Linux 开发环境
在Linux下和STM32F1xx的开发环境是一样的, 可以使用 gcc-arm 编译, 用 st-flash 烧录. 开发库可以使用 SPL, 或者 Libopencm3.
安装 st-flash
首先检查一下系统中是否有st-flash和st-info命令, 没有的话需要安装
安装步骤
git clone https://github.com/stlink-org/stlink.git
cd stlink/
make
# 如果报 libusb 错误, 就安装一下 libusb-1.0-0-dev, 再make
sudo apt install libusb-1.0-0-dev
make clean
make
cd build/Release/
sudo make install
如果运行 st-info 出现下面的错误
st-info: error while loading shared libraries: libstlink.so.1: cannot open shared object file: No such file or directory
运行一下sudo ldconfig可以解决问题
将 AIR32F103 通过 stlink 接上PC后, 可以通过 st-info 查看信息, 似乎并不能正确识别, 但是无所谓, 能检测到就可以了
~$ st-info --probe

Update 2022-07-23: 检测同一型号贴在bluepill核心板上的 MH32F103ACBT6 识别的结果和 AIR32F103 还不一样, 输出是这样的
$ st-info --probe

Libopencm3 项目模板
项目模板: https://github.com/IOsetting/libopencm3-freertos-template
- 安装 GCC ARM
在GCC ARM网站下载工具链接https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/downloads, 然后解压到合适的目录
tar xvf gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2
cd /opt/gcc-arm/
sudo mv ~/Backup/linux/gcc-arm-none-eabi-10.3-2021.10/ .
sudo chown -R root:root gcc-arm-none-eabi-10.3-2021.10/
检查版本
/opt/gcc-arm/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-gcc --version
- 导出项目
git clone --recurse-submodules https://github.com/IOsetting/libopencm3-freertos-template.git your-project
如果导出子模块过程中出错了, 可以在项目目录下运行下面的命令修复
git submodule update --init
因为AIR32F103CBT6配置比C8T6高一规格, 需要修改下Makefile, 将 DEVICE 设成 stm32f103cbt6
DEVICE = stm32f103cbt6
- 编译 Libopencm3
cd your-project
PREFIX=/opt/gcc-arm/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi- make -C libopencm3
- 编译项目
PREFIX=/opt/gcc-arm/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi- make -C user
FreeRTOS例子的编译
如果编译带 FreeRTOS 的例子, 会提示错误fatal error: FreeRTOSConfig.h: No such file or directory,
编译需要带上选项FREERTOS=1
PREFIX=/opt/gcc-arm/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi- FREERTOS=1 make -C user
- 烧录
st-flash --reset write user/app.bin 0x8000000
正常烧录的输出
st-flash 1.7.0-201-g254a525
