Building from Source

Prerequisites​

Follow the PX4 development environment setup for your OS. On Ubuntu:

bash ./Tools/setup/ubuntu.sh

You also need:

  • git
  • cmake 3.16+
  • python3 with pip
  • ARM GCC toolchain (installed by the setup script)

Clone PX4​

git clone https://github.com/PX4/PX4-Autopilot.git --recursive
cd PX4-Autopilot
note

The --recursive flag is required to pull all submodules including NuttX.

Build Firmware​

make avianautomata_305ap_default

The build output is at:

build/avianautomata_305ap_default/avianautomata_305ap_default.px4
build/avianautomata_305ap_default/avianautomata_305ap_default.bin

Use the .px4 file for QGroundControl or px_uploader.py. Use the .bin file for dfu-util.

Build Bootloader​

make avianautomata_305ap_bootloader

Output: build/avianautomata_305ap_bootloader/avianautomata_305ap_bootloader.bin

Other Build Targets​

make avianautomata_305ap_rover      # rover/ground vehicle variant

Modifying Kconfig​

To enable or disable drivers and features:

make avianautomata_305ap_default boardconfig

This opens the Kconfig menu. Changes are saved to boards/avianautomata/305ap/default.px4board.

Uploading After Build​

Via USB (if PX4 bootloader is present):

make avianautomata_305ap_default upload

Via DFU:

dfu-util -a 0 -s 0x08020000:leave -D build/avianautomata_305ap_default/avianautomata_305ap_default.bin
