I am trying to get ArduCopter running on Mamba H743 MK4, but run into various issues. For instance, it doesn’t detect the barometer and fails. The FC itself is not defective and works fine with iNav. As I know, different versions of this board have different hardware. Mine has the SPL06 barometer according to iNav: https://imgur.com/a/DdrTxgQ
Additionally, the Mission Planner hangs when trying to calibrate accelerometer, then disconnects and can’t connect again with the “Connect Failed” error until I reboot the FC. Log: https://imgur.com/a/0BUvROC
Is my FC supported by ArduCopter? And if so, how do I get it to work? Can you manually select the barometer type somewhere in the settings or is it hard-coded for each FC?
Additionally, I am experiencing some heavy connection issues. I have to reconnect the USB cable or restart the programs multiple times before I can finally connect to the FC via Mission Planner or MAVProxy:

One thing to note. These boards are known to have power issues when running on USB - in particular there is often not enough power on i2c if you have other things connected. If you are only testing on USB it is worth connecting a battery to see if the problem goes away.
