Hi,
See below the reason why the unconfigured kernel 2.6 sources stuck at boot.
Reason: It tries to startup from sffdca1 which is not recognized as a bootable
root fs.

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)
---------------------------------------------------------------------------------------------------------------------------------
What I did as a work-around is to modify init/do_mounts.c (issue 5) to boot
from mmcblk0p2.
Change line 442
if (saved_root_name[0]) {
root_device_name = "/dev/mmcblk0p2" ;
Afterwards it boots ok:
---------------------------------------------------------------------------------------
kjournald starting. Commit interval 5 seconds
EXT3 FS on mmcblk0p2, internal journal
EXT3-fs: mounted filesystem with ordered data mode.
VFS: Mounted root (ext3 filesystem).
Freeing unused kernel memory: 172k freed
Algorithmics/MIPS FPU Emulator v1.5
INIT: version 2.86 booting
----------------------------------------------------------------------------------------
A better way would be to modify the Kernel command line and fix the mtdblock
driver issue
Anyone any advice on this ?
Grt Ruben.
