Olimex: no battery found #96

Open markus2330 opened 1 year ago

markus2330 commented 1 year ago

When running battop v0.2.4 with battery v0.7.4 on ARM Linux A20-OLinuXino-LIME2 I get following error:

2023-02-19T14:43:20+01:00 - ERROR - Unable to find any batteries in system, exiting
Error: NoBatteries

but there is a battery:

$ ls /sys/class/power_supply/axp20x-battery/
