That is to be expected unless you have working watchdog support in your Linux kernel, too. > I have observed that the board gets reset while booting in Linux. Yes, the watchdog is supposed to do exactly that. So everything is indeed working as expected. > I followed the discussion available on: > http://osdir.com/ml/boot-loaders.u-boot/2001-07/msg00121.html Ouch.

Why don't you use the existing code for example for 440EPx from our kernel tree? > I have written a function 'reset_watchdog()' in kernel which will reset > the Watchdog Timer (same as available in u-boot) and called in > 'timer_interrupt()' of /arch/ppc/kernel/time.c' But the function is not > giving any effect. The board is still getting rebooted. arch/ppc/ ? arch/ppc/ is dead. It has been removed from the Linux kernel tree a long time ago.
