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. >> - When I change options in the kernel to support new stuff I need, like >>activating USB host & IDE controller, the kernel don't boot at all ( or >>at least, I don't see on the serial console it does ).

I saw a discussion on this ml about this buffer, is it fixed in memory ?

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. Sylvain Munaut ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
