解决
按照 https://segmentfault.com/a/1190000039929141
新增PPA的方式进行安装arm-none-eabi-gcc

sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa
sudo apt-get update
sudo apt-get install gcc-arm-embedded

出现错误

正准备解包 .../gcc-arm-embedded_7-2018q2-1~bionic1_amd64.deb  ...
正在解包 gcc-arm-embedded (7-2018q2-1~bionic1) ...

卸载 sudo apt-get remove gcc-arm-none-eabi

执行make，编译居然成功。。。。

至于原因，未知

更新： 重启终端后失效

需要源码安装版本 GNU Tools for Arm Embedded Processors 7-2018-q2-update ，更改/etc/profile 后重启生效，问题解决

2 安装openocd

sudo apt-get install openocd 

无错误

3 安装stlink

https://github.com/stlink-org/stlink  下载deb

安装 无错误

4 烧录bin文件

st-flash write ./build/你的目标文件.bin 0x08000000

出现错误

st-flash: symbol lookup error: /usr/lib/libstlink.so.1: undefined symbol: libusb_set_option

源码安装stlink 无错误
执行烧录，出现错误

st-flash 1.7.0
Failed to parse flash type or unrecognized flash type
2022-06-14T20:59:06 ERROR common.c: Can not connect to target. Please use 'connect under reset' and try again
Failed to connect to target

按住reset烧录，出现：

Unknown memory region

解决办法：需要额外给芯片供电

至此，踩坑完毕
