openocd 使用的命令及参数提供下，比如：openocd -f board/esp32s2-ftdi.cfg，你用的哪个 cfg，如果是自己写的，也提供下。
从你的 log 看有 stub 相关的，你是要用 jtag 烧录固件？

你好，.cfg文件如下，修改了一点,只是把速率改成了9600，没啥影响，准备调试设备，并没有下载，另外环境在win10下面的eclipse

[ESP_Gargamel]

你先直接在终端里试一下基本的连接：
一个终端：openocd.exe -f interface/jlink.cfg -f target/esp32s2.cfg
另一个终端：xtensa-esp32s2-elf-gdb.exe，然后出现 (gdb) 后输入 target remote :3333
看下结果。

另外，建议使用带 FT2232 的 JTAG，如 https://docs.espressif.com/projects/esp ... guide.html

今天这个突然能调试了，但是还是有错误，使用的是hello_wold例程调试，加了两个断点
