Hi ALL
recently I purchased from MCUmall GQ-4X programmer with PSOP44-DIP ADP-019 adapter basically to have possibility to read/flash 28F400 flash chips.

And my first try is not successful - I can read 28f400, but I can't write to it :(

I also tried to burg few different 28F400 - the same result :(

What I'm doing wrong?

My log is:

Ready
H/W Re: GQ-4X Re-2.00
USB Driver Re.2.0
Software Re. 6.17
Checking new software on server...
This software is updated already.
<<AB28F400BX-B*PSOP44>>
Speed = 3
ID check OK
Writing... Code
Elapsed time: 9.20 seconds.
Device write completed OK
ID check OK
Verifying... Code
Verify Failed, Address=0x000001, Device=0x00, Buffer=0xFF
Verify Failed
Elapsed time: 6.18 seconds.


P.S. Before writing I filled buffer with FF to erase the flash content.
I also tried to write not FF from buffer, but real content - no success :( The same verification error at the first different data position...

I tried to burn with with external +9V power adapter connected to programmer, as well as without - no difference :(

Thanks in advance for any ideas!

Regards,

ZRimas

Fill the FF and write does not erase the chip. You need to click on the Erase button to erase the chip.

Do a blank check before write new data.

Try to use slower speed and wait to programmer VCC goes off.
If it stay forever, then your chip may have problem. Change to another known good chip.

Tried on different pc, different OSes, different USB cables and different chips. The same chips which can not be erased and flashed on my programmer, have been flashed on BeeProg in few seconds!

Thanks. I think this chip algorithm can be retested once got the testing chip.

? It means it's not my or chip problem, just you have to re-test the chip algoritm for this programmer. Do I understand it right?

Sorry. I means if you can send us your chip, we can test it for you.

This software algorithm is tested and works for years.

OR you can try on another known good chip.

OMG! Guys, do you really listen and read, what I wrote here and by e-mail? The same chips which can not be to erase/flash on GQ-4X, have been erased/flashed and tested on BeeProg in few seconds and working - that means, chips are not the problem. The problem is that you did not tested the algorithm for this chip (this is what you wrote few days before)!!!! I bought this programmer specially for 26f800 and because you are not China producer. I paid more, I waited longer with hope that this programmer will be much better than Chinese and I will have real support in case of problems... And now? I have programmer, which does not do the job it has to do, I'm writing letters and stories here and by email, trying to clear, what is wrong, every time I need to flash 26f400, I have to drive to my colleague, spend few hours for the travel, pay for the job... Nice, isn't?






BTW, just few minutes ago I tried to read/erase/flash AM29F400BT flash chip - everything is ok. That means, adapter is also OK - it's the same like for 28F400...

I tested with my chip and it works fine:

=======================================

Check your adapter jumper settings.
Jumper 1 on right 28F side.
Jumper 2 on 5V position.

If it still does not work, then send me your chip, we can find out the problem and fix it for you.

This chip in the confirmed list for a long time already, so far has no one complain. It may be related to the chip compatility issue.

OMG! Guys, that's really confirms that before using any device please read the f***g manual!

My apologies to mcumall for everything I wrote - that's my foul. Information on the adapter I red but understood it as I liked it...

Jumper now is in 28F position and everything is working!!!

Thanks a lot ZLM and one more time - my big sorry!

Topic closed. Problem solved.

There are many possibilities can cause this problem.

1. make sure you chip is a good working chip.
2. make sure you placed the chip in a correct position in adapter.
3. make sure your adapter is placed correctly.
4. make sure your chip pins are good,clean and have good contacts with adapter.
5. confirm your programmer is working good on all other chips.
6. ...
