we are trying to program this chip the origional chip got erased by error so we had 3 other units with the chip copied the chip. but when we try to program it bace we get an error, i have tried programing it to intel & AMD chips same error. if i start at address 100 to the end it then programs but if i try to program the whole thing i get an error
Can you read the chip? Is the chip been erased? Do a blank check to confirm this. As I know all 28F256 chips are compatible, so, you can use other brand 28F256 type to try. IF it is working then the software may need to update.
yes we can read the chip and erase it we have tried amd & intel with the same problem i am using ver 1.62 software but have also tried it with 1.21 & 1.39 and same error
