RE: Real time clock seems stuck

You may be loading the code too low.  See the comments for the
CFG_BOOTMAPSZ parameter in CONFIG_WALNUT405.h and cmd_bootm.c.  Try
loading at 0x800000 instead.

Subject: Real time clock seems stuck



Folks,

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.

Thanks
Craig
