Cant believe It’s only me that has found what seems to be a basic bug, however figured I would mention it to see what I haven’t set right!!
So – If I insert a 4 Meg eprom, and program it with an 8 Meg image it programs and Verifies fine?!??!?! How can it verify a 4 meg image on an 8 Meg chip – it would never have written fully in the first place as the chip storage isn’t physically big enough!!! (in this example, I am using an 8Meg image onto an M27C4001 Eprom….
Surely this cannot be correct¬¬¬ (Using software GQ USB Rel 7.07 on your GQ-4x4 programmer…)
Please could you advise – I’ve screwed up twice now, since my last programmer used to verify and Alert me when it didn’t fit, and if i get lazy and don't calculate the right chip size it's letting me burn them and send to friends happily... and then doesnt work!!
Thanks!
Paul

If you load the data file larger, then it will be truncated to EPROM size.

I recently had very interesting result reading ST manufactured chip M95320W, which was not blank. I use GQ4x4 on Windows XP, latest software and all worked fine until I came to this issue. Chip read as blank! Many times over, re-insertion, double check connections, reboot, nothing helped. I used a different programmer and was able to finally extract the code from it. Very upsetting and worrisome issue.
Has anyone seen similar before? |

I tested it works fine.
One thing you can try is to select totally different chip, such as a PIC chip, and then select your chip again.
This will force the software to update the algorithm firmware. And you should receive a message: Configuration updated!

Not programming/Verifying correctly??!!
