Asymmetric Multiprocessing (AMP)
********************************
ESP32S3-DevKitC 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 :ref:`ipc_samples` folder as code reference.
For more information, check the datasheet at `ESP32-S3 Datasheet`_.

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
*******************
ESP-IDF bootloader
==================
The board is using the ESP-IDF bootloader as the default 2nd stage bootloader.
It is build as a subproject at each application build. No further attention
is expected from the user.
MCUboot bootloader
==================
User may choose to use MCUboot bootloader instead. In that case the bootloader
must be build (and flash) 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.
```
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
:app: samples/hello_world
:board: esp32s3_devkitc/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 build 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_devkitc/esp32s3/procpu
:goals: build
The usual ``flash`` target will work with the ``esp32s3_devkitc`` board
configuration. Here is an example for the :ref:`hello_world`
application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: esp32s3_devkitc/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_devkitc
Debugging
*********
ESP32-S3 support on OpenOCD is available upstream as of version 0.12.0.
Download and install OpenOCD from `OpenOCD`_.
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 :ref:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: esp32s3_devkitc/esp32s3/procpu
:goals: build flash
You can debug an application in the usual way. Here is an example for the :ref:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: esp32s3_devkitc/esp32s3/procpu
:goals: debug
