PaulMorrison Posted November 5, 2018 Posted November 5, 2018 Hi, Im trying to modify the configuration of AXP209 in the A20-SOM204 to change the behavior of long and short press time to make a long press shutdown the board and a short press wake up, following the datasheet: http://dl.linux-sunxi.org/AXP/AXP209_Datasheet_v1.0en.pdf and trying with the register: https://linux-sunxi.org/AXP209#REG_36H:_PEK_key_parameter_settings but with not success. To wake up the board from standby we are simulating a POWER press as a response to an external signal rise up, but we need to NOT shutdown the board when it is already ON when this signal rise up, but after trying to change the AXP209 parameters, still, any instant press of POWER shutdown the board. Is this possible with some tweak in the AXP209 configuration? If not... there is some other way to prevent armbian to shutdown at power press?
