I made a project on rockpro64 that runs continously 24x7.
Sometimes when light goes or i do software restart, it does not reboot. I have to plug out the power jack and plug it again. SOmetime it reboots automatically after restart.
Have you tried to attach RTC backup battery? The ability to restart after power loss is solely depends on RK808 power management controller. If it will be equipped by a backup power source at RTC connector, the restart may become more predictable.
I still don't know why the RK808 may not restart without of RTC battery. System voltage ramps up quite sharp and RK808 should detect the turning on reliable.
How much time the board remained without of power before re-applying? May be power supply networks or the capacitors on ROCKpro64 board was not discharged enough?
