This page presents some projects that use the GNU Development Chain.
1. NanoK
NanoK is a very small kernel for the 68hc11. It works with the GCC port.
It is maintained by Yann Gouy:
nanoK.tar.gz
2. Ethernet on 68HC11
Tom Parker designed an Ethernet board using a Cirrus/Crystal CS8900
controller and plugged it to an 68HC11-F1 board. He wrote a small
IP-stack and Ethernet controller in C. This must be compiled under
GNU/Linux with the GCC port (due to the use of Linux network headers).
