Subject: Embedded O/S for GPL

Anybody interested in an embedded O/S that supports GCC? I've written (and
am continuing to write:-) an O/S that supports C/C++ on the i960 and can
be pretty quickly ported to other targets that gcc supports. This is no
toy and my company is using it for real work (why else would I write
it?-) but we are releasing it under GPL terms. I am starting to make
snapshots available for FTP, and presumed people on this list would be

It is called uCR and it is relevent to this list because it specifically
supports cross compilation with the GNU compilation tool chain. I got tired
of worrying about whether GCC was supported on some target O/S for the chip
at hand and decided to do something about it. Plus, uCR meets some specific
design goals (threads, light-weight, portable, embedded O/S, GPL License).

Point your browser at and
pay particular attention to the section on uCR. Documentation in HTML can
be browsed at
