General issue report

烧录hello_world程序时，在flash device阶段遇到问题。 端口设置确认没有问题，目标芯片选择的是esp32c6的“builtin usb jtag”，编译完成没有报错。烧录时提示打开openocd。打开openocd时出现以下错误： c:\Users\TangTao\esp\tools\openocd-esp32\v0.12.0-esp32-20230419\openocd-esp32\bin\openocd.exe

Please check the device manager to see if the USB Serial/JTAG device is detected by the system.

[woshiwstt50123]

确认被操作系统识别。操作系统里显示这个端口的名字是“USB串行设备（COM7）”

[igrr]

That looks like a USB-Serial bridge (CP2102). The name of the built-in USB of C6 is "USB Serial/JTAG Debug Unit". Please check the VID and PID of the device to confirm.

[woshiwstt50123]

不是。“Silicon Labs CP210x USB to UART Bridge”是另外一个USB插槽插入后的名字。它和“USB串行设备（COM7）”不是同一个接口。

[woshiwstt50123]

它的VID和PID有两行： USB\VID_303A&PID_1001&REV_0102&MI_00 USB\VID_303A&PID_1001&MI_00

When installing IDF, have you selected the option to install the USB driver (https://dl.espressif.com/dl/idf-driver/idf-driver-esp32-usb-jtag-2021-07-15.zip)? Please check once.

[woshiwstt50123]

有，在“.espressif\tools\idf-driver\idf-driver-esp32-usb-jtag-2021-07-15”下面。

[woshiwstt50123]

奇怪，我没有在vscode的插件里看到安装这个驱动的选项。

ID to 0x1002

VID_303A&PID_1001

Looks like VS Code is configured to use a different JTAG adapter than the one you are using. You probably need to select "ESP32-C6 chip (via builtin USB-JTAG)" instead of "ESP32-C6 chip (via ESP USB Bridge)" in VS Code.

[woshiwstt50123]

我把原来的文件全部删掉，然后重新复制一份，这样才能成功下载进去。是不是在使用“ESP32-C6 chip (via ESP USB Bridge)”或其他类似选项时会引入新的文件让“ESP32-C6 chip (via builtin USB-JTAG)”的选项失效？

[woshiwstt50123]

Error: esp_usb_jtag: could not find or open device!这个问题现在又出现了。我已经确认选择的是“ESP32-C6 chip (via builtin USB-JTAG)”，并且USB串行设备（COM7）也已经识别到
