Hello,
I've erased and blank checked M27V322 chips but every time I write to them (I used mulitple chips) I get the same error.

Write failed, address=0x200000, buffer=0x6E Device=0x24

J1 is on 1-2 shorted, J5 is shorting the right two pins. No other jumpers.
It would be nice if some where there was at least a list of device errors so I could work this out myself.

Anyone have a clue were I've gone wrong?

J1 should on lower two pins.

Thanks ZLM.
I did try that and I got a different error with 3 chips and just tried a 4th and it worked. Woohoo!

Could be bad chips but you can also try a slower speed.

Did the mod, tried slower speeds and got 1 and only 1 to work. Have ordered new chips.

Do you get the same error on all non working chips?

No, the errors varied. Makes me think it's more the chips than the programmer set up.

Probably. Where do they come from?

Absolutely no luck writing M27V322 chips. I've erased old ones, used new ones never written to, erased new ones, modded the unit as per the sticky posts with the address lines connected, USB power only, external 9V, latest updates on firmware, absolutely nothing I've done works since that one and only chip wrote and worked in the unit it was for.
Months of trying off and on and nothing.
Very, very frustrating!
Ready to put the programmer on ebay and try something else unless someone can give me some reason why I can't write to M27V322 chips.

Just looked at the datasheet, try with the write VCC set to 6.2V.

Is that a program setting or a jumper setting? There's nothing in th manual about it.
Why does a sticky post in this forum sa I need A21 connected from the unit to the adaptor board when V322 does have an A21?

Device setting. Yes it's in the manual section 6 or 2.6 online. Connecting A21 is standard procedure for this adapter but of course if a particular chip doesn't use it I don't think it would make any difference.

You legend! Finally it worked!
Will have to look into that when I have to program the M27V160 chips.

Edited txt file and still a big fat fail.



Do they pass the blank check?

I changed the wrong setting in the txt file. When I realised I rectified it and it worked perfectly.

Post your device line it may help someone else or even end up in the official devices.txt.

Here's the fix as worked out by anniel.
.
The A19, A20 and A21 address lines had to be connected from the main board to the adaptor board as per one of the sticky posts.

The tricky part was the devices.txt file had to be altered for the M27V322. User anniel pointed out the write voltage needed to be 6.2v as per the datacheet.

This is the altered line with the added text in red.
Name="M27V322",ID="XXXX",Class="27C322",Category="EPROM",MFG="ST",CodeSize="4194304",VCC="3.3V",Adapter="ADP-054, ADP-055 16 BIT EPROM ADAPTER"],WVCC="6.2v";

I may have to revoke your Legend status. Every chip has failed since that first one worked. May have just been a coincidence it worked.

Does the chips that fail pass the blank check? Is the ID correct?
You know there is also 6.5V you can try...

New?!? Where did you get those, they are out of production for quite some time now.

The ADP-054 on GQ-4x and GQ-4x4 do not need to connect A19,A20,A21,A22,A23 address lines. The adapter already has those connections to programmer. Unless you are using the adapter not from MCUmall.

The chip need to be erased completely with enough time. If the chip is not erased sufficiently, then the programming may fail on random location.

Change the programming WVCC may help for some EPROMs. IT can be set to 5V, 5.5V,6.2V,6.5V.

Also, change the J5 of adapter may help on those old EPROM's compatibility too.

I'm using GQ-4X and ADP-054
J5 done.
J1 set on 27C322.

The M27V322 uses same read/write algorithm as regular M27C322, except the reading voltage can be as low as 3.6V.

All operation should work as regular M27C322 as long as change the device reading voltage to 3.6V.

Tuco, if you still have problem with is chip, you can send a testing chip to MCUmall to confirm the problem. The chip can sent back to you after problem solved.

However, my feeling is the chip problem. May be related to incomplete erasing or over erasing.

anniel, thank you for all your replies. Can you send an email to support@mcumall.com too?

Working on the M27V160 chips now. One out of seven so far.

Older vintage chips and cutting edge chips are on each end of the bell curve for that.
