pixhawk控制板的ArduPilot固件编译

0. 环境

- ubuntu18（依赖python2和pip，建议直接ubuntu18不用最新的）
- pixhawk 2.4.8
- pixhawk 4

1. 获取源码

# 安装git

sudo apt install git

# 获取源码

cd ~/work
git clone --recurse-submodules https://github.com/ArduPilot/ardupilot
cd ardupilot

# 如果初次没顺利克隆子仓库，则：

git clone  https://github.com/ArduPilot/ardupilot
cd ardupilot
git submodule update --init --recursive

# 压缩源码备份

cd ~/work
7z a ardupilot_git_src_20240317.7z ardupilot

2. 安装依赖

$ ./Tools/environment_install/install-prereqs-ubuntu.sh
Install ArduPilot STM32 toolchain [N/y]?N

3. 安装交叉编译工具链

下载

https://firmware.ardupilot.org/Tools/STM32-tools/gcc-arm-none-eabi-10-2020-q4-major-x86_64-linux.tar.bz2

可以到这里浏览版本：

https://firmware.ardupilot.org/Tools/STM32-tools/

解压

tar -xjvf gcc-arm-none-eabi-10-2020-q4-major-x86_64-linux.tar.bz2

设置环境变量

export PATH=$PATH:/home/xxjianvm/work/gcc-arm-none-eabi-10-2020-q4-major/bin

4. 编译

# 设置环境变量

export PATH=$PATH:/home/xxjianvm/work/gcc-arm-none-eabi-10-2020-q4-major/bin
export PATH=$PATH:/home/xxjianvm/work/ardupilot/Tools/autotest
export PATH=/usr/lib/ccache:$PATH
source /home/xxjianvm/work/ardupilot/Tools/completion/completion.bash

# 配置

./waf list_boards
./waf configure --board fmuv3          # 3DR Pixhawk 2 boards
#./waf configure --board fmuv5          # Pixhawk 4

# 编译

./waf clean
#./waf rover
#./waf copter 

 

 

# 上传

./waf --targets bin/ardurover --upload

5. 问题集锦

问题：/usr/bin/python3: can't open file '/home/xxjianvm/work/ardupilot/modules/DroneCAN/dronecan_dsdlc/dronecan_dsdlc.py': [Errno 2] No such file or directory
分析：网络不好，浏览发现dronecan_dsdlc是空的
解决办法：把文件夹 dronecan_dsdlc 删除，再次执行 git submodule update --init --recursive

问题：dronecan_dsdlc.py: error: the following arguments are required: namespace_dir
分析：发现DroneCAN下的DSDL、libcanard又是空的
