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

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?

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?
