PPC 750 booting... exception

[Prasad, Siva]

Hi,

I am trying to boot custom board with PPC 750.

* I tftp'd the zImage into the target and when I give "go" command, it gives
exception error. I can't understand what is going on. Below are the copy
paste of it. I am using "powerboot" as the boot loader.

- When I got the kernel from bk source (or from HHL 1.2), I had to
explicitly say "n" to CONFIG_FB in arch/ppc/config.in. If not, I was getting
compilations errors. Does this has any thing to do with booting.

- I also tried with HHL 1.2 version (kernel 2.2.14). I was having the same
problem of exception there also.

* I know this is a basic question...
What is "Prep" and "Chrp". zImage built had these two suffixes to it.

Can some one please help me out.

Thanks in advance.
