The H8/3664 on the board you pointed to does not have an external bus. You
will not get uClinux into the 32k of flash and 2k of RAM on the h8/3664. In
general the h8/tiny series are intended for "tiny" applications and whiole
they may have a fairly powerful core, they do not have the advanced
capabilities of the larger more general purpose h8s parts.
The h8s is not the same core as the h8/300h it is more advanced - though
backward compatible. While the bigger parts would probably run uClinux, I
don't think they are ldeally suited - although they are great for rather
lower level stuff.
You could contact the gnu-h8 mailing list for more info - or try downloading
and reading the datasheets!
