| |
| Overview |
| ******** |
| |
| The RW612 is a highly integrated, low-power tri-radio wireless MCU with an |
| integrated 260 MHz ARM Cortex-M33 MCU and Wi-Fi 6 + Bluetooth Low Energy (LE) 5.3 / 802.15.4 |
| radios designed for a broad array of applications, including connected smart home devices, |
| gaming controllers, enterprise and industrial automation, smart accessories and smart energy. |
| |
| The RW612 MCU subsystem includes 1.2 MB of on-chip SRAM and a high-bandwidth Quad SPI interface |
| with an on-the-fly decryption engine for securely accessing off-chip XIP flash. |
| |
| The advanced design of the RW612 delivers tight integration, low power and highly secure |
| operation in a space- and cost-efficient wireless MCU requiring only a single 3.3 V power supply. |

| The default configuration can be found in the defconfig file: |
| |
| :zephyr_file:`boards/nxp/frdm_rw612/frdm_rw612_defconfig` |
| |
| Other hardware features are not currently supported |
| |
| Programming and Debugging |
| ************************* |
| |
| Build and flash applications as usual (see :ref:`build_an_application` and |
| :ref:`application_run` for more details). |
| |
| Configuring a Debug Probe |
| ========================= |
| |
| A debug probe is used for both flashing and debugging the board. This board is |
| configured by default to use the JLink Firmware. |
| |
| Configuring a Console |
| ===================== |
| |
| Connect a USB cable from your PC to J10, and use the serial terminal of your choice |
| (minicom, putty, etc.) with the following settings: |
| |
| - Speed: 115200 |
| - Data: 8 bits |
| - Parity: None |
| - Stop bits: 1 |
| |
| Flashing |
| ======== |
| |
| Here is an example for the :zephyr:code-sample:`hello_world` application. This example uses the |
| :ref:`jlink-debug-host-tools` as default. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: frdm_rw612 |
| :goals: flash |
| |
| Open a serial terminal, reset the board (press the RESET button), and you should |
| see the following message in the terminal: |
| |
| .. code-block:: console |
| |
| ***** Booting Zephyr OS v3.6.0 ***** |
| Hello World! frdm_rw612 |
| |
| Debugging |
| ========= |
| |
| Here is an example for the :zephyr:code-sample:`hello_world` application. This example uses the |
| :ref:`jlink-debug-host-tools` as default. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: frdm_rw612 |
| :goals: debug |
| |
| Open a serial terminal, step through the application in your debugger, and you |
| should see the following message in the terminal: |
| |
| .. code-block:: console |
| |
| ***** Booting Zephyr OS zephyr-v3.6.0 ***** |
| Hello World! frdm_rw612 |
| |
| SRAM Bus Access Partitioning |
| **************************** |
| |
| RW612 supports shared access of the SRAM from both the code bus and data bus. |
| The bus used to access the SRAM is determined using two separate memory mapped address spaces. |
| The application can configure the partitioning of the SRAM access regions by a devicetree overlay. |
| For example, below is part of an overlay to change the whole SRAM to be used for data. |
| |
| .. code-block:: devicetree |
| |
| &sram_data { |
| reg = <0x0 DT_SIZE_K(1216)>; |
| }; |
| |
| |
| Wireless Connectivity Support |
| ***************************** |
| |
| Fetch Binary Blobs |
| ================== |
| |
| To support Bluetooth or Wi-Fi, frdm_rw612 requires fetching binary blobs, which can be |
| achieved by running the following command: |
| |
| .. code-block:: console |
| |
| west blobs fetch hal_nxp |
| |
| Bluetooth |
| ========= |
| |
| BLE functionality requires to fetch binary blobs, so make sure to follow |
| the ``Fetch Binary Blobs`` section first. |
| |
| frdm_rw612 platform supports the monolithic feature. The required binary blob |
| ``<zephyr workspace>/modules/hal/nxp/zephyr/blobs/rw61x_sb_ble_a2.bin`` will be linked |
| with the application image directly, forming one single monolithic image. |
| |
| Wi-Fi |
| ===== |
| |
| Wi-Fi functionality requires to fetch binary blobs, so make sure to follow |
| the ``Fetch Binary Blobs`` section first. |
| |
| frdm_rw612 platform supports the monolithic feature. The required binary blob |
| ``<zephyr workspace>/modules/hal/nxp/zephyr/blobs/rw61x_sb_wifi_a2.bin`` will be linked |
| with the application image directly, forming one single monolithic image. |
