[U-Boot] Booting uImage on the mx31

[alfred steele]

Hi Wolfgang,
Thanks for the inputs.
So what you are saying that we have eliminated all cases of the
bootloader being at fault here except for the mach id mismatch.??  How
do i verify the mach id mismatch. Is it the same id i see on a
"bdinfo" dump on  uboot.   I looked at linux/include/asm/mach-types.h
in linux . Is that the correct place to look at?

How do i debug this kind of an issue on the BDI since it may fall
between the thin line of separation between MMU disabled and
reenabled.


Can i put a breakpoint on a specific_thing like start_kernel ..or do
you mean doing a backtrace from the point it hangs?  I am using PDK
which actually limits me to change boot switches for booting it from
NAND  or RAM.
