ESP32 flash tool hangs

[glenn0001]

Hi everyone,

I’m trying to flash an ESP32 board via USB Type-C using the nEFBox.bin file, but I’m encountering an issue. When I start the flashing process, the command line only shows:

After that, nothing else happens—the flashing tool doesn't proceed or indicate that it's loading or writing to the device.

Has anyone encountered this issue before? Any suggestions on what might be going wrong or how to fix it?

Thanks in advance!
