.. zephyr:board:: arduino_uno_q

Overview

The Arduino UNO Q is a development board featuring a Qualcomm QRB2210 processor (Quad core ARM Cortex-A53) and an STM32U585 microcontroller. The board is designed around the Arduino form factor and is compatible with traditional Arduino shields and accessories. This port targets the STM32U585 microcontroller on the board.

Hardware

Qualcomm QRB2210 Processor (Quad core ARM Cortex-A53)
STM32U585 Microcontroller (ARM Cortex-M33 at 160 MHz)
2 Mbyte of Flash memory and 786 Kbytes of RAM
2 RGB user LEDs
One 13x8 LED Matrix
Internal UART and SPI buses connected to the QRB2210
Built-in CMSIS-DAP debug adapter (through QRB2210)

Debug adapter

The QRB2210 microprocessor can act as an SWD debug adapter for the STM32U585. This is supported by the openocd binary available in the board, and its functionality can be made available to the computer via adb port forwarding commands.

This interface is not yet integrated with the west flash command, but debugging is supported.

Debugging

Debugging can be done with the usual west debug command after starting the debug server on the board. The following commands, run from an USB-connected computer, allow to debug the :zephyr:code-sample:blinky application on the Uno Q board:

.. code-block:: console

adb forward tcp:3333 tcp:3333 && adb shell arduino-debug

in a different shell

west build -b arduino_uno_q samples/basic/blinky west debug -r openocd

Restoring the Arduino sketch loader

The Arduino UNO Q comes with a pre-installed application that acts as a loader for user sketches, and is shipped as part of the Arduino Zephyr cores. If you overwrite this application, you can restore it later by issuing the following command from an USB-connected computer:

.. code-block:: console

adb shell arduino-cli burn-bootloader -b arduino:zephyr:unoq -P jlink

The same arduino-cli command can also be directly used on the board, when in standalone mode:

.. code-block:: console

arduino-cli burn-bootloader -b arduino:zephyr:unoq -P jlink
