bpi m1 with a battery: kernel panic when shutdown -h 0

[seif]

Hello armbianers !

 

Armbian 22.11.1 Bullseye with Linux 5.15.80-sunxi on a banana pi m1

 

I've connected a lipo battery to my bpi m1, and now when I try to shutdown -h 0, it ends up in a kernel panic and instead of shutting down it remains powered up. Is there anything I can do to fix that? I'd know how to shut it down talking to the axp209 via i2c, but I'm not sure how/where to put that, or if that would be or not the proper way to go.

 

Thanks,

George.

Ok, never mind. I went in a loop to [ armbian-config/switch to other kernels, chose the next newer kernel, apt update && upgrade ], and after a few rounds I got to:

 

Armbian 22.11.1 Bullseye with bleeding edge Linux 6.0.10-sunxi

 

In which everything works as it should ! :-)

 

shutdown -h 0 is now turning it off.

 

Cheers,

George

Hello!

The problem with the kernel 6.0.10 is that /sys/power/axp_pmu/ is no longer there... nor anywhere else as far I know.

 

tree /sys/power/axp_pmu/battery/

/sys/power/axp_pmu/battery/

├── amperage

├── capacity

├── charge

├── charging

├── connected

├── power

├── ts_voltage

└── voltage

 

Any ideas why? Can I fix that? How?

 

Thanks,

George.
