I am having issues programming 25c040's using the willem enhanced programmer. Is there anything in particular to these? I'm using 0.97ja

I cannot get it to write correctly, it will read correctly, but not write. Incidentally if I select 25c020 it will program the first 256 bytes with no problems, but it won't do it correctly using 25c040.

It seems the software bug.

So is there a fix, or a version that works?

I have already tried that, even older versions. I need to progam these, but I'm afraid of buying another willem programmer if the issue is with the software.

True-USB willem supports 25040 SPI EEPROM too.
