26f016B BF-26-41, reads ID 2 times then become FF

I have this chip that I am having weird issues reading.I have a xgecu tl866II-PLUS reader






I tell it to read and it checks the ID BF 26 41 it agrees

and says that it reads



Then I try verify.
This time it got the ID correct but usually ID becomes FF FF FF and I have to replug to get it right again. So I verify some values and now I am getting bytes other than FF.




Then if I try to verify again the ID becomes FF FF FF
The data read in was all FF.
But if I remove the zif socket and plug it back in it gets the right ID again.
But still wont verify.

This chip has SPI and SQI modes. I'm not sure what that means.
I suspect that the chip isnt being read right by the programmer.
Maybe timing or voltage or handshake is wrong...


Data is all FF




weird.
Read once.. appears to work.
Re-read of verify and ID becomes FF
If you replug ID comes back
but read is all FF and verify is not FF

What the heck?
maybe I need a new config for this chip....

Any ideas ?
