getting Linux working on IBM Walnut demo board

[Brian S. Park]

Hello all,

I'm new to embedded Linux and need help from all the gurus out there.

I'm trying to boot Linux on IBM Walnut demo board with PPC405GP.
I download ELDK, installed it on a RedHat Linx 7.3 machine.
I was able to build u-boot 3.0 which came with ELDK and it booted
successfully on my demo board.
However, when I tried to rebuild the kernel (2.4.4 which came with ELDK) it
gives me the following error.
I'm using the default configuration for Walnut board (i.e. make
rmproper;make walnut_config;make oldconfig;make dep; make pImage).

Also, the documentation on http://www.denx.de/doc/ seems a bit old (it
still talks about ppcboot instead u-boot). Are there new ocuments or FAQ's
for a newbie like me?

Any help will be appreciated.

Thank you.
