Does anyone has experience with the  At91Sam7x- Eval Board and NutOs running? I think that a design with this processor could be a good and cheap replacement for Ethernut1.3 or 2. What do you think?

I have implemented PDC (DMA) and also the PWMC unit for the AT91SAM7X256 Olimex board in Nut/OS.
I think Ulrich Prinz is reviewing the code right now ;)
Hopefully the code can make it into Nut/OS.
