Supported Features

.. zephyr:board-supported-hw::

Default Zephyr Peripheral Mapping:

The RA8D1-VISION-BOARD board features a On-board CMSIS-DAP debugger/programmer. Board is configured as follows:

UART9 TX/RX : P209/P208 (CMSIS-DAP Virtual Port Com)
LED0 : P102
LED1 : P106
LED2 : PA07
USER BUTTON : P907

Programming and Debugging

.. zephyr:board-supported-runners::

Applications for the ra8d1_vision_board board can be built, flashed, and debugged in the usual way. See :ref:build_an_application and :ref:application_run for more details on building and running.

Note: Only support from SDK v0.16.6 in which GCC for Cortex Arm-M85 was available. To build for RA8D1-VISION-BOARD user need to get and install GNU Arm Embedded toolchain from https://github.com/zephyrproject-rtos/sdk-ng/releases/tag/v0.16.6

Flashing

Program can be flashed to RA8D1-VISION-BOARD via the on-board DAP-LINK debugger.

Linux users: to fix the permission issue, simply add the following udev rule for the CMSIS-DAP interface:

.. code-block:: console

$ echo 'SUBSYSTEM=="usb", ATTR{idVendor}=="0416", ATTR{idProduct}=="7687", MODE:="666"' > /etc/udev/rules.d/50-cmsis-dap.rules

To flash the program to board

Connect to DAP-LINK via USB port to host PC
Execute west command

.. code-block:: console
```
 west flash
```

Debugging

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: ra8d1_vision_board :maybe-skip-config: :goals: debug
