The STM3210E-EVAL board is attractive for many developers because it features sufficient (external) RAM to permit initial application development in RAM. This generally allows a faster download/debug cycle and provides greater flexibility in the use of breakpoints. However, I would expect many production Cortex-M3 designs to feature no external RAM, requiring a switch to ROM startup later in development in order to reduce RAM usage. For avoidance of doubt, you can use RAM startup without RedBoot by disabling CYGSEM_HAL_USE_ROM_MONITOR. I hope this helps...
