caliston2: The "bast" is a Simtec development board, based on the S3C2410 (see [link]) not an "ARM architecture". The only thing it shares with the Reciva module is the model of CPU (as you will be able to tell by looking at the BAST on Simtec's site.) Simtec may have been involved in initial concept or manufacturing, but the design is nothing to do with them.
