Hi, Iīve some 28F102īs here which I can`t delete with GQ4X.
Used with ADP054.
Writing is no problem.

On standard speed it will go to 50%.
If I reduce speed it goes to 100%, but wonīt response anymore then and chips are still not deleted.

(run program "as admin" and compatibilition mode wonīt make a difference).

Any suggestions? Itīs really urgent

It was 7.07. (its a GQ4x4)
I removed driver, installed 3.0 from downloadpage and Software 7.11,but problem seem to remain. Hangs on 100% and chip not erased.

I use Win 7 32bit.
Question: I installed Gq4x4 USB Driver 3.0 Win 7 32 bit:
Am I right that 3.0 is Version-Number from this driver , or am I wrong and it is only for USB3.0?


Edit, one question more:
My ADP054 has two Jumper (J1 and J5). I tried all combinations (1-1/1-2/2-1/2-2 and to be sure I tried 0-1/1-0/0-0/2-0 and 0-2 too)
The Right one is J1 on 2-3 (2) an J5 on V4 (2), or is this wrong?

GQUSBprg 7.11 needs USB driver 3.0 to be installed first.

J1 2-3 short 27c322, 1-2 short for all others

J5, chip compatibility jumper. Only change it if the chip has inconsistent reading, writing.

I now repaired my older GQ3X (74HC245N was faulty) installed SW 6.38 on my other Laptop and was able to delete them (only on Speed -2).

So its not really urgent any more and I can also tell that my ADP054 is okay.

Only on GQ4x4 deleting is absolutley not possible. Bar goes to 100% and all LEDīs stay on.

A solution would be great

Someone should compare the device line of 6.38.

The person is question has the same problem which there is a recent thread about. The issue with the chip was reported back in 2017 which is the year the first post made. It is now 2020 and the issue has not been fixed. No one from the company has even acknowledge that there is an issue with the gq-4x4 programmer with regards to the 28F102 chip. Hence why the poster made the very negative post.

You do have to admit anniel that no one from the company seems interested in the forum anymore and as such, customers are getting very annoyed, and rightly so in my opinion.

Did they call MCU Mall? I don't think so.

Your are correct it is not but as paying customers of their products, I do think they have a responsibility to visit the forum from time to time and assist their customer(s) where need be or is that asking for too much?

You are right but for long time known working chips like this the best that could be done is ask to send the chip in to look for inconsistencies. Also ask for adapter or programmer if those are suspected.

Prior to erasing, try to write chip with bin filled with 00's.
So:
1. Write non empty chip with bin filled with 00's.
2. Erase.
3. Write proper bin.

It's working for me 100% of time with M28F102.

That would be a nice trick to try on a difficult M28F102.

Thank you for the tip!

If your having to make a bin file filled with blank spaces and then write that bin file to the chip before you try to erase it then surely that means the chips are faulty and not the programmer because during the erase process that is all the programmer does, writes blank spaces to the chip.

You are right and the M28F102 seems like a difficult device for fake/defective/damaged chips.

Just did a few tests. Chip burned with random values generated by HxD erases standard way with no problem. Very same chip burned with car ECU bin, which contains long blocks of FF-s at the begining, can be erased only using 00-s trick.
Do you think it's chips fault, or the programmer algorithm considers long block of FF-s as empty chip and cancels erase process? Serious question, I'm just hobbyist and have no clue.

When erased are the FF locations shifted to a somewhat lower value?

No, FF-s stay as they were. Other values are changing with every erase attempt.

Below I've attached original bin, and readouts after every of 5 erase attempts.

And here is bin with random values which erases fine in 1 attempt.

Any way you can monitor VCC to the chip for voltage droop or spikes?

VCC is 5.2V during read/write/erase and VPP is 12.2V write/erase. No drops no spikes, but I have only cheap, slow chinese multimeter, so it may not be very accurate measurement.

Indeed, a scope would have been better. At least there is no major disturbances.
