Yeah I can only imagine ...
I don't think my only test fried the card, it show the same behavior
before and after so I guess ( hope ? ) I'm lucky.
The slot does indeed work, I just came across a Intel EEPro100 card,
like the one I used on other dev kit. I'm sure it's 3.3v/5v compatible
and it's recognized without problems.

I don't have a debugger ... But I think I'll invest in one soon ! ;)
How can I dump the logbuf area ? I saw a discussion on this ml about
this buffer, is it fixed in memory ? How to find it's address ?

Could you send me a kernel image you compiled with the config at
http://www.246tNt.com/mpc5200_config ?
Maybe my compiler is wrong again. The ELDK binaries didn't work ( I
don't have the good glibc version on my machine ). I'm downloading what
I need to try to compile it right now ...
I've also put http://www.246tNt.com/uImage wich is not bootable on my
board ...
Basically the config is default + USB + IDE ( HD & CDRom ) + SCSI disk
support ( for memory sticks on USB ) + Misc filesystems and partition
support.
On http://www.246tNt.com/mpc5200_config is a sample .config file that
makes the kernel to not boot at all.
