RE: Watchdog on MPC82xx

Mike,

I tested several times last week but it didn't work for me.
I had made the changes in U-boot as you say, but it keeped
reseting at the time. In fact, in the log_buf I can see
several printk's after setup_arch (where ppc_md.heartbeat)
is assigned, but the watchdog counter is not reloaded.

Which could be the difference? I am using ramdisk,
and a MPC8248 clocked at 100MHz, but I don't think
this will be the reason.

Now, someone has proposed me to try reloading WDT in
printk calls. I will test.

Best regards,

Alex

So, any other idea? Is the WDT on MPC8248 usable at all?
 

I used the watchdog timer on mpc8247 and mpc8271. The mpc8248 watchdog 
should be the same. I used ppc_md.heartbeat to write to the watchdog 
registers and it worked fine. Also, I've added WATCHDOG_RESET()  to 
common/cmd_bootm.c in U-Boot just before the jump to kernel.

Thanks,
