  v1.1.3 — Margin now measures against what this platform actually runs at Stable

  etwen released this 2026-08-30 22:13:48 +08:00 | 21 commits to main since this release

  ✨ New features

  Per-CONN margin profiles for the switch boards

  • combo_SWB_CONN13_high / _low through combo_SWB_CONN16_high / _low replace the old comboA / comboB pair. Each file's per-channel percentages follow the rails on that board, so a CONN13 profile is no longer a rough fit for CONN16.
  • SWB0 and SWB1 share a profile per CONN — the two boards carry identical rails and differ only by I2C bus.
  • A high pass and a low pass are now the same run with _high swapped for _low.
  • A profile applied to the wrong CONN margins the wrong rails and says nothing. The percentages are positional, so nothing detects the mismatch. margin_apply_profile_all.sh now names the right profile per board instead of one name for all nine.

  🐛 Bug fixes

  VNOM was the spec value, not what the rails actually sit at

  • 86 of the 144 channels moved up between +0.8% and +2.5% to the measured median for this platform — PVDD3_3V_SYNTH_LDO_* 3.3 → 3.38, P0V9_AVDD_* 0.9 → 0.915, PVDD0_8V_T3 0.8 → 0.82, and so on.
  • This is not a display change. VNOM is the denominator of margin_status's deviation %, and the basis margin_set derives high / low / OV / UV from. A rail sitting steady at 0.756 V used to read +0.80% against a nominal 0.75 and now reads 0.00%; and asking for +3% now lands on a different absolute voltage than it did last week.
  • Margin logs from before and after this build cannot be compared directly. The numbers moved because the reference moved, not because the hardware did.

  The batch profile script pointed at files that no longer exist

  • margin_apply_profile_all.sh still named comboA for all nine boards. With comboA.conf removed, every board would have stopped at Profile not found — a nine-line wall of errors on a script that is normally left to run.

  The channel map CSV was stale

  • docs/LTC2980_channel_map.csv is generated from settings/*.conf, so all 86 changed rails were wrong in it. Regenerated with tools/gen_channel_map.sh. It is output, not source — regenerate it, never hand-edit it.

  Script_ABC_Blanton_V1.1.3.zip	The full Tera Term working directory, including Blanton_Script/ to copy onto the DUT

  After copying to the DUT:

  chmod +x ~/Blanton_Script/*.sh      # see below
  grep -rlU $'\r' ~/Blanton_Script    # expect no output
  

  blanton_ber.sh and nfc_polling.sh are invoked by the macros through ./ or ~/, so they need the execute bit along with bmc_monitor.sh and usb_target.sh — neither git nor a Windows/USB copy carries it reliably.

  ⚠️ Before you run

  • Re-baseline your margin expectations. Any pass/fail limits or golden logs derived from the old VNOM values need redoing against this build.
  • margin_save in any form writes NVM permanently and now writes margin windows derived from the new reference. Run margin_status_all.sh first and never call it during a test.
  • SWB profiles are per-CONN. Applying combo_SWB_CONN13_high to a CONN16 board is silently wrong.
  • These three tests cannot share the switch: blanton_ber.sh, blanton_tr518.sh and blanton_traffic_linespeed.
  • PRBS takes the links down while blanton_ber.sh is armed.
  • ce0 keeps running until you stop it.
  • Two numbers must stay in step: Script C's sleep 30 and blanton_ber.sh's BER_INTERVAL.
  • FAN_SPEED is 100 — the fans run flat out unless you change config.ttl.
  • nfc_polling.sh start clears the log, so Script B wipes Script A's NFC baseline file (the numbers are already in the console log).
  • The NFC tool is written for the customer's tag. It polls Type A / B / F only and parses Type A strictly; a tag of another technology is never discovered and fails as no RF interface activation notification received. Without --expected-id it does not check identity, so a different tag of the same type still passes.
  • The three items listed as unverified in v1.1.0 are still unverified: the ce0 ingress mirror, the 120s settle in blanton_tr518.sh, and test mode nr=no on stop.
