hi ,everybody.there is a CFI(common flash interface)flash on my board ,but i only use it to store my software data! how to download the FPGA configuration data in to the flash?

my system could identify the flash ! I also could download the software data into the flash, only when i download the fpga configuration data to the flash, it shows " The target board must define at least one hardware image to program an FPGA configuration." what was wrong ??

some body tell me : to download ur hardware fpga config code... u hav to use the e command to erase the hardware section (user portion of flash).. then use r command to relocate the stack pointer to the starting of the hardware section, then

nr -p <com port> XXX.hexout

u will now prog ur fpga hardware config to ur hardawre section of the flash memory !

i don't know how to run the "e" command,can any body tell me ?

thanks
