Custom STM32MP157F board sometimes hangs on reboot

Hi!

Our custom board sometimes halts instead of rebooting. Has anyone already seen something like this?

Connect to device by terminal or ssh:

$ reboot

The terminal then logs all shutdown messages, but sometimes (every third?)

it stops with this:

[ 4253.287388] reboot: Restarting system

INFO: PSCI Power Domain Map:

INFO: Domain Node : Level 1, parent_node -1, State ON (0x0)

INFO: Domain Node : Level 0, parent_node 0, State ON (0x0)

INFO: CPU Node : MPID 0x0, parent_node 0, State ON (0x0)

INFO: CPU Node : MPID 0x1, parent_node 0, State ON (0x0)

System halts and does not reboot

No idea how to fix that ....

Bye Gunther

Hi @GLaure​ 

Could you share BootROM log (if it fail at that stage) ?
