Assuming you've got working code in the flash to start with (!), one generally downloads an application into RAM that burns the flash. > Also, does anyone know if the S3C3410x is little-endian or > big-endian? The CPU will operate in either big-endian or little-endian mode. The external memory interface will operate in either big or little endian mode. However, the internal registers and peripherals are hooked up for big-endian mode. See page 4-1 in the users manual. In older versions of the part external memory worked only in big-endian mode. But in the current parts, external memory will work either way -- but it's sort of moot since internal peripherals are big-endian. -- Grant Edwards grante@visi.com
