初始化配置
说明：我使用的MCU是stm32f103c8t6。
1. 在Arch Linux下配置开发环境
sudo pacman -S openocd stlink
安装完后，将板子、stLink下载器和电脑连接起来，注意：针脚一定要对应，否则会有烧坏风险。
验证：
st-info --probe
如果线没有插牢固：
$ openocd -f interface/stlink.cfg -f target/stm32f1x.cfg

Info : auto-selecting first available session transport "hla_swd". To override use 'transport select <transport>'.
Info : The selected transport took over low-level target control. The results might differ compared to plain JTAG/SWD
Info : Listening on port 6666 for tcl connections
Info : Listening on port 4444 for telnet connections
Info : clock speed 1000 kHz
Info : STLINK V2J37S7 (API v2) VID:PID 0483:3748
Info : Target voltage: 3.244890
Error: init mode failed (unable to connect to the target)
正常输出：
$ openocd -f interface/stlink.cfg -f target/stm32f1x.cfg

2.使用stm32cubemx创建工程
可以便捷地使用yay安装。
yay -S stm32cubemx
打开无响应，发现报错？
# 可供参考的命令
sudo pacman -S archlinux-java-run
archlinux-java status
sudo archlinux-java set [填入你上一条命令得到的jdk名称]
找到MCU型号创建工程后，按图示设置引脚：

在左侧边栏的System Core这里将如图所示的选项勾选：
像图中那样配置时钟：
