• 安装.deb 只要输入“sudo dpkg -i 文件名”就可以了

Ubuntu中gcc-arm-none-eabi的安装

https://blog.csdn.net/qq_20016593/article/details/125343260

手动安装(推荐)

（1）官网下载：https://developer.arm.com/downloads/-/gnu-rm

pushd .
tar -jxf gcc-arm-none-eabi-6-2017-q2-update-linux.tar.bz2
sudo mv gcc-arm-none-eabi-6-2017-q2-update /opt
exportline="export PATH=/opt/gcc-arm-none-eabi-6-2017-q2-update/bin:\$PATH"
if grep -Fxq "$exportline" ~/.profile; then echo nothing to do ; else echo $exportline >> ~/.profile; fi
source ~/.profile
popd

• 检查交叉编译器是否安装成功

arm-none-eabi-gcc -v

设置arm-noneeabi-gdb

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

sudo ln -s /usr/share/gcc-arm-none-eabi-YOUR-VERSION/bin/arm-none-eabi-gcc /usr/bin/arm-none-eabi-gcc 
sudo ln -s /usr/share/gcc-arm-none-eabi-YOUR-VERSION/bin/arm-none-eabi-g++ /usr/bin/arm-none-eabi-g++
sudo ln -s /usr/share/gcc-arm-none-eabi-YOUR-VERSION/bin/arm-none-eabi-gdb /usr/bin/arm-none-eabi-gdb

st-link 安装

https://github.com/stlink-org/stlink/releases

• 根据日期选择适合自己版本的进行安装.

安装openocd

0. 安装依赖

sudo apt-get install build-essential pkg-config autoconf automake libtool libusb-dev libusb-1.0-0-dev libhidapi-dev
 
sudo apt-get install libtool libsysfs-dev

1. 克隆openocd 0.12.0源码

git clone git@github.com:openocd-org/openocd.git

2. 进入openocd目录：

cd openocd

3. git 子模块更新

git submodule init
git submodule update

4. 修改文件夹权限

sudo chmod -R +x openocd/

5. 修改换行符为LF

sudo apt-get install dos2unix
find /home/embedsky/share/openocd -type f -exec dos2unix {} \;

6. 运行编译脚本

sudo ./bootstrap

7. 进入jimtcl编译安装jimtcl

cd jimtcl/
sudo ./configure
make
sudo make install

8. 回到openocd根目录下执行

sudo ./configure

• 具有如下命令则编译成功

config.status: executing libtool commands

• 验证版本

openocd --version

• 执行开启GDB服务器

st-info --probe# 查看接入的st-link版本信息

• target/stm32f4x.cfg选择目标芯片适配的文件

sudo openocd -f /usr/local/share/openocd/scripts/interface/stlink.cfg -f /usr/local/share/openocd/scripts/target/stm32h7x.cfg

• 使用 telnet 登录到这个服务器

telnet localhost 4444

输入 halt 命令，芯片停止运行。

halt

输入 reset 命令，芯片复位重启。

reset

vscode 单步调试

• 编辑 tasks.json 文件，添加如下三个任务：
  1. openocd server：用于开启 openocd GDB 服务器。
  2. rebuild：用于重新编译工程。
  3. build：用于编译工程。

问题排查

1. Error: couldn’t bind tcl to socket on port 6666: Address already in use
   服务器未关闭,查找线程并杀除

netstat -tulpn | grep 6666
$ tcp        0      0 127.0.0.1:6666          0.0.0.0:*               LISTEN      65776/openocd 
kill 65776#PID号

# 或者
killall -9 openocd 

2. auto-selecting first available session transport “dapdirect_swd”. To override use ‘transport select ‘.Error: open failed

• 没有接入st-link,接入后尝试
• 先用st-info --probe确保正常连接
