Which kernel mod needs to be loaded to get battrey support on cubietruck?

[pet]

I'm on 'cat /etc/os-release|grep ARMBIAN_PRETTY_NAME' = ARMBIAN_PRETTY_NAME="Armbian 24.11.1 bullseye"

Providing logs with

 

PASTE_SERVER_HOST=paste.armbian.de armbianmonitor -u

 

 helps with troubleshooting and significantly raises chances that issue gets addressed.

Hi Pet,

 

The axp209 modules should already be loaded by default, if not then they should at least be included in the kernel. This is the pmic onboard the cubietruck. Are you using a lipo or coin cell for rtc? You can check the current state by look at '/sys/bus/i2c/devices/i2c-x/x-0034/battery. Replace x with the i2c bus that the axp209 is assigned to. Normally this should be 0 but not always the case. For example this it what it looks like on my device:

[    2.973703] axp20x-i2c 1-0034: AXP20x variant AXP209 found
[    2.981221] input: axp20x-pek as /devices/platform/soc/1c2ac00.i2c/i2c-1/1-0034/axp20x-pek/input/input0
[    3.000378] axp20x-i2c 1-0034: Backup (RTC) battery charging is disabled
[    3.000562] axp20x-i2c 1-0034: AXP20X driver loaded
[    5.367992] axp20x-gpio axp20x-gpio: DMA mask not set
[    5.382424] axp20x-gpio axp20x-gpio: AXP209 pinctrl and GPIO driver loaded
[   21.124944] axp20x-adc axp20x-adc: DMA mask not set

 

best of luck
