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

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!

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? |

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