Ok I just tried to program for the first time and I am having trouble with the AT29C256 chip. When I try to program it gives me Program Failure Address: 0h ,Programming BYTE:10h,Read BYTE:FFh Aborting Programming

Can someone please help me!!!!!!!!!!!!!!

 

is the power pack plugged in and is there a red/green led on without it connected to the pc ??

 

yes it is plugged and there is both a red and green light both on with it plugged in to the power supply

After searching last night a good bit I think I need to stack my bin file to get it to 32k How do I go about this I am not familar with how to do this with DOS/ prompts could you explain this or give me a link that will explain this to me, Thanks

 

Bet you have it inserted wrong in the zif. the at29c256 is 28 pin, the zif will take up to 32 pin chips. make sure that you put the chip to the rear of the zif, ei leave the first two rows open (pin1 and pin 2, 17,18. However, as I have done this myself, be aware that the eprom may have fried. place it correctly and see if you fill it with FF's

to stack a 16K bin into a 32K bin..

have a copy of the bin on C: drive.

in dos at c: prompt.

copy b/ 16k.bin + 16k.bin 32K.bin

example.

copy b/ malibu16.bin + malibu16.bin malibux2.bin

malibux2.bin will be your combined bin file located on C:

 

Ok I was putting them in wrong I think, now I cant get it to program, again it gives the same error message as stated before.

It is also telling me when I read the chip that it is all FD's not FF's
how can I erase the chip before programming? I also tried my other chip incase I messed up the first one and get the same thing.

I am so screwed up any ideas???????????????????

 

I got that message when the chip was bad, I got more and they program fine.

 

I got my chips from Graig Moates where did you get yours from?

 

If it won't program to all FF's, its more than likely fried..

 

Got mine from Moates also.

 

I think you need to put the forward slash in front of the b:

copy /b malibu16.bin + malibu16.bin malibux2.bin

I get the same error message. My BIN is a 32K so I don't have to stack it. It will erase fine and it reads all FF's however it will not program. I am also using the 29C256's. I have one that wont erase, does this mean its fried? I inserted them wrong, but I had one with a BIN on it and when I fixed it and put it in right it read the BIN fine, erased fine, Blank checked OK but just won't program.

 

I forgot to mention when I read it and it reads all FF's I will program it and it programs the FF's fine. It will also verify OK.
