RE: [microblaze-uclinux] kernel won't boot

["Eric Lynum" <elynum@xxxxxxx>]

I did a mb-objdump on my kernel and the data on the address after 30000058
is not the same that is actually being written into the sdram.
For instance 
At 30000054 I have a561e000 which is what I have in the sdram
At 30000058 I have b000300a but I have b000300d in the sdram
After that it looks like every thing is moved to the left by 2 spaces for
instance at 30000068  it should be b0003009 but I get in the sdram f0b00030.

I have no idea why the sdram is getting different data after 30000058.  Any
clues anyone?

That doesn't look right.  Next thing I would try is to load the kernel into
memory via xmd and then single step to see where things go awry.

mb-objdump the kernel in uClinux-dist/images/image.elf for a listing of the
assembly.
