Well for me both method hangs. On an extra note, reset inside Uboot works, but reboot in Linux hang. I tried adding a trace in=C2=A0syscon_restart_handle(), but the trace is never displayed. I'm wondering if that handler is ever called, or if it's just that the serial console was shut down already. Any idea what else should I trace ?
