BetaFlight是一款非常出色的飞控航模开源软件，而且是基于GPL V3协议，所以相应的代码修改，必须开源出来。与PX4的BSD协议不一样，通常商业角度更多倾向于BSD协议。
本次编译主要是针对AOCODARC-F7MINI飞控板，采用最新的代码分支进行编译，以便进行功能验证。

2. 编译步骤
Step 1 软件配置环境准备
这里基于Ubuntu准备相关的软件配置环境。
$ sudo apt-get update
$ sudo apt-get install git
$ sudo apt-get install gitk git-gui
$ uname -a

$ lsb_release -a

Step 3 构建命令介绍
在betaflight目录下，直接敲make help，脚本会显示命令所支持的参数。
这个还是非常C的工程，应为他采用了Makefile。不过作为用户就不要去研究里面的东东了。而且也没必要耗费大量的时间去构建所有目标板的固件，我们只需要确认并编译自己硬件的固件即可。
$ make help
Makefile for the betaflight firmware
Usage:
make [V=<verbosity>] [TARGET=<target>] [OPTIONS="<options>"]
Or:
make <target> [V=<verbosity>] [OPTIONS="<options>"]
Valid TARGET values are: SITL STM32F405 STM32F411 STM32F745 STM32F7X2 STM32G47X STM32H723 STM32H730 STM32H743 STM32H750
V : Set verbosity level based on the V= parameter
V=0 Low
V=1 High
compile_file takes two arguments: (1) optimisation description string and (2) optimisation compiler flag
all : Build all currently built targets
all_all : Build all targets (including legacy / unsupported)
clean : clean up temporary / machine-generated files
test_clean : clean up temporary / machine-generated files (tests)
<TARGET>_clean : clean up one specific target (alias for above)
clean_all : clean all valid targets
<TARGET>_flash : build and flash a target
tty_flash : flash firmware (.hex) onto flight controller via a serial port
dfu_flash : flash firmware (.bin) onto flight controller via a DFU mode
st-flash : flash firmware (.bin) onto flight controller
<TARGET>_zip : build target and zip it (useful for posting to GitHub)
<TARGET>_rev : build target and add revision to filename
unbrick : unbrick flight controller
cppcheck : run static analysis on C source code
version : print firmware version
help : print this help message and exit
targets : print a list of all valid target platforms (for consumption by scripts)
target-mcu : print the MCU type of the target
targets-by-mcu : make all targets that have a MCU_TYPE mcu
targets-f4 : make all F4 targets
targets-f7 : make all F7 targets
test : run the Betaflight test suite
junittest : run the Betaflight test suite, producing Junit XML result files.
test-representative: run a representative subset of the Betaflight test suite (i.e. run all tests, but run each expanded test only for one target)
test-all: run the Betaflight test suite including all per-target expanded tests
test_help : print the help message for the test suite (including a list of the available tests)
test_versions : print the compiler versions used for the test suite
test_% : run test 'test_%' from the test suite
arm_sdk_install : Install Arm SDK
arm_sdk_clean : Uninstall Arm SDK
Step 4 构建命令准备
编译之前首先需要安装编译工具。各地的网络情况不一样，所以下载会遇到失败，请耐性尝试。
$ make arm_sdk_install
mkdir -p tools
mkdir -p downloads
Warning: Illegal date format for -z, --time-cond (and not a file name).
Warning: Disabling time condition. See curl_getdate(3) for valid date syntax.

$ make arm_sdk_install

100 149M 100 149M 0 0 215k 0 0:11:51 0:11:51 --:--:-- 298k
注：有的时候会出现本地编译器版本太低的情况，需要执行上面的arm_sdk_install进行工具升级安装。
$ make targets
make/tools.mk:270: *** **ERROR** your arm-none-eabi-gcc is '10.2.1', but '10.3.1' is expected. Override with 'GCC_REQUIRED_VERSION' in make/local.mk or run 'make arm_sdk_install' to install the right version automatically in the tools folder of this repo. Stop.
Step 5 厂家目标板查询
当前手头硬件板子是否在BetaFlight的支持列表中，查询方式如下：
$ make targets
Valid targets: SITL STM32F405 STM32F411 STM32F745 STM32F7X2 STM32G47X STM32H723 STM32H730 STM32H743 STM32H750
Built targets: SITL STM32F405 STM32F411 STM32F745 STM32F7X2 STM32G47X STM32H723 STM32H730 STM32H743 STM32H750
Default target: STM32F405
鉴于产品规格：“控制器：STM32H722RET6”，所以在编译时需要选择“STM32F7X2”
Step 6 目标固件编译
BetaFlight在飞控代码上是基于MCU选型来区分目标代码，而相应的硬件配置通过unified-targets进行配置。
注：这是一种系统角度的软件代码设计思想，是非常好的设计思路，值得学习和借鉴！

make[1]: Leaving directory '/home/daniel/Work/betaflight'
Building STM32F7X2 succeeded.
此时已经生成./obj/betaflight_4.4.0_STM32F7X2.hex固件，可以采用configurator进行烧录。
Step 7 目标固件清理
有的时候可能调整了配置，甚至改动了代码，不采用增量式编译(防止有些改动没有起到效果)而希望全新编译固件。
