Watchdog timeout comes in before we are able to load the
kernel and reset the watchdog. Disable the watchdog late in the boot
process to be able to boot the board.

Can't you change the WDT reset timeout instead to a higher value?


I tried that, but the HW has a max timeout of 15984 ms. Unfortunately that's not
enough.

Nearly 16 seconds is not enough to boot into Linux so that the Linux
watchdog daemon can take control?

Thanks,
Stefan
