I have a new GQ-4x4 and have successfully programmed several 32K EPROMS, however there seems to be an issue when I try to program 64K ones.
I have tried with AM2764 chips from MD and D2764 chips from Intel.
If I do a blank check they come back as blank, but then again it comes back as blank even when there is nothing in the ZIF socket, so that doesn't really prove anything. Doing a read returns all FF and if I change the first FF to 00 and do a burn it fails on the first character saying it wrote 00 but read FF.
Any ideas here as to if the unit is faulty or is a software issue.
Here is the log
ID check skipped
Blank checking... Buffer
Elapsed time: 1.48 seconds.
Chip is blank
ID check skipped
Reading... Buffer
Elapsed time: 1.50 seconds.
Read completed.
ID check skipped
Writing... Buffer
Elapsed time: 0.96 seconds.

Write failed, Address=0x000000, Buffer=0x00 Device=0xFF
Write failed
Thanks

It would appear that it is the definition ffile that is the source of the issue. I just tried the 2764(21V VPP) in the ALL(GENERIC) section and that works OK. |
