Hi

I have write cfg files for AT91SAM7A1-EK board from ATEML

here’s a link to the board datasheets

http://www.atmel.com/dyn/resources/prod … oc6114.pdf

and here’s a link to the board processor AT91SAM7A1

http://www.atmel.com/dyn/products/produ … rt_id=3450

I’d like to share the cfg files with the forum members and get feedback if there’s any thing wrong with my cfg files
