[U-Boot] Problem booting image + device tree (MPC5200B)

[Nandini Hengen]

Dear listers,

                  I currently have a problem with the device tree - the 
kernel hangs after unpacking and trying to load the device tree.



Distribution: OpenSuse 11.1, IA-64

Kernel 2.6.29

ARCH = ppc

CROSS_COMPILE = powerpc-603e-gnu-gcc

Hardware-Revision: Phytec MPC5200B-tiny Revision PL1245.1A

U-Boot Version 1.2 incl. downloaded patches



I've tried compiling different kernel versions (2.4.x and 2.6.x in 
combination with U-Boot 1.1.4). I also found a thread which recommended 
using the newest U-Boot version and loading the dtb file using tftp into RAM 
separately. Since then I've been using U-Boot 1.2. Until now non of the 
kernel images generated seem to load (apart from the image the module was 
originally shipped with)



To create the Kernel-Image and the device tree I use:

make uImage

make filename.dtb

with the corresponding options for ARCH and CROSS_COMPILE



I tried this using two phytec modules - both of which are non-functional at 
the moment. I reckon the kernel-image or the device tree are faulty or some 
patches are missing. The Hardware-Revision of the phytec-modules is 1245.1 - 
is the hardware out of date or is my problem related to missing patches ? 
The wrapped version as well as the version with a separate device tree hang 
while loading.

I'm currently wondering whether to send back the modules to Phytec or 
compiling a different kernel and device tree would help.



I would be grateful for any suggestions in this regard!





Best Regards,



Nandini Hengen
