- Do you know a good mailing list about rtlinux and embedded systems
programming for a newbie?
You might check this site for articles and information:
I don't see any reason why you couldn't use linuxbios to start your own binary, compiled with gcc. I would recommend using linux though, and something like busybox (http://www.busybox.net/) and uclibc (http://www.uclibc.org/) will keep it small.
I believe rtlinux is now a commercial product (?); you may not need it for a tightly controlled embedded system; maybe be a custom driver or two will do it.
Just some ideas.
