Hi, I've recently upgraded to a GQ-4X4 after blowing up my original GQ-4X programmer.

The frustrating thing is that now I'm having trouble getting it to work with some chips.

For example, the Atmel AT90S2313 ... which I used to be able to program in cicuit with a cable and adaptor I made up years ago ... no longer works.

Monitoring the various pins MOSI, MISO, RST, SCK with the adaptor plugged in or not ... I get no signal at all on any of them ... though the Vcc (which is not connected to my adaptor) does come up to 5v when accessing the chip.

Also Atmega16-16AU no longer reads or can be written ... even though I have done it many times with my old GQ-4X ... though this one does have signal on the relevant pins.

Neither will show a chip ID code.

I can program eeproms 24C04, eproms 27C256 etc etc quite happily in the socket.

Can anyone offer me any suggestions as to how to get it to work again please.

Thank you.

Next step is to open up your GQ-4X and look for bad solder joints, charred parts, burnt traces or blown chips etc.

Ok thanks ... happy to do that ... but will that void the warranty?

If it still is under warranty just exchange it.

I had never noticed it before up there on the menu bar.

Most of the tests seemed ok ... BUT ...

I assume on the Hardware I/O Diagnostics window ... that I can turn on and off individual pins ... and then measure them to see that they operate correctly.

If that is the case ... address lines A13, A14, A15, A17 A18 do not function at all.

The rest of the address and data lines seem to switch on and off ok.

So I guess that explains why some chips do not work ... and others do.

Now of course ... the question is ... what can I do about it?

That's what I hoped would happen, but it did not.

No, I have not. I did a quick search but couldn't find reference to it. Can you point me to an explanation please?

I'll do that before I try and load an earlier version. Thank you.

Yes, I did restart the software. I've got into the habit of doing that any time I have any issues ... it often fixes things.

Just some additional information ...

I cut the lead back to less than 10cm.

I also now realise that for the AT90S2313 the Vcc pin does not power up either ... so there's no way it can ever read.

I've also hooked up the external supply in case that is needed ... but no difference. Mmmm!

Looks like something wrong with the software.

I did find lower down, a reference to "AT90S1200*ISP" ...

See here ... ";Name="AT90S1200*ISP",ID="1E9001",Class="AVRISP",Category="MCU",MFG="Atmel",CodeSize="1024",EepromSize="64",ChipMode="AVRISP",Adapter="AVRISP connection.";"

I assume the semicolon effectively "comments out" the line ... but even after removing the semicolon ... I don't get access to AT90S1200*ISP in the devices list. I had wondered if I may be able to use that setting to make it work.

Reading the manual, I wondered if my lead is too long ... though have used it many times in the past with the older GQ-4X.

I will shorten it and try again ... but am really not hopeful because of the fact there are no signals on any of the lines anyway.

I did look at the devices.txt ... but with the little I know it looked ok.

Thanks.

Does the line look exactly like this?

Name="AT90S2313 (Serial Mode)",ID="1E9101",Class="AT90S2313",Category="MCU",MFG="Atmel",CodeSize="2048",EepromSize="128",Speed="4",Message="Please use speed +1 or lower.";

Just strange that you have activity with one chip and not the other.
