TMS320C6748: Will sfh_OMAP-L138 flash utility work if my custom board does NOT have ANY DDR memory?

Part Number: TMS320C6748

I have a custom DSP board with only a C6748 with external SPI FLASH and no DDR or OMAP.  When I attempt to erase or program the SPI flash with the sfh_OMAP-L138 utility, it stalls waiting for SFT.  What do I need to change in the utilities to make this work?  I have downloaded and installed all of the tools and can successfully rebuild all of the utility files.
