So this camera is an instrument on this mission?

http://dawn.jpl.nasa.gov/

Which launches tomorrow about 7:20am EDT. :-D
We get the Nasa channel on our local cable systems
so I will have to watch for sure if it is running RTEMS.

I don't know how you got that number for the LEON2 but
cpukit has 307K if you wc -l the .c, .h and .inl files.  There
are 92K in  rtems, score, and libcsupport.

But they are using all of the LEON2 VHDL and probably
not running TCP/IP or the POSIX API. It might actually be
close.
