I have an Argon One V2 case with a Raspberry Pi 4B 8 GB running Debian Bullseye 64 bit.
I want my RPi4 to boot up automatically when the power comes back after a power outage. The default behavior is that the RPI4 wait until the power button is pushed before booting up.
I found a description on how this could be set up here: https://github.com/Argon40Tech/Argon-ONE-i2c-Codes/blob/master/README.md. The Argon One Mode should be changed from mode 1 (Default) to mode 2 (Always ON Mode).
I found the Argon One device (0x1a) with the command “sudo i2cdetect 1” as expected.
As decribed in the link above I run the command “sudo i2cset -y 1 0x01a 0xfe”.
After switching the power off and on on the Argon One M2 case the behavior was same default behavior as before, the RPi4 did not boot up automatically. I still had to push the power button.
Has someone tested this successfully in a RPi4 with 64 bit OS?
