help error at oxoooooo chip=0x04 buffer =0x04

[victorpro]

Clean the pcb and already the problem does not appear.
But divice id It recognizes
id=0xFF
0XFF
erase divice ok
read divice ok
blank check ok
program no functionally
Mistake appears error at 0x000000 chip 0xFF buffer 0x21
no can be programming .
It tries chip amic A29002IT
And it works ok
He forgives for my inglish
I speak the Spanish

[victorpro]

He does not identify chip
0x21
0xFF
read ok
erase ok
blank check ok
but It cannot programme
error at 0x000001 chip =0xff buffer 0x69
That means this?.
chip bad?
adapter PLCC-32_B2 bad ?
note:adapter dip 32 -A funtionally ok

[victorpro]

Which is the voltage in of reading and programming in pines 25.29.32.31 of adapter plcc 32 b2?

[Ezo]

What chips are tested with dip32a1 ? What chip ID are you getting ?
I suppose programmer failure, because no correct ID reply.
Go again Test H/W and check all signals one by one. Use check table, find in Guides.

[tps_star]

you can program other device with this programmer ?
or with other device have same problem ?
you sure your programmer working good ?

[victorpro]

Programme W49F002U WINBOND
A29002IT AMIC
With adapter dip 32a and I work ok.
But W39V040apz WINBOND with adapter plcc 32b does not detect ID .

Vcc 5v and not 4.3v in BU6/20 .

[tps_star]

if id not detect i think your chip is damaged
try with new chip
or is possible your adapter have problem and damaged chip

[victorpro]

but ready and erase chip ok

[tps_star]

blank check is ok ?
if is not your erase not ok

[victorpro]

yes, blank check is ok

[tps_star]

again try erase
after erase read chip and check checksum and buffer is empty
you use ezo4v4 or ezo4v5 ?
i think you try program new chip with this adapter
you have another adapter plcc_b2 ?

[victorpro]

use ezo4v4

[Ezo]

Seems programming works, but with random error.
If error reply chip 0xFF buffer 0x.., try overwrite.
Another options.
Remove temporary both capacitors 100n from plcc32b2.
Try with software 0.97d12c3

[victorpro]

tets whith capacitor removed

[victorpro]

In some ocacion it recognizes id but then already not.
