JTX Posted April 16, 2019 Share Posted April 16, 2019 Hi everyone, I'm using Pine64 LTS for a project. According to AXP803 datasheet Page37 & 38, the charge LED indicator can be set to Mode A or Mode B. Does anyone know how to change this setting via sysfs, or other interface(I2c, Uart) ? pine@pine64so:/sys/class/power_supply$ ls axp20x-battery axp813-ac pine@pine64so:/sys/class/power_supply$ cd axp813-ac pine@pine64so:/sys/class/power_supply/axp813-ac$ ls device health input_current_limit online power present subsystem type uevent voltage_min pine@pine64so:/sys/class/power_supply/axp813-ac$ cat uevent POWER_SUPPLY_NAME=axp813-ac POWER_SUPPLY_HEALTH=Good POWER_SUPPLY_PRESENT=1 POWER_SUPPLY_ONLINE=1 POWER_SUPPLY_VOLTAGE_MIN=4000000 POWER_SUPPLY_INPUT_CURRENT_LIMIT=1500000 Thanks, JTX Link to comment Share on other sites More sharing options...
