Pixhawk's binaries for ERB protocol compatibility

Hi people,

I’m having trouble uploading the custom firmware for ERB protocol in Pixhawk, as described in
https://docs.emlid.com/reach/apm-integration/

I installed ArduCopter-quad-v3.3.3-ERB.px4, but after that I get an error when trying to connect with a 3DR radio.

The error details are as follows:

em System.IO.Ports.InternalResources.WinIOError(Int32 errorCode, String str)
em System.IO.Ports.SerialStream.set_DtrEnable(Boolean value)
em System.IO.Ports.SerialStream…ctor(String portName, Int32 baudRate, Parity parity,
Int32 dataBits, StopBits stopBits, Int32 readTimeout, Int32 writeTimeout, Handshake handshake,
Boolean dtrEnable, Boolean rtsEnable, Boolean discardNull, Byte parityReplace)
em System.IO.Ports.SerialPort.Open()
em MissionPlanner.Comms.SerialPort.Open() na C:\Users\michael\Source\Repos\MissionPlanner\ExtLibs\Comms\CommsSerialPort.cs:linha
88
em MissionPlanner.MAVLinkInterface.OpenBg(Object PRsender, Boolean getparams, ProgressWorkerEventArgs
progressWorkerEventArgs) na C:\Users\michael\Source\Repos\MissionPlanner\Mavlink\MAVLinkInterface.cs:linha
548
em MissionPlanner.MAVLinkInterface.FrmProgressReporterDoWorkAndParams(Object sender,
ProgressWorkerEventArgs e, Object passdata) na C:\Users\michael\Source\Repos\MissionPlanner\Mavlink\MAVLinkInterface.cs:linha
355
em MissionPlanner.Controls.ProgressReporterDialogue.RunBackgroundOperation(Object
o) na C:\Users\michael\Source\Repos\MissionPlanner\ExtLibs\Controls\ProgressReporterDialogue.cs:linha
108

Would appreciate any help!
Have a great day :slight_smile:

Solved.
