ESP32S3 Ubuntu vscode如何使用USB-JTAG调试

一、官方文档

openocd-esp32的问题汇总： Troubleshooting
esp32的官方文档：调试项目

二、配置

1. 添加 udev 规则

bash 复制代码

sudo tee /etc/udev/rules.d/99-espressif-jtag.rules > /dev/null <<EOF
SUBSYSTEM=="usb", ATTR{idVendor}=="303a", ATTR{idProduct}=="1001", MODE="0666", GROUP="plugdev"
EOF

然后：

bash 复制代码

sudo udevadm control --reload-rules
sudo udevadm trigger

拔掉 ESP32-S3，重新插入 USB。

2. 验证 USB 设备是否识别

bash 复制代码

lsusb | grep 303a

应看到类似行：

复制代码

Bus 001 Device 042: ID 303a:1001 Espressif USB JTAG/Serial Debug Unit

3. 确认当前用户在 plugdev 组

bash 复制代码

groups $USER

若无 plugdev：

bash 复制代码

sudo usermod -a -G plugdev $USER
newgrp plugdev

4. vscode开启openocd

重启 OpenOCD 或 ESP-IDF 监视调试：

bash 复制代码

idf.py openocd
# 或：
openocd -f board/esp32s3-builtin.cfg

左下角选择JTAG，ctrl+shift+p选择openocd manager->start openocd

正常情况的openocd输出：

5. vscode的launch.json

查询 GDB 路径find ~/.espressif -name xtensa-esp32s3-elf-gdb，然后配置miDebuggerPath
配置

json 复制代码

}

三、实际测试

点击调试按钮，正常显示断点

正常的log输出的如下
