JTAG communication should work out-of-box on Linux and macOS. Windows users might get `LIBUSB_ERROR_NOT_FOUND` errors.
This is a known issue and will be addressed soon.
JTAG communication should work on all supported platforms. Windows users might get `LIBUSB_ERROR_NOT_FOUND` errors.
Please use version 2.8 (or newer) of the :ref:`get-started-windows-tools-installer` and select the driver
"Espressif - WinUSB support for JTAG (ESP32-C3)" in order to resolve this issue. If you don't want to re-run the
installer then the same can be achieved with `idf-env <https://github.com/espressif/idf-env>`_ by running the
following command from PowerShell::
Invoke-WebRequest 'https://dl.espressif.com/dl/idf-env/idf-env.exe' -OutFile .\idf-env.exe; .\idf-env.exe driver install --espressif

Debugging using JTAG and application loading / monitoring is integrated under the `Eclipse <https://www.eclipse.org/>`_ environment, to provide quick and easy transition from writing, compiling and loading the code to debugging, back to writing the code, and so on. All the software is available for Windows, Linux and MacOS platforms.

If the |devkit-name-with-link| is used, then connection from PC to {IDF_TARGET_NAME} is done effectively with a single USB cable. This is made possible by the FT2232H chip, which provides two USB channels, one for JTAG and the one for UART connection.

The connection from PC to {IDF_TARGET_NAME} is done effectively with a single USB cable. This is made possible by the {IDF_TARGET_NAME} chip itself, which provides two USB channels, one for JTAG and one for the USB terminal connection. The USB cable should be connected the D+/D- USB pins of {IDF_TARGET_NAME} and not to the serial RxD/TxD throught an USB-to-UART chip. The proper connection is explained later in subsection :ref:`jtag-debugging-configuring-target`.

.. note::
Debugging through the USB interface implemented in {IDF_TARGET_NAME} requires to have a chip with revision 3 or newer. Please use other debugging options (e.g. with ESP-Prog) for chip revision 1 and 2. The easiest way to determine the chip revision is to look for the `Chip is ESP32-C3 (revision 3)` message near the end of a successful chip flashing done by `idf.py flash`.

The quickest and most convenient way to start with JTAG debugging is by using |devkit-name-with-link|. Each version of this development board has JTAG interface already built in. No need for an external JTAG adapter and extra wiring / cable to connect JTAG to {IDF_TARGET_NAME}. |devkit-name| is using FT2232H JTAG interface operating at 20 MHz clock speed, which is difficult to achieve with an external adapter.
