Hello,
I am using the GQ-4X USB programmer. I am trying to program the Atmel 29C040 DIP. It won't write properly or verify

The chip identifies as "1F5B".

1. It looks like the writing completes successfully, but the verify fails almost immediately.

2. When I read the contents of the chip, the data is similar but certainly not the same. IF I read the data from the chip and program those same contents, the end result is they do not match.

I have tried a few different chips with same results. I even tested a few chips someone else had burned, and the programmer rendered them unusable even when trying to write back what was read into the buffer (from that same chip!).

Thank you. tim

Quick update. I was loaned a 29C040A (only difference is the ID code and 256-byte sectors versus 512 on the 040). The 040A does not identify properly by the programmer.

I also tested filling the buffer with 0s and 1s. On the 29C040, bytes 0x0000-0x4000 look like the 512 byte sectors are only written 256 bytes and duplicated. After 0x4000, the fill bytes are written to half of the sector.

Since the Winbond 29c040 is similar, I tried selecting it. The bytes in 0x0000-0x4000 still got messed up like Atmel, but after 0x4000 it seems to program successfully.

Seems the programmng algorithm may be wrong for these chips.

Hello, just checking to see if there are any thoughts or developments for these two Atmel chips? I am stuck right now. Thanks

I think the algorithm need to be updated.

Thank you. I would be happy to provide a test chip if that would help correct the algorithm. -Tim

Check back to see if there is an update or if a chip would help to correct the problem. Thanks!

Hi any word on the algorithm? Thanks!

Checked AT29C040A TSOP32 chip and it works. Check your adapter if any.

My chips are DIP-32, no adapter, placed directly into the programmer.

I have tried multiple 29C040 chips. Do I have a bad programmer?

Here is an example of what happens when I blank the data buffer andwrite all 0s to a 29C040. Programmer says write is successful. Reading the chip shows it was NOT successful. Thank you.. Tim

Still looking for assistance on this 29C040/040A programming. Need to know if the programmer is bad or if the code just won't work with these chips. Thanks.
