I just bought a Holybro Pixhawk Mini and tried to load Arducopter 4.07. The firmware update seemed to go as it should but when I tried to connect, I get an audio error message that says to "Check BRD_TYPE. Could not update IO firmware. When I checked the BRD_TYPE setting I find there is no listing for the Pixhawk4 Mini, It shows just about every other Pixhawk available except the one I just spent $200 on. Any Ideas?
