use slower speed.

I already did, but it always gives an error in the verification.

I recommend you to remove the chip from PCB and put it in the adapter to read and write.

That way is the standard programming way.
brchip Posted - 06/27/2010 : 04:40:09
Tried both ways. Reads and writes but verifiy gives error.

I tried 8 bit and 16. Is there a way to know which is the correct?

Are you doing it while the chip on the PCB?

Same here. I'm usng 3M clip with sw v4.01. Should I upgrade to the latest sw?

I tried different speeds and devices (8 and 16 bits) but no luck.

Any ideas?

I'm having the same problem. I'm using 3M soic8 clip. I used this clip for other chips and it worked fine.

Please help.

What adapter you used?
Check pin contact.
