Hi,
    hello!
    I'm trying to get a walnut board booted. I'm using linuxppc_2_4_devel pulled from denx yesterday. I'm getting the "Real time clock seems stuck" message then nothing, no messages after that. I found a brief thread about this.

http://lists.linuxppc.org/linuxppc-embedded/200106/msg00113.html

Have the changes suggested been put in the devel tree? If so, can someone offer some advice on how to proceed?

Here's some console output.

then nothing after that.

Any ideas? I've searched the archives for walnut boot problems. It seems like most people just get it running and that's that.



thank you.

Since you are using PPCBoot and a linuxppc_2_4_devel kernel - did you
check that "clocks_in_mhz" is _not_ set in your PPCBoot environment?
