The only help I need is with gcc, or ppc_82xx-gcc, to be precise. I have no idea how to give it a single .S or .asm file and tell it to

create a .bin.

Makefiles? I only know how to use readymade ones, not to how to create

one.

This example should help you.I used it when i did not have my debugger up and running,

I use a montavista ppc_82xx- toolchain .My uboot source is in /home/bharath, textbase is 0xfff00000 . I used my custom init file's and my c (quick_test) file to test my target board.

Change them to use for your configuration.
