Your kernel cannot mount the root file system. Please check:
- Does your kernel know the location of your root file system? (I do not know
whether this applies to your arch) Type "rdev YOUR_KERNEL_IMAGE". It shows
you where your kernel expects your root file system. If you have not changed
it, it is probably the block device which was the root device on the machine
which compiled the kernel at that time. If if does not equal the location
of the root file system on your embedded system, append it as a parameter,
e.g. root=/dev/sda2
- Do you have the file system compiled in?
- Do you have the block device driver compiled in?
- Is the file system mountable on your pc without errors?
