Can you confirm the chip can be erased? If it can be erased, then the write should work.
OR
The chip is sector locked?

Since you can ID correctly, then the chip has correct position and correct setup. A19 must be connected.

I would like you to try:
1. not use the external power.
2. set the adapter vcc jumper to 5V when you specifiy the vcc="3.6V" in the devices .txt.
3. set the adapter vcc jumper to 3.6V when you specifiy the vcc="5V" in the devices .txt.
4. after write failed, do a blank check to see if the whole chip still blank.

yes A19 is everytime connected and i get correct id.
after write fail, i can see the first 10 line are written with 02
and the rest is with ff.

external power was just for testing,normally i dont use it!

with the new chips i get the id "02" but all pins are clean and at right position

do you have SST39VF080 for testing?
what can i do?

I carefully checked the TSOP40A-DIP32 adapter, but did not find anything wrong. All signals are correctly assigned and working fine.

You said the chip been written with 02 and rest with ff. Then it seems the software need to be checked. I will review the software and may post a testing patch for you later. If possible, please send me a testing chip. So that to completely find out the reason. I will send back the testing chip to you.

yes the tsop40a adapter is working fine,because i programmed today a am29lv008bt and a mx29lv008ct without problems,you know they use same adapter an a19 cable to!

the 02 which i mean is correct,because if open my bios image with your software and code,it shows upto Offset 00000FF0 only 00 02 00 02.....
after this line there are asci codes.

but the programmer writes only 10 lines and then it breaks operation

Can you post your device line for this AM29lv008BT you used?


Do your means the first 10 line are correct on SST29VF080?

try this patch, extract to the "C:\Program Files\GQ USB Programmer", overwrite the old version.

i posted the corect line for AM29lv008BT as new topic.
after trying and trying ,iwas able to write the chip up to 18% (the patch didnt help).

only with this line
Name="SST39VF080",ID="BFD8",Class="SST39LF/VF040",Category="FLASH",MFG="SST",CodeSize="1048576",DIP="100011110101",Adapter="TSOP40A-DIP32",VCC="5V",Message="close all jumper and connect the A19 from adapter to programmer";

if i try to open vcc jumper or add vcc 3v6 in devices,then it wont write...all my SST39VF080 are so!
and this error came:

I seems the adapter hardware related.
Did you try the slower speed on patch? Speed 0 or -2?

If software can not fix, then I need a testing chip to find out a solution.

Found the final fix solution on TSOP40A board. It uses a 74HC244 chip for the signal enhancement. No extra capacitor on adapter.
one trace cut needed see picture.

The software works fine on Re4.02 release. No patch needed.

This fix should not affect any other chips supported on this adapter.

great,thank you very much!
i know the picture is very good,but i dont want mistake ,so my question is:

cut "CE" connection from tsop-board near "A1" label and connect a cable from the left side "CE" near "A1" label with pin7 from 74hc244.

connect "GND" from board with pin10 an pin19 from 74hc244.

connect pin20 from 74hc244 with "VCC".

connect pin13 from 74hc244 with "CE" on the right side.

can i use 74hct244 if dont find your ic?
best regards.

Yes. Your are right.
Basically the 74HC244 is only to enhance the CE signal. The CE signal from programmer will go through the 74HC244 and then out put to the TSOP40 pin 9 WE. So, we cut the CE signal and insert the 74HC244 in the CE signal.

The 74HCT244 should work too.
