VSCode + JTAG调试合宙ESP32C3

环境

Windows10

VSCode + ESP-IDF

合宙ESP32C3（无串口芯片版本）

理论

想要直接使用内置JTAG，USB要求连接GPIO18和GPIO19

合宙ESP32C3有串口芯片版本USB经过CH343连接的串口，无法使用内置JTAG

合宙ESP32C3无串口芯片版本满足要求

步骤

连接PC后有一个虚拟串口和一个USB JTAG接口

按住BOOT，然后按下RST，松开BOOT，芯片进入下载模式，下载固件

启动OpenOCD和GDB前先按下RST重启芯片，运行在正常模式，而不是下载模式

使用乐鑫OpenOCD，搭配board/esp32c3-builtin.cfg

启动OpenOCD，监听3333，成功
