Hello I have problems writing to p28f001-bx-t120.
To read I use a resistor between pin 1 and 30. But I can not write to the memorie.
Programmer GQ-4x
Software Re. 5.03 Beta
It does seem to write but it does not pass the verificacion and actually nothing is writen to the memorie.
Thanks for help

I also have problems erasing the 28f001. It sends a message that says function not supported and I need to disconnect the programmer and reconnect to make it work again.
Thanks for help
