Arjan - PD3SPY
I'll try this next time I'm able to spend time at the hobby! Now away for work cor a few day ): thanks for the tip!
I have a board version with 2x3 pin header. Placed both jumpers on pin 2+3. Looking at the schematics this should be correct. Although unlikely, I might change my jumpers out for new one next time over to rule out any faults. Solder joints I have already checked...
Thanks all for the tips and help. Will try when I get back from work!
