Hi monkeyboy

I have set the reset address to point to the epcs in the SOPC builder. However, the program_flash script that the nios2configtool generates insists on programming into the flash (uses the --flash=U5 flag in the elf2flash command). When I try to manually change this command to use the --epcs flag instead of the --flash flag, it complains that the --epcs flag should not come with a --reset flag (which is right), but after removing the --reset flag, it complains that the --reset flag is missing.

I've made sure that the design is written to the flash by programming something else into epcs and then going through the scripts created by eCos, but the design from the epcs keeps coming up.

As I've mentioned in my first post, when I use build->templeate in the nios2configtool I see that the system called default for a niosII developement board has support for the AMD flash but no support for serial flash memory is listed.

Any ideas ?
