uClinux-dist on SourceForge
Kwon Seok Kuon has added Rt support for the uCsimm. He ported RTLinux v0.9J into the uCsimm version of the uClinux kernel. The patches are available at http://www.uclinux.org/pub/uCsimm/Rt-port.
The picture below shows an oscilliscope trace of a uCsimm running under NML-RTL 0.9J that was generated by the guys at Rt-Control in Toronto. The trace demostrates the output that the sample code will generate.

For more information on the Rt port to the uCsimm / uclinux read the README found at http://www.uclinux.org/pub/uCsimm/Rt-port/README.txt
