The MegaWatch Wireless PlatformMaster's Thesis - Emanuel Corthay10 Operating system10 Operating systemThe boards, embedding an ARM 9 processor, can run various code and Operating Systems. Linux2.6.0 was successfully ported to the MegaWatch boards by Cédric Gaudin and several semesterproject students during the winter 2003-2004. eCos has also been ported on the platform for realtime embedded applications by René Beuchat and Cédric Gaudin.The main focus of this work was more on a lower hardware and software level, and thus, noinformation on the operating system is available at the moment.70 / 83
