Just read a little on the MPU watchdog timer. It looks like the default values would
have caused a reset after ~10s. So if your board is rebooting after 4 minutes,
maybe the bootloader is turning it on?

I've left a board on in the bootloader for hours without seeing a reboot, so either
the bootloader I was using disables the watchdog, or it's not armed at reset.
