I have installed a XCF08P EEPROM in my fpga board. The first time i wrote a program to it, it worked fine. But I can not erase the EEPROM. When i write to it now verify fails, I suspect i have to erase it before writing a new program.
Using: Impact 8.1.03i JTAG programmer: JTAG 3 i belive (Parallel port), came with a digilent starter board.
Thanks Andreas Beier
