Build the Project
|
|
=================
|
|
|
|
Build the project by running:
|
|
|
|
.. code-block:: batch
|
|
|
|
idf.py build
|
|
|
|
This command compiles the application and all ESP-IDF components, then it generates the bootloader, partition table, and application binaries.
|
|
|
|
.. code-block:: none
|
|
|
|
$ idf.py build
|
|

[527/527] Generating hello_world.bin
|
|
esptool.py v2.3.1
|
|
|
|
Project build complete. To flash, run this command:
|
|
../../../components/esptool_py/esptool/esptool.py -p (PORT) -b 921600 write_flash --flash_mode dio --flash_size detect --flash_freq 40m 0x10000 build/hello_world.bin build 0x1000 build/bootloader/bootloader.bin 0x8000 build/partition_table/partition-table.bin
|
|
or run 'idf.py -p PORT flash'
|
|
|
|
If there are no errors, the build finishes by generating the firmware binary .bin files.
|
|
|
|
|
|
Flash onto the Device
|
|
=====================
|
|
|
|
To flash the binaries that you just built for the {IDF_TARGET_NAME} in the previous step, you need to run the following command:
|
|
|
|
.. code-block:: bash
|
|
|
|
idf.py -p PORT flash
|
|
|
|
Replace ``PORT`` with your {IDF_TARGET_NAME} board's USB port name. If the ``PORT`` is not defined, the :ref:`idf.py` will try to connect automatically using the available USB ports.
|
|
|
|
For more information on ``idf.py`` arguments, see :ref:`idf.py`.
|
|
|
|
.. note::
|
|
|
|
The option ``flash`` automatically builds and flashes the project, so running ``idf.py build`` is not necessary.
|
|
|
|
Encountered Issues While Flashing? See the "Additional Tips" below. You can also refer to :doc:`flashing-troubleshooting` page or :doc:`establish-serial-connection` for more detailed information.
|
|
|
|
Normal Operation
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
When flashing, you will see the output log similar to the following:
|
|
|
|
.. include:: {IDF_TARGET_PATH_NAME}_output_log.inc
|
|
:start-after: output_log
|
|
|
|
If there are no issues by the end of the flash process, the board will reboot and start up the "hello_world" application.
|
|
|
|
If you would like to use the Eclipse or VS Code IDE instead of running ``idf.py``, check out `Eclipse Plugin <https://github.com/espressif/idf-eclipse-plugin/blob/master/README.md>`_, `VSCode Extension <https://github.com/espressif/vscode-esp-idf-extension/blob/master/docs/tutorial/install.md>`_.
|
|
|
|
Monitor the Output
|
|
==================
|
|
|
|
To check if "hello_world" is indeed running, type ``idf.py -p PORT monitor`` (Do not forget to replace PORT with your serial port name).
|
|
|
|
This command launches the :doc:`IDF Monitor <../api-guides/tools/idf-monitor>` application.
|
|
|
|
.. code-block:: bash
|
|
|
|
$ idf.py -p <PORT> monitor
|
|
Running idf_monitor in directory [...]/esp/hello_world/build

