Hello,
i am trying to port linuxppc_2_4_devel into my mpc862/MBX board for the
first time  using eldk-3.1.1 (gcc-3.3.3), as of i know the head_8xx.S is the
first file that executes in kernel
then setup.c and so on...

but when i try to boot the kernel image from ram, i got the last message
from u-boot but i do not get any printk() message from kerne.
so i am unable to debug the kernel also..

please suggest me if i have to concentrate more on some particular section
and proceed, and how to proceed...?

thanking in anticipation
saiful

Use a BDM debugger.

And read the debugging  sdection  in  the  DULG,  and  the  FAQ.  For
example, try a post mortem dump of the log buffer.

Best regards,
