19:36:00 USB unplugged by operator (Test D RAM image, HOLD, DMM 3.993 V, meter 0.07 A) before the discharge script was pushed
|
|
19:36:00 after USB re-plug: board found in B9C (eMMC normal boot), uptime ~58 s at first contact, RTC 3870 s (continuous since class A, not reset), PON_REASON1 0x0808=0x10 (USB_CHG), 0x080C=00 0x080D=00; charger at SBL defaults (VDD 08, IBAT 00, CTRL 90, TCHG 80/1d, BOOT_DONE 00, path 02, 05/01)

=> board was OFF after USB removal and was powered on by USB insertion; Test D RAM state lost. Discharge script killed (B9C has no VADC), no load ran.

19:36:32 UART (local time): 22:27:03 Test D image alive -> 22:27:05 SBL1 start without any kernel shutdown message (abrupt reset at USB removal); lk restarted once (22:27:05/22:27:07); B9C booted on battery 22:27:09, Wi-Fi AP 22:27:36, modem start failed (rollback full stop); last UART line 22:27:36, next SBL1 at 22:34:13 = USB re-plug (PON USB_CHG). Board was off on battery between. Excerpt t1pre-uart-excerpt.txt

19:38:47 usbpull1: B9C up 249 s, RT 01, path 02, CHG 05, PON 10/00/00/00/00/00; UART heartbeat (kmsg every 5 s) started; waiting for operator USB pull
|
|
20:08:17 usbpull1 RESULT: operator DMM 4.064 V before, 3.994 V after pull (USB meter 0.010 A); heartbeat continuous 266->2025 s (no SBL/boot), USB back 23:07:50 local (~29 min on battery): B9C survives USB removal. After re-plug: CHG_STATUS 00, CHGR RT 00, path 01 (00/01 latch, B9C has no charger driver); PON 10/00/00, uptime 2026 s

20:08:43 operator: re-plug DMM 3.95 V before, 3.954 V after; USB meter 0.008 A (00/01 latch: USB does not carry the board, board on battery)
