I have used FreeRTOS in couple of projects at work. It works fluently in ARM7 and Cortex-M3 with ports provided.
Now I’m interested to toss in an ARM9 for a personal project. However I cannot find any existing port for LPC29xx/ARM968E-S (and GCC). Have anyone made any work with this so far? I’m still unsure how hard it would be to do the necessary port myself, but any clues for this are welcome as well.
