> I suggest you reference the Linux kernel support and see what is needed. Coping GPL code means the code will not be accepted into RTEMS so you need to implement things yourself. I think the Xilinx demos are based around FreeRTOS so again be careful of the licenses for this code. If the license here is not suitable then I suggest you do not reference or follow that code so any work you do is not tainted. Also please send me a private email if there are license issues and we can take this off list.</p>
