I finally build wiringPi by myself and after that openplotter-Pypilot works correctly in compass only mode. now, my system is fully functional over Raspi-OS64.
For the VNC by now x11VNC does the job correctly and my RealVNC phone APP works perfectly with X11VNC. All mounted on a 128Gb Sandisk extreme gold SD... quite happy.
