Hello Frank,

Thanks for replying.

I don't know why that option doesn't appear.

I downloaded the stand-alone programmer and I get exactly the same problem.

Do you know if that option appears only when it recognises the config chip ?

When I want to change mode I just move the switch to PROG, then do an autodetect.

Is that correct ?

At the moment I'm using .jic files and SFL to config the chip - that works without

any problem.

It doesn't look to me like a hardware problem - I wonder if there's a non-default

setting which needs to be changed somewhere.

Best
