Subject: RE: Watchdog on MPC82xx
Date: Mon, 17 Apr 2006 10:31:12 +0200 [thread overview]
Message-ID: <51DB8827D393D411BB69003048003F4601B1C2D0@tvesntr> (raw)
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
