I am sorry if this is necro posting but i am having a hell of a time with this ZIF socket and Nuvoton IC's. I have a NPCE48AL and this guy just refuses to read it. the firmware I have from a working board for this chip (bin) is 256 - so I keep trying with 256 config but no luck. Is there anything you can think of? Do these ZIF sockets or debug boards have nuvoton requirements?
