Configure Other JTAG Interface
|
|
==============================
|
|
:link_to_translation:`zh_CN:[中文]`
|
|
|
|
Refer to section :ref:`jtag-debugging-selecting-jtag-adapter` for guidance what JTAG interface to select, so it is able to operate with OpenOCD and {IDF_TARGET_NAME}. Then follow three configuration steps below to get it working.
|
|
|
|
|
|
Configure Hardware
|
|
^^^^^^^^^^^^^^^^^^
|
|
|
|
1. Identify all pins / signals on JTAG interface and {IDF_TARGET_NAME} board, that should be connected to establish communication.
|
|
|
|
.. only:: esp32
|
|
|
|
+---+-----------------------+-------------+
|
|
| | ESP32 Pin | JTAG Signal |
|
|
+===+=======================+=============+
|
|
| 1 | CHIP_PU | TRST_N |
|
|
+---+-----------------------+-------------+
|
|
| 2 | MTDO / GPIO15 | TDO |
|
|
+---+-----------------------+-------------+
|
|
| 3 | MTDI / GPIO12 | TDI |
|
|
+---+-----------------------+-------------+
|
|
| 4 | MTCK / GPIO13 | TCK |
|
|
+---+-----------------------+-------------+
|
|
| 5 | MTMS / GPIO14 | TMS |
|
|
+---+-----------------------+-------------+
|
|
| 6 | GND | GND |
|
|
+---+-----------------------+-------------+
|
|
|
|
.. only:: esp32s2
|
|
|
|
+---+-----------------------+-------------+
|
|
| | ESP32-S2 Pin | JTAG Signal |
|
|
+===+=======================+=============+
|
|
| 1 | CHIP_PU | TRST_N |
|
|
+---+-----------------------+-------------+
|
|
| 2 | MTDO / GPIO40 | TDO |
|
|
+---+-----------------------+-------------+
|
|
| 3 | MTDI / GPIO41 | TDI |
|
|
+---+-----------------------+-------------+
|
|
| 4 | MTCK / GPIO39 | TCK |
|
|
+---+-----------------------+-------------+
|
|
| 5 | MTMS / GPIO42 | TMS |
|
|
+---+-----------------------+-------------+
|
|
| 6 | GND | GND |
|
|
+---+-----------------------+-------------+
|
|
|
|
2. Verify if {IDF_TARGET_NAME} pins used for JTAG communication are not connected to some other h/w that may disturb JTAG operation.
|
|
|
|
3. Connect identified pin / signals of {IDF_TARGET_NAME} and JTAG interface.
|
|
|
|
|
|
Configure Drivers
|
|
^^^^^^^^^^^^^^^^^
|
|
You may need to install driver s/w to make JTAG work with computer. Refer to documentation of JTAG adapter, that should provide related details.
|
|
|
|
|
|
Connect
|
|
^^^^^^^
|
|
|
|
Connect JTAG interface to the computer. Power on {IDF_TARGET_NAME} and JTAG interface boards. Check if JTAG interface is visible by computer.
|
|
|
|
|
|
To carry on with debugging environment setup, proceed to section :ref:`jtag-debugging-run-openocd`.
