I have issues with the following programmer:

If I use this one

I get a working connection.

When measuring the voltages I get ca 5 on the black programmer and 3.3 on the green one.

The following page has possible workarounds for this issue:

I tried a spi-nor chip and that worked with 5V signalling. Maybe the spi-nand is more picky.
