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
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:
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
lsusb | grep 303a
应看到类似行:
Bus 001 Device 042: ID 303a:1001 Espressif USB JTAG/Serial Debug Unit
3. 确认当前用户在 plugdev 组
groups $USER
若无 plugdev
:
sudo usermod -a -G plugdev $USER
newgrp plugdev
4. vscode开启openocd
- 重启 OpenOCD 或 ESP-IDF 监视调试:
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

}
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
