【经验】解析SekormStudio配置Jlink调试程序指南

本文介绍如何使用SekormStudio配置Jlink工具调试程序。首先在世强硬创平台下载SekormStudio和STM32_workspace最新版本，https://www.sekorm.com/doc/3748183.html。本文以ST的MCU STM32工程作为案例，其他诸多国产厂牌例如：中科芯、国民技术、雅特力、芯海等的MCU芯片做法类似，可支持ARM、RISC-V等内核，可支持Windows和Linux等平台，如果有问题可以和世强FAE联系。

首先通过SekormStudio集成开发环境导入STM32_workspace工作空间，选择STM32F0xx工程进行编译（平台提供的工程已经做好配置可以直接测试体验，不同厂商不同芯片型号需要修改链接文件*.ld，汇编起始文件startup_*.S，寄存器描述文件*.svd，世强FAE提供技术支持），然后再选择调试配置，如下图所示：

打开调试配置界面选择GDB SEGGER J-Link Debugging新建调试配置，然后选择对应项目，以及调试程序STM32F0xx.elf文件。如下图所示：

打开Debugger选项栏，配置Segger Jlink gdb服务器，可以使用绝对路径和调试器局部变量的相对路径。默认使用SekormStudio包含Segger工具软件路径：${jlink_path}\${jlink_gdbserver}。必须明确指定芯片型号，且此型号是Segger Jlink已经包含的型号，如果没有型号需要手动在Segger目录下添加具体型号，必须一一对应。仿真器接口通信频率起初可设置固定值1000，速度越低稳定性强。连接成功后可以根据硬件环境和需要修改仿真器接口通信速度。注意接口方式，默认使用SWD。如下图所示：

打开SVD Path选项栏，寄存器描述文件STM32F030.svd。可以使用绝对路径直接指定，也可以使用调试局部变量的相对路径，使用‘/’目录间隔符可支持Linux环境。如下所示：

${project_loc}/../../../STM32F0xx_DFP/2.1.0/CMSIS/SVD/STM32F030.svd

点击调试按键提示切换进入调试界面，左上角红色框按键可实现单步调试，右上角红色框内容包含变量、断电、表达式、反汇编、Peripherals（外设寄存器），可选择观察。

寄存器栏可观察core内核寄存器数据，内存栏可根据需要选择外设寄存器进行数据观察和修改。以及控制台输出信息如下所示：
