Many, different ones. Current interest is in the ARM family and
the x86 processors.

The cross tools haven't been a problem. There are many good
tutorials on how to build them. Where I get burnt is building
the files needed for booting from flash. I've gotten stuck
(crashed) in initrd because it couldn't find the correct file
system. Put the same build on a floppy and it would boot. I
always seem to get stuck there.

BTW, one of the boards is an in house design so there are
no mailing lists.