To exit IDF monitor use the shortcut ``Ctrl+]``.
|
|
|
|
.. only:: esp32 or esp32c2
|
|
|
|
If IDF monitor fails shortly after the upload, or, if instead of the messages above, you see random garbage similar to what is given below, your board is likely using a 26 MHz crystal. Most development board designs use 40 MHz, so ESP-IDF uses this frequency as a default value.
|
|
|
|
.. figure:: ../../_static/get-started-garbled-output.png
|
|
:align: center
|
|
:alt: Garbled output
|
|
:figclass: align-center
|
|
|
|
If you have such a problem, do the following:
|
|
|
|
1. Exit the monitor.
|
|
2. Go back to ``menuconfig``.
|
|
3. Go to ``Component config`` --> ``Hardware Settings`` --> ``Main XTAL Config`` --> ``Main XTAL frequency``, then change :ref:`CONFIG_XTAL_FREQ_SEL` to 26 MHz.
|
|
4. After that, ``build and flash`` the application again.
|
|
|
|
In the current version of ESP-IDF, main XTAL frequencies supported by {IDF_TARGET_NAME} are as follows:
|
|
|
|
.. list::
|
|
|
|
:SOC_XTAL_SUPPORT_24M: - 24 MHz
|
|
:SOC_XTAL_SUPPORT_26M: - 26 MHz
|
|
:SOC_XTAL_SUPPORT_32M: - 32 MHz
|
|
:SOC_XTAL_SUPPORT_40M: - 40 MHz
|
|
|
|
.. note::
|
|
|
|
You can combine building, flashing and monitoring into one step by running::
|
|
|
|
idf.py -p PORT flash monitor
|
|
|
|
See also:
|
|
|
|
- :doc:`IDF Monitor <../api-guides/tools/idf-monitor>` for handy shortcuts and more details on using IDF monitor.
|
|
- :ref:`idf.py` for a full reference of ``idf.py`` commands and options.
|
|
|
|
**That is all that you need to get started with {IDF_TARGET_NAME}!**
|
|
|
|
Now you are ready to try some other :idf:`examples`, or go straight to developing your own applications.
|
|
|
|
.. important::
|
|
|
|
Some of examples do not support {IDF_TARGET_NAME} because required hardware is not included in {IDF_TARGET_NAME} so it cannot be supported.
|
|
|
|
If building an example, please check the README file for the ``Supported Targets`` table. If this is present including {IDF_TARGET_NAME} target, or the table does not exist at all, the example will work on {IDF_TARGET_NAME}.

Additional Tips
|
|
===============
|
|
|
|
Permission Denied Issue
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
With some Linux distributions, you may get the error message similar to ``Could not open port <PORT>: Permission denied: '<PORT>'`` when flashing the {IDF_TARGET_NAME}. :ref:`This can be solved by adding the current user to the specific group <linux-dialout-group>`, such as ``dialout`` or ``uucp`` group.
|
|
|
|
Python Compatibility
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
ESP-IDF supports Python 3.8 or newer. It is recommended to upgrade your operating system to a recent version satisfying this requirement. Other options include the installation of Python from `sources <https://www.python.org/downloads/>`_ or the use of a Python version management system such as `pyenv <https://github.com/pyenv/pyenv>`_.
|
|
|
|
.. only:: esp32 or esp32s2 or esp32s3
|
|
|
|
..
|
|
When adding new targets to the line above, please update this list in windows-start-project.rst and linux-macos-start-project.rst
|
|
|
|
|
|
Start with Board Support Package
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
To speed up prototyping on some development boards, you can use `Board Support Packages (BSPs) <https://github.com/espressif/esp-bsp>`_, which makes initialization of a particular board as easy as few function calls.
|
|
|
|
A BSP typically supports all of the hardware components provided on development board. Apart from the pinout definition and initialization functions, a BSP ships with drivers for the external components such as sensors, displays, audio codecs etc.
|
|
|
|
The BSPs are distributed via :doc:`IDF Component Manager </api-guides/tools/idf-component-manager>`, so they can be found in `IDF Component Registry <https://components.espressif.com>`_.
|
|
|
|
.. only:: esp32
|
|
|
|
**Here is an example of how to add ESP-WROVER-KIT BSP to your project:**
|
|
|
|
.. code-block:: bash
|
|
|
|
idf.py add-dependency esp_wrover_kit
|
|
|
|
.. only:: esp32s2
|
|
|
|
**Here is an example of how to add ESP32-S2-Kaluga-Kit BSP to your project:**
|
|
|
|
.. code-block:: bash
|
|
|
|
idf.py add-dependency esp32_s2_kaluga_kit
|
|
|
|
.. only:: esp32s3
|
|
|
|
**Here is an example of how to add ESP-BOX BSP to your project:**
|
|
|
|
.. code-block:: bash
|
|
|
|
idf.py add-dependency esp-box
|
|
|
|
More examples of BSP usage can be found in `BSP examples folder <https://github.com/espressif/esp-bsp/tree/master/examples>`_.
|
|
|
|
Flash Erase
|
|
~~~~~~~~~~~
|
|
|
|
Erasing the flash is also possible. To erase the entire flash memory you can run the following command:
|
|
|
|
.. code-block:: bash
|
|
|
|
idf.py -p PORT erase-flash
|
|
|
|
For erasing the OTA data, if present, you can run this command:
|
|
|
|
.. code-block:: bash
|
|
|
|
idf.py -p PORT erase-otadata
|
|
|
|
The flash erase command can take a while to be done. Do not disconnect your device while the flash erasing is in progress.
