I have blown WDOG_ENABLE eFuse on SabreSD board to turn on the watchdog while device is in MFG mode. Changed the device tree for MFG to initialize wdog1 instead of wdog2 as this one is used telling by the manual.

The problem seems to be that initramfs for MFG does not have init process and watchdogd is not started (as it is part of the init) so wdog1 will not be serviceds. When I try to flash the board it resets when it starts writing the system image and I see that reset cause is WDOG.

 

How do I service the wdog1 in Mfg?
