esp32-s3 的gpio无法设置JTAG接口

[liucheng]

根据文档（https://docs.espressif.com/projects/esp ... -jtag.html）描述：“烧录 JTAG_SEL_ENABLE eFuse 后，JTAG 接口的选择将由 strapping 管脚 GPIO3 来决定。ESP32-S3 复位时，如果该 strapping 管脚为低电平，JTAG 接口将使用 GPIO39-GPIO42，如果为高电平，USB_SERIAL_JTAG 将被用作 JTAG 接口。”

我需要执行：espefuse.py -p /dev/ttyUSB0 burn_efuse JTAG_SEL_ENAB
使能esp32-s3的管脚为JTAG接口失败

Code: Select all

#espefuse.py -p /dev/ttyUSB0  burn_efuse JTAG_SEL_ENABLE

请问原因是什么如何解决？

我已经验证过，编译环境是ok的，下载，命令，打印log都命令都可以正常执行
idf.py set-target esp32s3 （ok）
idf.py build （ok）
idf.py -p /dev/ttyUSB0 -b 460800 flash （ok）
idf.py -p /dev/ttyUSB0 monitor （ok）

文档有问题，对于 S3，应该是 STRAP_JTAG_SEL。
JTAG_SEL_ENABLE 是针对 C3 的。

[liucheng]

1 输入命令：STRAP_JTAG_SEL

Code: Select all

#espefuse.py -p /dev/ttyUSB0  burn_efuse STRAP_JTAG_SEL

=== Run "burn_efuse" command ===

Aborting.

2 将GPIO3 接地，重启开发板
3 启动openOCD调试：

我认为步骤1,2，应该已经调试到JTAG模式了，但是步骤3中还是报错“Error: CMSIS-DAP command CMD_DAP_SWJ_CLOCK failed.”
请问有解决思路吗？我感觉还是管脚设置不对呀。。。

[ESP_Gargamel]

1、esp openocd 应该还没有支持 CMSIS-DAP
2、为什么不直接用 builtin 的 jtag？
3、你要用 jtag 的话，要么整个 https://item.taobao.com/item.htm?spm=a1 ... 062944&mt=

麻烦解释一下，也利于其他遇到类似问题的开发者。另外，使用的是哪种 JTAG？
