It sounds as if you have your device being configured corectly (automatically).

I'm assuming your code is programed into your external (not on chip) flash, and compiled corectly.

The CPU needs to be set up to boot from a particular memory location. If you are usually loading code into RAM, and it runs, then the CPU is probably not configured corectly. Recompile (rebuild) your CPU with its reset location where your external ROM (flash) is. Reprogram your configuration device, and then it should boot from the flash.
