Hi, I trying to use the MPC860 onchip WatchDog.I compile ppcboot-1.1.4
with include/config_MBX.h ( I have a MBX860 board) I compile the
linux-2.4.4-2002-02-14 kernel by denx. I activate the WatchDog support
MPC860.Well, I make tftpboot then I tray to boot the
kernel but...

Uncompressing Linux...done.
Now booting the kernel

And reset.
Thats mean that WD works fine but I can't boot.
What can I do???
Modify the kernel code to service the watchdog????
Which part of kernel I have to modify???
Thanks a lot.
