Hello. I've checked v.11.70 and the problem still exists. Can you tell me if this problem will be fixed next version, or I have to go and buy another programmer?

Hello. Is it possible to solve my problem?

I've checked several flash chips. I think this is can't be a adress pin problem, because  can read flash wih any problem. Test for pin connection shows no error. Also, I get programm error immediatly when starting to program. I also noticed, that LH28F320BJE-PT and LH32F800BGE-B have different algorithms. The first uses Flash16bit , and the second NorFlash. May be this is the problem?

Carefully handle the connection of pins and socket pins.
First 512kbits is normal . so bad pins is A18/A19 address pins ?
