Hi all, I'm after any ideas or recommendations to triage/solve a likely hardware or firmware issue.
I'm having some very odd power-related glitches with the operation of one of my two Pinephones. I suspect it's unrelated to pmOS specifically, because both phones run pmOS v25.12 (via pmbootstrap) and the other Pinephone is working as expected.
Symptoms:
- on power state change (connect or disconnect a live usb-c power cable) the phone will either try to switch on if off (as expected), or switch off if on (definitely unexpected)
- same as above, but happens when keyboard case is installed and power cable added to keyboard (so it's not just the phone's usb-c connector)
- same as above, but happens when power delivery from keyboard is turned on or off via the button on the right hand side of the keyboard case
Major things done:
- tested with jumpdrive on sdcard with no batteries connected - works perfectly
- tested with known good internal battery, keyboard case battery alone, or both (same result regardless)
- reinstalled os image, no change
- reflashed anx7688 firmware per latest in megi's tree, no change
Any ideas or recommendations? Any input is much appreciated, thank you in advance.
