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.

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 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.
