39VF080 programming issue

[einsmman]

Hi!

I am programming chip 39VF080 with adapter TSOP40 A3. Everything is fine but after to programming when run the verification programming i have this error:

error at 0x010001 Chip = 0x14 buffer = 0x40

It's normal this error?

Regards.

Check line to pin A16, related chip pin soldering.

Hi again.

I checked pin A16 and everything is fine but I still get the same error:

error at 0x010001 Chip = 0x14 buffer = 0x40

Is it possible that despite this memory error has been recorded correctly?

Thank you very much by your replys.

PS. Is there any program that can edit two files (bin, rom) to compare differences between them?

What is get ID reply ?
Do you erase chip before write ? Run blank check.

I am using Hex Workshop.

Hi Ezo !!

I do the following:

SST39VF080
Adapter TSOP-40_A3
Type memory in Willem Eeprom software (0,97ja): Am29F080; Pin 2,5 in programmer pcb
ID: 0xBF SST/Sanyo (in file chip_test20.xls I read 00xBF; it's Ok?)
0xD8 SST39LF/VF080
Erase: OK
Blank Check: OK (device is empty)
Programming: OK
Verification programming: error at 0x010001 Chip = 0x14 buffer = 0x40

It's necessary check option "Temporary Sector Unprotect?

Thanks for your time

Programming: OK

Looks OK

Verification programming: error at 0x010001 Chip = 0x14 buffer = 0x40

Go to Buffer. What is content in adress 0x000000, 0x000001, 0x010000, 0x010001 ?
Run read and check adress 0x010001 content in buffer.
Load source file and verify chip content, is the same error ?
Try write another different file.
Try with 2.95V option, remove jumper Jp2.
Clean chip pins from flux.
Come back with info and results.

It's necessary check option "Temporary Sector Unprotect?

Not necessary. Option not supported for this chip.

Clean chip pins from flux.

It was the solution to the problem.

The simple operation of mounting the adapter on the programmer may be sufficient for a weak weld that does not make contact. I have happened to me

Thank you very much for all.
