I pulled the USART code from Olimex and ported it to the Yagarto Eclipse environment. In the process, I found an issue with the Olimex code in that it setup the baud rate generator clock with the wrong values.

I used the Jim Lynch "blinkie" example framework as a starting point for the Makefile and other Eclipse environment settings such as the OCD "program" target. After I got the USART code working I tested both ports and they were fine.

I have exported the resulting SAM7P256 USART project as an Eclipse/Yagarto export that you can download from the Sawdust download section.

I started doing a similar port of the Olimex MMC/SD code but have run into some problems with it. I'm working that issue on the SparkFun forums - when I can get that working, I'll write it up, but in the meantime, you can get the ported code in the downloads section of sawdust. It compiles but will not work (for me.)
