PinePhone 1.2 - Linux mobian 5.15-sunxi64
I just recently reflashed my PinePhone with Tow-Boot and the mobian-installer-pinephone-phosh-20220508 and since then the keyboard battery is not being charged.
The fully charged battery was completly drained and remains at 0%, in Gnome Settings --> Power under Devices kb151 is listed with 0% charge and the Powersupply app has the Keyboard Case listed as well with Capacity 0%, Voltage 2.601V, Status flickering between Discharging and Charging (0.02W) and Health Good.
demsg returns --> kb151 2-0015: Charger read failed - MCU returned 0xff
Before the switch to Tow-Boot / Mobian I had U-Boot / Mobian and the battery in the keyboard case was working just fine.
It was keeping my phone charged and was a nice companion as it extended the usable life of the phone to a fine 24hrs.
Since the switch to Tow-Boot / Mobian, the once full battery in the keyboard case was completly drained by the phone, but never recharged.
As soon as I plug in the power supply it starts charging the phone (charge current alternates between 1.2A and 1.7A) once the phone battery is charged it stops charging (charge current drops to 0.3A) and the keyboard case battery remains at 0% charge, i.e. it does not charge the beyboard case battery.
Power is connected directly to the keyboard case and the top-right corner of the keyboard case gets warm indicating that the electronics inside seems to be working.
Any ideas on how to get the keyboard case battery back to working order?
I do updates on a daily basis via apt, so should have the latest version of mobian and software, and I am using the PinePower 120W Desktop Power Supply to charge the phone.
