I am trying to boot up the Linux kgdb-kernel.2.4.18 on a Walnut board, but
it just freezes after it uncompressed the kernel.  Here is a screen shot:
EMAC0 Ethernet Test OK.
ENET Speed is 100 Mbs...

Linux/PPC load: root=/dev/nfs
Uncompressing Linux...done.
Now booting the kernel

And it just hangs.  I think this when it's waiting for input from the
              serial port 2 from the debugger then proceeds.  I hooked up
              an other session
of minicom to the second serial port on the Walnut, but only see garbages,
              "$S04#b7,..." .  I tried all the baudrates available and got
              different outputs or blank, all of which are

Has anyone got the Linux kgdb-kernel.2.4.18 to work with the Walnut board?

Any help would be appreciated,
