is the number of boots.
+
+**Boot cycle shows its count in the window title**
+* Script 5 and 5_1 set the Tera Term title to `Reboot Cycle Test : n` or `Power Cycle Test : n` each round.
+
+## 🐛 Bug fixes
+
+**`qfx5252-stress-usb` now runs with `--force`** in Script B and in the boot cycles.
+
+## 📦 Downloads

+grep -rlU $'\r' ~/Blanton_Script    # expect no output
+```
+
+## ⚠️ Before you run
+
+* **`chmod +x` after deploying.** The power readbacks are called by path from every PMON snapshot, and `unused_lanes.sh` refuses to start unless `retimer_lanes.sh` next to it is executable.
+* **Script 4 now reads the switch-board power twice per round** — once inside `setup_pmon`, once from its own loop. Harmless, but the log carries both.
+* **`blanton_ber_debug.sh` uses `p=p31` (verified on the bench); `blanton_ber.sh`, and so Script A / C, still sets `p=3`.** The two may not be measuring the same pattern — do not compare their BER directly until that is settled.
+* **`blanton_ber_debug.sh` leaves out port 268**, the same list as `BER_Test.txt`. Add it with `BER_PORTS="...,268"`.
+* **`EN_Cold_Warm_boot = 0` (the `config.ttl` default) hangs Script 5 and 5_1.** Set it to `1` (reboot) or `2` (power cycle).
+* **Script 5 and 5_1 are two copies of the same macro** — a fix to one has to be made to the other.
+* **Script 4 has no teardown**: finish it with `blanton_tr518.sh stop` **and** `systemctl stop mlucas-amm`.
+* **`FAN_SPEED` is 100.**

+# v1.2.6 — FDR statistics around the traffic run, and unused lanes turned off before the baseline
+
+## ✨ New features
+
+**`blanton_fdr.sh` — FDR statistics through `phydiag fdrstat`**
+* Four sub-commands, each run on unit 0 then unit 1, over ports `'1-259,270-565'`:
+  `start` (`fdrstat STArt bin_group=both Interval=30`), `clear` (`fdrstat clear`), `rdcnt` (`fdrstat Counters`), `stop` (`fdrstat STOp`).
+* Output is printed as is, under a `### [time] unit N: ...` header — no parsing, no PASS/FAIL.
+* `-u 0` / `-u 1` for one switch unit, `-i <sec>` for the interval, `-n` for a dry run. `FDR_PORTS` overrides the port list.
+
+**FDR runs alongside the traffic test in Script A, B and C**
+* **Script A** wraps its traffic baseline: `fdr start` after `init`, `fdr clear` after `clear`, `fdr rdcnt` after the run, `fdr stop` after the traffic stop. The traffic run is now **40 s instead of 15 s**, so the counters are read after the first 30 s interval has been published — the same rule as `prbsstat Ber`.
+* **Script B** starts and clears FDR with the traffic setup, before the soak loop — the counters run for the whole soak — and reads them (`rdcnt`) in every soak round, after the Tray ID stress.
+* **Script C** reads them (`rdcnt`) before stopping the traffic and stops FDR after it — the closing read of the counters Script B started.
+
+**Script A turns off the unused lanes before the BER baseline**
+* `unused_lanes.sh off` — TX squelch on the unused retimer lanes and TSC31 (`cd112-cd115`) disabled on the TH6, on both switch boards.

+
+## ⚠️ Before you run
+
+* **`chmod +x` after deploying.** `blanton_fdr.sh`, `unused_lanes.sh` and `retimer_lanes.sh` are all called by path; `unused_lanes.sh` also refuses to start if `retimer_lanes.sh` is not executable.
+* **`blanton_fdr.sh stop` sends `fdrstat STOp` — that keyword is inferred from `prbsstat STOp` and has not been checked on the bench.** `bcmcmd` exits 0 even when the BCM shell rejects a command, so if it is wrong, FDR keeps running and only the log shows it. Check the first run.
+* **FDR only runs when both switch units are enabled** (`SWB_UNIT0 = SWB_UNIT1 = 1`). The single-unit branches have no FDR, and Script A's single-unit traffic run is still 15 s.
+* **Script B's per-round `fdr rdcnt` is not gated by the unit settings** — with one unit enabled, FDR was never started and each round just logs whatever `fdrstat Counters` returns.
+* **Nothing turns the unused lanes back on.** Script C has no `unused_lanes.sh on`; run it by hand when the DUT is needed in its normal state. Whether a reboot clears it has not been checked.
+* **`unused_lanes.sh off` is not gated by `SWB_UNIT0` / `SWB_UNIT1`** — it always acts on both boards.
+* **`blanton_ber.sh` (Script A / C) still uses `p=3` and `sleep 30`**; see v1.2.5.
+* **Script 4 has no teardown**: finish it with `blanton_tr518.sh stop` **and** `systemctl stop mlucas-amm`.
+* **`FAN_SPEED` is 100.**

+# v1.2.7 — FDR on the cabled ports only, and the vendor NFC tool updated to v2.5
+
+## 🐛 Bug fixes
+
+**`blanton_fdr.sh` no longer prints the uncabled ports** (v1.0.1)
+* The default port list was `'1-259,270-565'`, which also covered ports nothing is cabled to (cd15..19, cd47..51, cd111..115, ...).
+* It is now the cabled-port list from `blanton_traffic_linespeed.sh` (`TL_PS_PORTS`), the same one `blanton_ber_debug.sh` uses:
+  `1-24,40-96,112-168,184-240,256-259,270-308,310-327,342-380,382-399,414-452,454-471,486-524,526-543,558-565`.
+* Script A, B and C pick this up with no change to the TTLs.
+
+## 📦 Vendor tool update
+
+**`blantons_nfc_validate.py` v2.3 → v2.5** — the customer's `qfx5252-nfc-validate`, renamed to keep the name `nfc_polling.sh` calls.
+* New: `--read-ndef` (Type 2 / Type 4 NDEF, Text and AMD FRU records), `--write-ndef` / `--set-location`, `--max-ndef-bytes`; NCI data packets with credit flow control.
+* Fixed: a `FileNotFoundError` crash while listing the processes that hold the NFC device open.
+* Bad arguments now print `[FAIL]` and exit 1 — `nfc_polling.sh` counts that as **FAIL**, not ERROR.
+* The default `test --debug` output (`[PASS]` / `[FAIL]` lines, `NFCID1=`) is unchanged, so `nfc_polling.sh` is not modified.

+```
+
+## ⚠️ Before you run
+
+* **Port 268 (ce0, 100G uplink) is not in the FDR list** — as before. Add it with `FDR_PORTS="...,268"` if FDR is wanted there.
+* **The cabled-port list now lives in three scripts** — `blanton_traffic_linespeed.sh`, `blanton_ber_debug.sh`, `blanton_fdr.sh`. Change all three when the cabling changes.
+* **Never put the NFC write flags (`--write-ndef`, `--set-location`, `--confirm-write`) in `NFC_ARGS`** — polling would rewrite the tag every round.
+* **`blanton_fdr.sh stop` (`fdrstat STOp`) is still unverified on the bench**; see v1.2.6.
+* **Nothing turns the unused lanes back on**; run `unused_lanes.sh on` by hand. See v1.2.6.
+* **`blanton_ber.sh` (Script A / C) still uses `p=3` and `sleep 30`**; see v1.2.5.
+* **Script 4 has no teardown**: finish it with `blanton_tr518.sh stop` **and** `systemctl stop mlucas-amm`.
+* **`FAN_SPEED` is 100.**
