Is it possible to run the tool using the integrate USB2CDC converter of the chip, without having to connect an external port?
I am testing with ESP32-C3-DevKitM-1 (rewired to route USB signals to the ESP, without using the on-board converter) and I can download the firmware, but get an access denied when I try to run the commands, like if the FW is disabling the USB port.
Do I need to connect to the UART pins? Should I use U0TXD and U0RXD? The documentation of the tool isn't very clear about this.
Is there a way to use just USB? I will have no dedicated UART on my custom device, so running the tool would be complicated.
As an alternative, it's possible to customize this tool? Is it open source?

As an alternative, is there a low-level documented APIs that allow me to perform the same operations done by that tool?
Continous TX etc.

Hi vm__dm,
Currently the release binaries of the RF test tool do not support USB_SERIAL_JTAG. You may, however, request a customized version of the tool with USB support if you contact Espressif technical support directly.
(The tool is not open source, and isn't available in the form of a library, unfortunately. We do plan to make at least the pre-compiled library with header files available as part of IDF, to make customizations possible. However there is no concrete timeline for that will happen.)

Thank you for the clarification, I contacted tech support.

I have the same request to use USB_SERIAL_JTAG for RF test (ESP32C3).ESP_igrr wrote: ↑Wed Dec 14, 2022 7:57 pmHi vm__dm,

Just curious do you have this support already now?
If yes, maybe espressif can add "RF test tool using USB_SERIAL_JTAG" in Tools download page.

Just following up, https://github.com/espressif/esp-idf/tr ... /cert_test can now be used to integrate certification related features into a custom application, including the one using USB_SERIAL_JTAG.
