For one thing, the "image.srec" file is not a stand alone bootable image. It expects to be loaded via some type of boot laoder. So it expects the 5272 and SDRAM to be initialized when it starts running. Loading image.srec into FLASH will not work on its own. image.srec is designed to be loaded by dBUG (as you are trying to do) and then run from dBUG (using "g 0x20000").
