Hi everyone,

Last time around (
http://www.mail-archive.com/linuxppc-embedded@ozlabs.org/msg02602.html
) , I was trying to boot my lite5200 eval board with v2.6.20-rt3 and
was advised to boot with the dtb files.

This time around Im trying to boot my custom lite5200B board with the
dtb file thats comes with the vanilla kernel and it hangs at the same
point ( "Transferring control to linux (at address 00000000 ..." ).

I edited my dts file to be the most basic to boot linux (attached).

I booted my eval board with "DEBUG" and I got this.

## Transferring control to Linux (at address 00000000) ...
[ 0.000000] -> early_init_devtree()
[ 0.000000] search "chosen", depth: 0, uname:
[ 0.000000] search "chosen", depth: 1, uname: cpus
[ 0.000000] search "chosen", depth: 2, uname: PowerPC,5200 at 0
[ 0.000000] search "chosen", depth: 1, uname: memory

However, even with DEBUG enabled I dont get a single charecter out
from the custom board.

What am I doing wrong ?

thanks in advance.
regards
prady
