使用vscode+openocd+telnet+arm-gdb编写stm32程序

记录自己在Linux中配置stm32编写环境的过程

安装好arm-tool-chains工具链

https://askubuntu.com/questions/1243252/how-to-install-arm-none-eabi-gdb-on-ubuntu-20-04-lts-focal-fossa

安装好openocd

安装好openocd以后去.bashrc文件中输入：

alias ocd="openocd.exe -f /usr/local/share/openocd/scripts/interface/cmsis-dap.cfg -f /usr/local/share/openocd/scripts/target/stm32f1x.cfg -c \"bindto 0.0.0.0\" "

安装好telnet

cat /etc/resolv.conf查看主机地址，不要使用localhost

安装好telnet：在.bashrc中

alias mytel="telnet  172.19.240.1 4444" 

由于我使用的是wsl，所以我在使用localhost的时候是无法正常工作的。而是要直接使用主机主机地址。

安装好vscode插件crotex-debug

配置好vscode

使用方法一

这个方法是直接在终端环境下进行调试的。

1. 打开一个终端，输入ocd打开openocd服务
2. 打卡另一个终端输出mytel，打开telnet服务
3. 打开第三个终端，使用arm-none-linux-gdb ./test.elf进行调试。在gdb中输入target remote 172.19.240.1:3333连接telnet，之后就可以进行调试了。

使用方法二

这种方法是使用vscode中的调试插件来进行调试
