SPI booted program stops working when SDRAM is used

I'm using the BF512F which has internal flash memory that is accesses via SPI. My program also makes use of some SDRAM I have hooked up. When I build and load an executable file using the HPUSB-ICE emulator, everything runs fine, including the SDRAM.


I also wrote a driver for the flash programmer. If I don't make use of SDRAM, then I can build a loader file, load it using the flash programmer, and boot the program from the internal SPI flash.


The problems happen when I try to use SDRAM. Then nothing happens. I've looked at anomaly 0500049, and this looks like it might be the problem. Has anyone else had similar problems?
