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is the hardware out of date or is my problem related to missing patches ?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
