| Overview |
| ******** |
| |
| The STM32U5A9J-DK Discovery kit is a complete demonstration and development |
| platform for the STM32U5A9NJH6Q microcontroller, featuring an Arm® Cortex®-M33 |
| core with Arm® TrustZone®. |
| |
| Leveraging the innovative ultra-low-power oriented features, 2.5 Mbytes of |
| embedded SRAM, 4 Mbytes of embedded flash memory, and rich graphics features, |
| the STM32U5A9J-DK Discovery kit enables users to easily prototype applications |
| with state-of-the-art energy efficiency, as well as providing stunning and |
| optimized graphics rendering with the support of the 2.5D NeoChrom Accelerator, |
| Chrom-ART Accelerator, and Chrom-GRC™ MMU. |
| |
| The full range of hardware features available on the board helps users to |
| enhance their application development by an evaluation of all the peripherals |
| such as a 2.47-inch RGB 480x480 pixels TFT round LCD module with MIPI DSI® |
| interface and capacitive touch panel, USB Type-C® HS, Octo-SPI flash memory |
| device, Hexadeca-SPI PSRAM memory device, eMMC flash memory device, |
| Time-of-Flight and gesture detection sensor, temperature sensor, and two 2.54 mm |
| pitch double-row flexible expansion connectors for easy prototyping with |
| daughterboards for specific applications (USART, LPUART, two SPIs, SAI, three |
| I2C, SDMMC, ADCs, timers, and GPIOs). |
| |
| The STM32U5A9J-DK Discovery kit integrates an STLINK-V3E embedded in-circuit |
| debugger and programmer for the STM32 microcontroller with a USB Virtual COM |
| port bridge and comes with the STM32CubeU5 MCU Package, which provides an STM32 |
| comprehensive software HAL library as well as various software examples. |

| System Clock |
| ============ |
| |
| The STM32U5A9J-DK Discovery kit relies on an HSE oscillator (16 MHz crystal) |
| and an LSE oscillator (32.768 kHz crystal) as clock references. |
| Using the HSE (instead of HSI) is mandatory to manage the DSI interface for |
| the LCD module and the USB high‑speed interface. |
| |
| Serial Port |
| =========== |
| |
| The STM32U5A9J Discovery kit has up to 4 USARTs, 2 UARTs, and 1 LPUART. |
| The Zephyr console output is assigned to USART1 which connected to the onboard |
| ST-LINK/V3.0. Virtual COM port interface. Default communication settings are |
| 115200 8N1. |
| |
| |
| Programming and Debugging |
| ************************* |
| |
| STM32U5A9J Discovery kit includes an ST-LINK/V3 embedded debug tool interface. |
| This probe allows to flash and debug the board using various tools. |
| |
| Flashing |
| ======== |
| |
| The board is configured to be flashed using west `STM32CubeProgrammer`_ runner, |
| so its :ref:`installation <stm32cubeprog-flash-host-tools>` is required. |
| |
| Alternatively, OpenOCD can also be used to flash the board using |
| the ``--runner`` (or ``-r``) option: |
| |
| .. code-block:: console |
| |
| $ west flash --runner openocd |
| |
| Flashing an application to STM32U5A9J_DK |
| ---------------------------------------- |
| |
| Connect the STM32U5A9J Discovery board to your host computer using the USB |
| port, then run a serial host program to connect with your Discovery |
| board. For example: |
| |
| .. code-block:: console |
| |
| $ minicom -D /dev/ttyACM0 -b 115200 |
| |
| Then, build and flash 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: stm32u5a9j_dk |
| :goals: build flash |
| |
| You should see the following message on the console: |
| |
| .. code-block:: console |
| |
| Hello World! stm32u5a9j_dk |
| |
| Debugging |
| ========= |
| |
| Default debugger for this board is openocd. It could be used in the usual way |
| with "west debug" command. |
| Here is an example for the :zephyr:code-sample:`blinky` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/basic/blinky |
| :board: stm32u5a9j_dk |
| :goals: debug |
