I’m having some issues trying to program my pixhawk 3 pro with arducopter firmware. For verification I used QGroundcontrol (On windows) to install PX4 firmware which worked.
What i’ve tried:
Using QGroundcontrol -> install firmware -> APM Stack. The dropdown menu is empty, so I choose advanced settings, and use custom arducopter firmware downloaded from firmware.ardupilot.org (ArduCopter-v4pro.px4, last stable version, as well as the newest). It programs the board and it seemingly goes ok. When I cycle power on the autopilot, there communication possible (no telemetry data) other than reprogramming the device. The LED on the PWM output side does not light up.
I tried to install through Mission Planner as well, both with custom firmware and automatically downloaded firmware. They both go through the firmware install, and say to wait for a ‘beep’ which never occurs then press ok. If I press ok regardless, the board will not connect through the COM port (same as QGroundcontrol) but I can reprogram the device.
Any suggestion as to what might cause this? I googled abit, and I saw a thread with pixhawk 3 pro support from late 2017 so it should be in the stable version of arducopter now?
