I wound not suggest using redboot on the AT91SAM7S256. It does not
really have enough ram for it to be useful.

The AT91SAM7S devices are designed to run there applications from
Flash, not RAM. That is why there is no support for RAM startup in the
HAL. The test programs should just work. Burn them into flash and run
them.
