Burn1 issue

[WallyCJ7]

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?

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.
