准备工作

平台：Windows11（Linux，MAC同理）

编译链（arm-none-eabi-gcc）：Downloads | GNU Arm Embedded Toolchain Downloads – Arm Developer

下载对应平台工具链并添加到环境变量，使用arm-none-eabi-gcc -v查看是否准备就绪

OpenOCD：Download OpenOCD for Windows (gnutoolchains.com)

生成工程

使用STM32CubeMX生成工程，生成方法略

重点重点重点：生成代码时Toolchain/IDE选择Makefile

编译

在生成工程的根目录会看到Makefile文件，在根目录打开终端并输入如下命令：

make -j12

打印空间信息即编译成功，否则日志中会报错

arm-none-eabi-size build/STM32H743.elftext    data     bss     dec     hex filename22908      24    2464   25396    6334 build/STM32H743.elf

下载

参考命令如下：

openocd.exe -f "interface/cmsis-dap.cfg" -f "target/stm32h7x.cfg" -c "program STM32H743-2740.hex" -c reset -c shutdown

配置文件在OpenOCD\share\openocd\scripts下可找到，第一个是调试器的配置文件，第二个是芯片的配置文件，可以合二为一

第三个是上一节编译出的hex文件

-c reset是下载成功后复位芯片

-c shutdown是执行完成后退出OpenOCD

成功日志如下：

PS D:\OpenOCD-20231002-0.12.0\bin> .\openocd.exe -f "cmsis-dap.cfg" -f "stm32h7x.cfg" -c "program STM32H743-2740.hex" -creset -c shutdown
