memory and 1MB SRAM.
The board features:
- RGB LED
- Reset and Boot buttons
- USB-C device
- USB Host
- 16MB external QSPI flash
- 8MB external SDRAM
- Murata Type 1DX Bluetooth + WiFi module (CYW4343W based)
- Audio jack
- ATECC608A secure element

Fetch Binary Blobs
******************
The board Bluetooth/WiFi module requires fetching some binary blob files, to do
that run the command:
.. code-block:: console
west blobs fetch hal_infineon
.. note:: Only Bluetooth functionality is currently supported.
Resources sharing
=================
The dual core nature of STM32H747 SoC requires sharing HW resources between the
two cores. This is done in 3 ways:
- **Compilation**: Clock configuration is only accessible to M7 core. M4 core only
has access to bus clock activation and deactivation.
- **Static pre-compilation assignment**: Peripherals such as a UART are assigned in
devicetree before compilation. The user must ensure peripherals are not assigned
to both cores at the same time.
- **Run time protection**: Interrupt-controller and GPIO configurations could be
accessed by both cores at run time. Accesses are protected by a hardware semaphore
to avoid potential concurrent access issues.
Programming and Debugging
*************************
Applications for the ``arduino_giga_r1`` board should be built per core target,
using either ``arduino_giga_r1_m7`` or ``arduino_giga_r1_m4`` as the target.
See :ref:`build_an_application` for more information about application builds.
Flashing
========
This board can be flashed either using dfu-util, or with an external debugging
probe, such as a J-Link or Black Magic Probe, connected to the on board MIPI-10
SWD port marked as "JTAG".
.. note::
The board ships with a custom Arduino bootloader programmed in the first
flash page that can be triggered by double clicking the ``RST`` button. This
bootloader is USB-DFU compatible and supports programming both the internal
and external flash and is the one used by ``west flash`` by default. The
internal STM32 ROM bootloader can also be used by pressing ``RST`` while
holding the ``BOOT0`` button, this also supports USB-DFU but can only
program the internal flash and can overwrite the Arduino bootloader. More
details can be found in the "Boot0" section of the `Arduino GIGA Cheat
Sheet`_.
First, connect the Arduino GIGA R1 board to your host computer using the USB
port to prepare it for flashing. Double click the ``RST`` button to put the
board into the Arduino Bootloader mode. Then build and flash your application.
Here is an example for the :ref:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: arduino_giga_r1_m7
:goals: build flash
Run a serial host program to connect with your board:
.. code-block:: console
$ minicom -D /dev/ttyACM0
You should see the following message on the console:
.. code-block:: console
Hello World! arduino_giga_r1_m7
Similarly, you can build and flash samples on the M4 target.
Here is an example for the :zephyr:code-sample:`blinky` application on M4 core.
.. zephyr-app-commands::
:zephyr-app: samples/basic/blinky
:board: arduino_giga_r1_m4
:goals: build flash
Debugging
=========
Debugging is supported by using ``west debug`` with an external probe such as a
J-Link or Black Magic Probe, connected to the on board MIPI-10 SWD port marked
as "JTAG". For example::
west debug -r jlink
