Load the flasher program into RAM, and run the upgrade out of RAM using polled serial I/O to avoid annoyance and complications with interrupt tables. >Also, does anyone know if the S3C3410x is little-endian or big-endian?

Unfortunately, I can't find which it is in the Samsung >documentation. If you can't find a pin that is documented to have this behavior, then that connection point on the core is probably tied internally and not brought out to a pin. === Lewin A.R.W.
