[U-Boot-Users] Booting Standalone App?

Hi there,

So what are the steps to get u-boot to boot the hello_world example? I'm
evaluating the PowerPC 440-based AMCC Yosemite board. This is what I have
done:

gzip hello_world.bin

mkimage -A ppc -0 linux -T standalone -C gzip -a 40000 -e 40004 -n
"Standalone" -d hello_world.bin.gz hello_world.ub

Then I loaded the ub file onto the board at 0x40000. Then when I tried to
bootm 40000, it would uncompress the standalone app (Uncompressing
Standalone Application ... OK) then stop after showing 2 symbols.

What am I doing wrong?

I'm a complete newbie to u-boot and I've tried to find discussions online
and reading the DULG, but I'm not having too much luck...

Thanks!
