| Arduino UNO R4 Minima |
| ##################### |
| |
| Overview |
| ******** |
| |
| The Arduino UNO R4 Minima is a development board featuring the Renesas RA4M1 SoC |
| in the Arduino form factor and is compatible with traditional Arduino. |
| |
| Programming and debugging |
| ************************* |
| |
| Building & Flashing |
| =================== |
| |
| You can build and flash an application in the usual way (See |
| :ref:`build_an_application` and |
| :ref:`application_run` for more details). |
| |
| Here is an example for building and flashing the :zephyr:code-sample:`blinky` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/basic/blinky |
| :board: arduino_uno_r4_minima |
| :goals: build flash |
| |
| Debugging |
| ========= |
| |
| Debugging also can be done in the usual way. |
| The following command is debugging the :zephyr:code-sample:`blinky` application. |
| Also, see the instructions specific to the debug server that you use. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/basic/blinky |
| :board: arduino_uno_r4_minima |
| :maybe-skip-config: |
| :goals: debug |
| |
| |
| Using pyOCD |
| ----------- |
| |
| Various debug adapters, including cmsis-dap probes, can debug the Arduino UNO R4 with pyOCD. |
| The default configuration uses the pyOCD for debugging. |
| You must install CMSIS-Pack when flashing or debugging Arduino UNO R4 Minima with pyOCD. |
| If not installed yet, execute the following command to install CMSIS-Pack for Arduino UNO R4. |
| |
| .. code-block:: console |
| |
| pyocd pack install r7fa4m1ab |
| |
| |
| Restoring Arduino Bootloader |
| ============================ |
| |
| If you corrupt the Arduino bootloader, you can restore it with the following command. |
| |
| .. code-block:: console |
| |
| wget https://raw.githubusercontent.com/arduino/ArduinoCore-renesas/main/bootloaders/UNO_R4/dfu_minima.hex |
| pyocd flash -e sector -a 0x0 -t r7fa4m1ab dfu_minima.hex |
