| RF module, and numerous peripherals. |
| |
| ESP32-S3-Matrix includes the following features: |
| |
| - Dual core 32-bit Xtensa Microprocessor (Tensilica LX7), running up to 240MHz |
| - Additional vector instructions support for AI acceleration |
| - 512KB of SRAM |
| - 2MB of PSRAM |

| |
| Digital interfaces: |
| |
| - 15 programmable GPIOs |
| |
| Low Power: |
| |
| - Power Management Unit with five power modes |

| ******************************** |
| |
| ESP32-S3 allows 2 different applications to be executed in ESP32-S3 SoC. Due to its dual-core |
| architecture, each core can be enabled to execute customized tasks in stand-alone mode |
| and/or exchanging data over OpenAMP framework. See :zephyr:code-sample-category:`ipc` folder as code reference. |
| |
| For more information, check the datasheet at `ESP32-S3 Datasheet`_ or the technical reference |
| manual at `ESP32-S3 Technical Reference Manual`_. |
| |
| Supported Features |
| ================== |
| |
| .. zephyr:board-supported-hw:: |
| |
| Prerequisites |
| ------------- |
| |
| Espressif HAL requires WiFi and Bluetooth binary blobs in order work. Run the command |
| below to retrieve those files. |
| |
| .. code-block:: console |
| |
| west blobs fetch hal_espressif |
| |
| .. note:: |
| |
| It is recommended running the command above after :file:`west update`. |
| |
| Building & Flashing |
| ******************* |
| |
| .. zephyr:board-supported-runners:: |
| |
| Simple boot |
| =========== |
| |
| The board could be loaded using the single binary image, without 2nd stage bootloader. |
| It is the default option when building the application without additional configuration. |
| |
| .. note:: |
| |
| Simple boot does not provide any security features nor OTA updates. |
| |
| MCUboot bootloader |
| ================== |
| |
| User may choose to use MCUboot bootloader instead. In that case the bootloader |
| must be built (and flashed) at least once. |
| |
| There are two options to be used when building an application: |
| |
| 1. Sysbuild |
| 2. Manual build |
| |
| .. note:: |
| |
| User can select the MCUboot bootloader by adding the following line |
| to the board default configuration file. |
| |
| .. code:: cfg |
| |
| CONFIG_BOOTLOADER_MCUBOOT=y |
| |
| Sysbuild |
| ======== |
| |
| The sysbuild makes possible to build and flash all necessary images needed to |
| bootstrap the board with the ESP32-S3 SoC. |
| |
| To build the sample application using sysbuild use the command: |
| |
| .. zephyr-app-commands:: |
| :tool: west |
| :zephyr-app: samples/hello_world |
| :board: esp32s3_matrix/esp32s3/procpu |
| :goals: build |
| :west-args: --sysbuild |
| :compact: |
| |
| By default, the ESP32 sysbuild creates bootloader (MCUboot) and application |
| images. But it can be configured to create other kind of images. |
| |
| Build directory structure created by sysbuild is different from traditional |
| Zephyr build. Output is structured by the domain subdirectories: |
| |
| .. code-block:: |
| |
| build/ |
| ├── hello_world |
| │ └── zephyr |
| │ ├── zephyr.elf |
| │ └── zephyr.bin |
| ├── mcuboot |
| │ └── zephyr |
| │ ├── zephyr.elf |
| │ └── zephyr.bin |
| └── domains.yaml |
| |
| .. note:: |
| |
| With ``--sysbuild`` option the bootloader will be re-build and re-flash |
| every time the pristine build is used. |
| |
| For more information about the system build please read the :ref:`sysbuild` documentation. |
| |
| Manual build |
| ============ |
| |
| During the development cycle, it is intended to build & flash as quickly possible. |
| For that reason, images can be built one at a time using traditional build. |
| |
| The instructions following are relevant for both manual build and sysbuild. |
| The only difference is the structure of the build directory. |
| |
| .. note:: |
| |
| Remember that bootloader (MCUboot) needs to be flash at least once. |
| |
| Build and flash applications as usual (see :ref:`build_an_application` and |
| :ref:`application_run` for more details). |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: esp32s3_matrix/esp32s3/procpu |
| :goals: build |
| |
| The usual ``flash`` target will work with the ``esp32s3_matrix`` board |
| configuration. Here is an example for the :zephyr:code-sample:`hello_world` |
| application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: esp32s3_matrix/esp32s3/procpu |
| :goals: flash |
| |
| Open the serial monitor using the following command: |
| |
| .. code-block:: shell |
| |
| west espressif monitor |
| |
| After the board has automatically reset and booted, you should see the following |
| message in the monitor: |
| |
| .. code-block:: console |
| |
| ***** Booting Zephyr OS vx.x.x-xxx-gxxxxxxxxxxxx ***** |
| Hello World! esp32s3_matrix |
| |
| Debugging |
| ********* |
| |
| ESP32-S3 support on OpenOCD is available at `OpenOCD ESP32`_. |
| |
| ESP32-S3 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. |
| |
| Further documentation can be obtained from the SoC vendor in `JTAG debugging for ESP32-S3`_. |
| |
| Here is an example for building the :zephyr:code-sample:`hello_world` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: esp32s3_matrix/esp32s3/procpu |
| :goals: build flash |
| |
| You can debug an application in the usual way. Here is an example for the :zephyr:code-sample:`hello_world` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: esp32s3_matrix/esp32s3/procpu |
| :goals: debug |
