Hi Fabian,
sure I used my multi-meter to test connectivity before I sent my message and I also have? the FCI chip.
Please have a look onto attached picture, which shows my Raduino board. You can clearly see that both pins are connected (under solder mask). As far as I remember this was also the case with the first Raduino for BITX40. It may be confusing, but for sure it has nothing to do with your problem.
Are you using Memory Manager?
Regards
Armin
