使用同样的代码和工程配置挂载合宙9.9元的开发板JTAG是可以的，环境使用的是Espressif-IDE 2.5
现在工程PCB使用的是ESP32-C3-MINI-U模组
观察硬件差异只有合宙9.9元的开发板的FLASH是外置的
ESP32-C3-MINI-U模组是片内FLASH
在工程中已经关闭了内存保护，但模组还是挂不上JTAG，日志如下：
大概能看出来是openocd对flash的操作有什么问题

你应该是用 ESP-IDF Windows Installer 安装的 IDF 开发环境，直接用命令行，IDF CMD，或者 IDF PowerShell，先读一下 MINI 模组的 flash id： 然后： 看一下运行结果。
同时也提供一下合宙开发板的输出结果。

合宙和我的模组虽然相比您的日志报了多了ERROR，而且DEVICE的编号不一样，但是合宙的开发板确实能挂上JTAG，下面是在Espressif-IDE中terminal的信息

另外我更新了openocd 到最新的v0.11.0-esp32-20220706版本，并且降低了JTAG的时钟，但都没有效果，新的错误信息如下：

我没有 windows，也没用过 windows 下的 eclipse IDE。暂时不确认这是 eclipse 带进来的问题，还是 openocd 的问题。
请直接用 openocd 命令烧录试一下，可以使用 blink 示例，或者烧你自己工程的 bootloader.bin，注意路径和烧写起始地址： 我这边在 linux 下用这个命令烧录没有问题，你那边如果这个烧录没有问题的话，可以把 eclipse 里自动烧录的功能关掉，调试前先用 idf.py flash 或以上命令烧录。

您好，通过shell命令行，错误也是相同的。

试了下 Windows，也没遇到问题。 你再用 读取一下 efuse 看看，串口改成你自己的。另外，换 Linux 试试，换个板子试试，看看情况。

efuse内部关于JTAG的那一项 我查是说用4线TMS TCK TDO TDI 模式才需要熔断，builtin-JTAG不需要操作

efuse 没有问题。
你先用 idf.py flash 把程序烧录一次，然后再试一下。
试了把 flash 都擦掉，然后烧录： 前面会有 error，但还是可以 detect 到 flash。

您好，按您的方式操作后发现还是不能挂JTAG，但是现在报错变了
