Hi Li,
I'm working on a lite5200b too but with a 2.4.25 kernel. Anyway, I found some
problems to launch the 2.4.25 kernel from the U-Boot version that comes with
the board from Freescale. I fixed some bugs in this U-Boot version and sent a
patch for the U-Boot 1.1.4 version to the U-Boot users mailing list. The patch
is not yet accepted and added to the git repository but I suggest that you
apply this patch and try it again.
Another suggestion is not to use a low address to copy the kernel image (in
your case 0x100000, try 0x500000 by example). The kernel is decompressed at the
0 address and your kernel could be overlapped.
Good luck,
Jose Maria Lopez.

Asunto: boot failure on lite5200b board
Hello all,
For my end-of-study project, I am working on an embedded system with reference
of freescale's lite5200b reference board. I was trying to boot Linux 2.6.15 on
the board (with the fec and bestcomm corrected). however the booting was stuck
at the following stage:
U-Boot 1.1.3 (Feb 6 2006 - 09:56:46)
## Booting image at 00100000 ...
Image Name: Linux-2.6.16-rc1
Image Type: PowerPC Linux Kernel Image (gzip compressed)

id mach(): done
MMU:enter
MMU:hw init
MMU:mapin
MMU:setio
MMU:exit
setup_arch: enter
setup_arch: bootmem
arch: exit
I think it's probably the problem of kernel configuration prior to compilation.
Has anybody got 2.6 kernel working probably lite5200b?
