Hi there,

does the development board support programming of any onboard configuration eeprom e.g. by active serial I/F? (I'm not familiar with this board). That case - does the FPGA starts when loading from the ROM and "only" fails for the JTAG?

Well.. this does not really sounds fine - do you have warranty on the board?
