RE: Help with a board similar to the Xilinx ML403

Can I see your xparameters.h and kernel .config files please? EDK =
project can help as well, or at least MHS & MSS files along with BSP TCL =
scripts - I think you use some Linux BSP, right?=20

Also how do you load kernel - using u-boot? If so, can you please define =
DEBUG in cmd_bootm.c file and send me output?

Thanks,

Leonid.=20

Subject: Help with a board similar to the Xilinx ML403

Hello.

I would need some help to understand what is the problem...
I am a bit lost...

The board is very similar to the Xilinx ML403 with a Virtex-4 and PPC =
405.

What can I provide to make the debugging easier?

Can the problem be the content of the initrd RAM disk?

Thanks for your help.

Luca.
