我该怎么才能查看到 寄存器的值

[yogi_yi]

我在 VSCODE 中
Type "apropos word" to search for commands related to "word".
(gdb) x/8x 0x3F409000
0x3f409000: Cannot access memory at address 0x3f409000

猜你说的是 S2，但你最好告知一下是哪个芯片的。
在 openocd 的窗口有无相关 error log？试了下 S2，没有遇到问题：

Code: Select all

(gdb) x/8x 0x3F409000
0x3f409000:	0x000027ff	0x00000b00	0x00000a00	0x00000a00
0x3f409010:	0x00000800	0x00000800	0x00000800	0x00000800

我再VSCODE 中执行，没有出现，是需要做什么相关设置吗

[ESP_Gargamel]

你这没有出现是什么意思？你需要先保证 openocd 运行正常，在此基础上通过 gdb 就可以去读相关寄存器或地址的值。

ubuntu 中 VSCODE 环境

openocd sever 已经运行
在 terminal 下
（gdb) x/8x 0x3F409000
0x3f409000: Cannot access memory at address 0x3f409000

把你 openocd 的命令，以及 log 贴一下。

我在 VSCODE 直接点击 Openocd 可以执行
在终端中 执行您给的
ubuntu:~/esp/esp_magnetic_designing$ idf.py openocd

另开终端 执行 idf.py gdbtui

esp_magnetic_designing 是你的工程目录吗？需要在工程目录下编译烧录，然后再调试。
