Downloading Linux image using Riscwatch

[Aman]

Hi

I have ported rom monitor code[Openbios from IBM] for my custom
board[PPC440GP Processor]. The custom board doesn't support ethernet. Now I
want to download a linux image to the RAM of my custom board. What linux
image I have to build to download to RAM using JTAG of Riscwatch Debugger .

Thanking you in advance
Regards
Aman
