Burn1 issue

Today I trying to work on tuning and I'm thinking the Burn1 is not working.

Start Flash & Burn

27SF512 highlighted
Chip address set to Start: 00F000 End: 00FFFF
Buffer address: start 000000 end 000FFF

Erase chip - Erase Succeeded
Blank check - Chip is blank

I load file to buffer... it shows C:\......asdu05.bin file size in bytes (integer/Hex): 4096/0x1000

Program chip...Prom I/O succeeded.

Verify chip with buffer.... Failure: Verification failed (not matched)

Blank check... Chip is blank.

I've tried it with different .BIN files and it always the same.

I've rebooted the computer, used a different computer and its always the same...

2 different chips used
??? Burn1 gone bye bye?:mad1:

The first thing that comes to mind is whether you are placing the EEPROM in the ZIF socket correctly. Pin 1 towards handle, but the IC placed in the slots farthest away from the ZIF socket?

Notch towards the arm and set furthest away from the arm

You are burning 4k file size? Just double checking

I've found a broken solder joint or two with my BURN2's socket that requires me to shift a PROM around slightly in the socket for a program to be successful, you might be dealing with a similar problem.

Are you saying side to side or a different set of slots? I'll try side to side.

Yes 4k and I've tried 256k too

No luck side to side... I moved it like 5 times.

usually, once I have the PROM locked down, if it gives me issues, i'll move it slightly to one side without unlocking it, try it, if it still doesn't work, I move it towards the other side.

if it still doesn't work at that point, slight pressure pushing the chip into the socket, one end usually does the trick.

I really just need to open it up and resolder all 32 pin connections though.

I found the problem. I took the chips to the local Dyno shop and they have a burn2. He tried to load my BIN file and has the same results on both chips.
He pulled out one of his chips and the BIN file wrote to his just fine...

So somehow I have two bad chips. That seems kind of funny to have two chips both bad. :innocent2:
I just got them last month so I will be calling Moates tomorrow to see what the issue cold be.

At least it not the burn1 or did it cause the problem with the chips? I'll order extra chips, $5 is cheep insurance to me...
