使用ESP32-MINI-U模组无法builtin JTAG调试

[sxliujin]

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：

Code: Select all

$ esptool.py flash_id

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：

Code: Select all

openocd -f board/esp32c3-builtin.cfg -c "program_esp build/blink.bin 0x10000 verify exit"

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。

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

[ESP_Gargamel]

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
