I just tried to upgrade from 3.6.9 to 3.6.10 but after restarting the ardupilot service can’t connect to with MP and in the log on raspberry I can see only this:
/home/erle/PXFmini/ArduCopter-quad: /lib/arm-linux-gnueabihf/libm.so.6: version `GLIBC_2.27’ not found (required by /home/erle/PXFmini/ArduCopter-quad).
Do I need update my OS from Erle according to use latest build 3.6.10?
