I built it using “Building ArduPilot using Waf build system”.
I connected to missionplanner.
sudo ./ardupilot/build/navio2/bin/arducopter -A udp:192.168.2.108:14550
Raspberry Pi 3 Model B Rev 1.2. (intern: 2)
MS5611 found on bus 1 address 0x77
MPU: temp reset IMU 5881 3632
I finished the calibration, but the LED of Navio 2 is blinking yellow and it can not be armed.
I do not know the cause, please help me.
