seif Posted January 18, 2023 Share Posted January 18, 2023 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. 0 Quote Link to comment Share on other sites More sharing options...
seif Posted January 18, 2023 Author Share Posted January 18, 2023 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.

seif Posted January 20, 2023 Author Share Posted January 20, 2023 (edited) Hello! Lemaker Banana Pi M1 Armbian 22.11.1 Bullseye with bleeding edge Linux 6.0.10-sunxi 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. Edited January 20, 2023 by seif 0 Quote Link to comment Share on other sites More sharing options...
