Configure {IDF_TARGET_NAME} built-in JTAG Interface
|
|
===================================================
|
|
|
|
{IDF_TARGET_NAME} has a built-in JTAG circuitry and can be debugged without any additional chip. Only an USB cable
|
|
connected to the D+/D- pins is necessary. The necessary connections are shown in the following section.

Please verify that the {IDF_TARGET_NAME} pins used for USB communication are not connected to some other HW that may disturb the JTAG operation.
|
|
|
|
Configure USB Drivers
|
|
^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
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
