- final persistent validation (cold2): autonomous class-A boot from cache c3732515, live cache hash re-read,
CHARGING/FAST, USB remove/insert recovery, LTE/Wi-Fi/NCM/display PASS, 15-min stability PASS -> B10 CLOSED
- README: B7/B8/B9/B10 CLOSED, production profile (4.20 V / 450 mA / HOLD 4.05 V / full-min 4.15 V / CV 60 min /
timer 512 min / FAULT safe clamp 4.00 V) and the four production limitations; NOTES session 38
- current tree cleaned of raw B10 run logs (monitor/dmesg/snapshot/UART excerpt/action logs/register dumps/emulator
outputs); history (58dcb3d) not rewritten
- publication rules: tools/publish-sanitize.py and .gitignore keep B10+ logs to reports (*.md) and *-diff.txt tables
- LBC supervisor v1..v4 (linux/patches/b10b3-lbc-supervisor-v3.patch + b10/b10b3/lbc-v3-to-v4-fault-clamp.diff):
CHARGING 4.20 V/450 mA -> HOLD 4.05 V after 60 min CV -> battery -> new cycle on USB insert; FAULT = VDD_MAX 4.00 V clamp
- RAM tests C/B/D/D2/D3/D4 (safety timer only ends fast charge), B10B-4 actuator audit (VDD_MAX works, USB_SUSP does not),
B10B-5 FAULT clamp regression, production run, warm reboot via PON reboot reason
- cache = B10B-5 c3732515 (HW EDL write, readback + full partition verify), class-A persistent validation
- test-only hooks/images are not part of the production kernel; images with the AP PSK are not published
- B9A: read-only audit of stock LK/DT: the panel is an ST7735S 128x128 on SPI (BLSP1 QUP4,
16 MHz, mode 3, D/C GPIO116, RESET GPIO118), backlight = PM8916 MPP4 current sink 40 mA.
- B9B: upstream panel-mipi-dbi with the stock init sequence as firmware; MPP4 sink via pinctrl
+ gpio-backlight; first light with correct colours/orientation/offsets.
- B9C: fbcon (6x8, 21x16) on tty1 + getty, UART console kept, aurora-display service;
cache B9C b9ce13c9 written and verified, cold boots with LTE + Wi-Fi + display.
- B9L (RAM only): lk2nd second stage with an msm8916 SPI panel port shows a picture before Linux.
- Sanitizer: whitelist for b8/ and b9/.
B7A: QMI DMS time vs VNIIFTRI NTP (DMS = UTC - 0.28 s, sigma 1 ms; NITZ = DMS
truncated to 1 s). B7B: a 1970 -> 2026 date -s step is harmless for the modem
stack. B7C: aurora-modem probes DMS/NITZ along the start flow and steps
CLOCK_REALTIME once at the first valid sample (REG registered/attached), never
RTC; background SNTP check (query only) after START OK. 3/3 class-A cold boots
PASS (residual +0.04/+0.36/+0.84 s), cache 14fe453a written (B7C_WRITE_VERIFIED)
and verified by a normal power-on (V1, +0.26 s).
Also publishes the prerequisite R2 (boot-hang / lk eMMC investigation, T4
telnet baseline that B7C builds on) and R3 (autonomous cold boot, NCM loss)
material, and extends tools/publish-sanitize.py to r2/, r3/, b7/.
Binary images, initramfs, busybox and raw logs stay out (see b7/*/SHA256SUMS).
Sanitized research log, build/reproducibility docs, DTS, kernel configs,
patches, initramfs sources, bootchain migration plans and test logs.
B5 direct boot PASS; B6 modem lifecycle in progress.
No dumps, NV/EFS, vendor firmware or device identifiers included.
