I nearly got to do a port for my company, but they then decide to use a different RTOS :-( I did take a look. My first impressions was it should not be too hard. The serial ports, SPI, timers and power management units all look compatible with the existing AT91 drivers. The watchdog unit looks different, but its not a particularly complex bit of hardware. This hardware i ment to be used with the code running from flash. The flash has zero wait states. This will however make debugging with normal gdb a little difficult since you cannot insert software break points. I did not have chance to see how well the hardware debug macro was intergrated into gdb. I think this would be the key thing to check.
