环境安装

注：文末提供一键脚本

stm32cubeclt_6">下载安装stm32cubeclt

下载地址为：https://www.st.com/en/development-tools/stm32cubeclt.html

选择 linux版本下载安装

在这里插入图片描述

安装好后默认在家目录st下

> $ ls ~/st/stm32cubeclt_1.16.0

stm32cubemx_25">下载安装stm32cubemx

下载地址为https://www.st.com/en/development-tools/stm32cubemx.html

同样下载安装linux版本，安装好后默认在~/STM32CubeMX

开发调试

1. 工程初始化

使用cubemx随意生成一个cmake的测试工程，进入到工程目录

cd balance-car  #balance-car为我测试工程文件夹
export PATH=$PATH:$HOME/st/stm32cubeclt_1.16.0/GNU-tools-for-STM32/bin
mkdir build && cd build
cmake ..

2. 工程编译

继续在build目录执行make命令

make

出现以下内容表示编译成功

Memory region         Used Size  Region Size  %age Used
             RAM:        2928 B        20 KB     14.30%
           FLASH:       53928 B        64 KB     82.29%
[100%] Built target balance-car

编译好后的二进制名为balance-car.elf

3.工程下载

执行以下命令下载程序

 ~/st/stm32cubeclt_1.16.0/STM32CubeProgrammer/bin/STM32_Programmer_CLI --connect port=swd --download ./balance-car.elf -hardRst -rst --start

下载成功提示输出：

4.工程调试

启动gdbserver

打开一个新的命令窗口进入以下目录

cd ~/st/stm32cubeclt_1.16.0/STLink-gdb-server/bin/

修改此目录下config.txt 中-cp字段，注意需要将home后yala字段修改为自己对应家目录名称

###############################################################
#  -cp <path>         : Path to STM32CubeProgrammer
#                       Modify to correct path
#                       for STM32_Programmer_CLI executable
###############################################################
-cp /home/yala/st/stm32cubeclt_1.16.0/STM32CubeProgrammer/bin

此修改只进行一次，修改完成后启动gdb

./ST-LINK_gdbserver -c config.txt

启动成功输出如下

STMicroelectronics ST-LINK GDB server. Version 7.8.0

开始调试

回到build目录，启动gdb

~/st/stm32cubeclt_1.16.0/GNU-tools-for-STM32/bin/arm-none-eabi-gdb balance-car.elf

在gdb中连接到gdbserver

(gdb) target remote localhost:61234
Remote debugging using localhost:61234
Reset_Handler () at /home/junchao/work/balance-car/startup_stm32f103xb.s:64
64          bl  SystemInit

到这里就可以正常开始下断点调试了

EXT：方法2

从第三步开始，可以使用stlink开源工具实现程序下载、调试

从https://github.com/stlink-org/stlink/releases下载最新deb安装包，安装

sudo dpkg -i ./stlink_1.8.0-1_amd64.deb

启动gdbserver

st-util

成功输出为

st-util 1.8.0
2024-11-15T15:40:21 INFO common.c: NRST is not connected --> using software reset via AIRCR
2024-11-15T15:40:21 INFO common.c: STM32F1xx_MD: 20 KiB SRAM, 64 KiB flash in at least 1 KiB pages.
2024-11-15T15:40:21 INFO gdb-server.c: Listening at *:4242...

下载调试

回到build目录，执行改变

~/st/stm32cubeclt_1.16.0/GNU-tools-for-STM32/bin/arm-none-eabi-gdb balance-car.elf

在gdb中连接到gdbserver

(gdb) target remote localhost:4242
Remote debugging using localhost:4242
main () at /home/junchao/work/balance-car/Core/Src/main.c:74
74        uint32_t loop_cnt = 0;

现在即可开始调试。若重新编译二进制后可以使用load命令下载更新程序

(gdb) load balance-car.elf
Loading section .isr_vector, size 0x10c lma 0x8000000
Loading section .text, size 0xbe54 lma 0x8000110
Loading section .rodata, size 0x1108 lma 0x800bf68

Start address 0x0800b31c, load size 53920

一键脚本

编写了一个脚本用于一键操作

将脚本放到工程根目录（勿放到build目录），cubemx生成的工程文件夹名称不能修改，脚本依赖它运行

使用示例

./st-tool build  #编译项目
./st-tool dbg  # 启动调试
./st-tool dbg load # gdb启动后先进行程序下载操作再进行调试
./st-tool flash # 下载程序

请注意修改脚本中$HOME/st/stm32cubeclt_1.16.0路径

#!/bin/bash

export PATH=$PATH:$HOME/st/stm32cubeclt_1.16.0/GNU-tools-for-STM32/bin/
