PX4 Bootloader Update

Before PX4 firmware can be installed, the PX4 bootloader must be flashed. Download the gearup_airbrainh743_bootloader.bin bootloader binary and read this page for flashing instructions.

Building Firmware

To build PX4 for this target:

make gearup_airbrainh743_default

Installing PX4 Firmware

Firmware can be installed in any of the normal ways:

Build and upload the source:

make gearup_airbrainh743_default upload

Load the firmware using QGroundControl. You can use either pre-built firmware or your own custom firmware.

Debug Port

System Console

UART1 (ttyS0) is configured for use as the System Console.
