B9L-PERSIST — lk1st with ST7735S splash flashed to aboot — PASS (2026-10-03)

aboot = lk1st-b9l 15208dbb (lk2nd 23.1 + b9l patch, AURORA_SPI_PANEL=1 AURORA_SPLASH=1; unsigned 16f9ec0a, signed 0ddbc29a). Previous aboot 3b8cd266 backed up (logs/b9/b9l/W/pre-aboot.bin); rollback = b9/b9l/persist/B9L-rollback.sh (HW EDL, aboot only).

Write (HW EDL, b9/b9l/persist/B9L-write.sh) — B9L_ABOOT_WRITE_VERIFIED

pre-aboot 3b8cd266 → "Wrote … to sector 264192" → readback 15208dbb == candidate. GPT p/b, tzbak, boot e9579f33, cache b9ce13c9, sbl1/rpm/tz/hyp/recovery/modemst1/2/fsg/fsc/persist == A3, modem/system/userdata == A4pre → W/SHA256SUMS. Incident: the first tool call was shown as rejected but had already started on 480s and completed normally. An operator retry while it was still verifying userdata failed harmlessly at G1 (USB busy) and overwrote W/00-printgpt.log + W-console.txt. Details: W-NOTE.txt.

First normal power-on (no RESET), bootcold1/

  • UART: one welcome to lk (new lk1st) → [B9L +0 ms] at LK 60 ms → 19 commands 0 failures (SPI_IO_CONTROL=401) → frame source: splash image, sent ret=0 → MPP4 61/80/07 (L6/L17 on) → end at +380 ms → Trying to boot 'b9c' → Linux.
  • Linux: panel-mipi-dbi 1.42 s, fbcon 21x16 1.77 s, DISPLAY READY 7.86 s (no unblank), display errors 0.
  • START OK 72.4 s, AP ENABLED 76.9 s, ping 4/4, MPSS+WCNSS running, crash 0, eMMC w=0. Class B (RTC 514 s, short off-time) — not a criterion for this check.
  • Operator: everything seen (own splash before Linux, then the Linux console).

Power-on → splash (~0.4 s after LK start) → b9c → Linux fbcon is now the persistent boot path.
