Loading Firmware

Note,upload firmware should use micro USB cube line, do not use radio telemetry to upload.

Connect flight controller to computer

Once you’ve installed a ground station on your computer, connect the flight controller using the micro USB cable as shown below. Use a direct USB port on your computer (not a USB hub).Pixhawk USB Connection

Windows should automatically detect and install the correct driver software.

Select the COM port

If using the Mission Planner select the COM port drop-down on the upper-right corner of the screen (near the Connect button). Select specific port (do not select AUTO)for your board (PX4FMU or Arduino Mega 2560). Set the Baud rate to115200 as shown.

If you can not detect the COM port ,maybe your board driver is not installed, please install it.

Next you may be asked “Upload ChibiOS?”. Most users will not notice a significant difference regardless of how this is answered.

  • “Yes” will load ArduPilot using the newer ChibiOS operating system which results in a smaller and more efficient firmware but has a few missing features
  • “No” will load ArduPilot using the older NuttX operating system.

Note,

  • If you click Yes to upload the ChibiOS firmware, after that, the COM port will be diffrent with before, you should select the right COM port.
  • IF you upload the chibiOS firmware, maybe you will meet PC driver problem,You can use the WIN10 system.

If all goes well you will see some status appear on the bottom right including the words, “erase...”, “program...”, “verify..” and “Upload Done”. The firmware has been succesfully uploaded to the board.

After Upload

click "DATA" and goto this page,then reboot the board.

Do not at "INSTALL SETUP/Install Firmware" to reboot the board.

Why?when the Mission Planner screen is at "INSTALL SETUP/Install Firmware", if you insert PIXHAWK to your PC, the pixhawk will goto bootloader mode.Resulting in an inability to connect.
