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. |
|
|

|
Fetch Binary Blobs |
|
|
****************** |
|
|
|
|
|
To support Bluetooth, rd_rw612_bga requires fetching binary blobs, which can be |
|
|
achieved by running the following command: |
|
|
|
|
|
.. code-block:: console |
|
|
|
|
|
west blobs fetch hal_nxp |
|
|
|
|
|
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 J7, 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 :ref:`hello_world` application. This example uses the |
|
|
:ref:`jlink-debug-host-tools` as default. |
|
|
|
|
|
.. zephyr-app-commands:: |
|
|
:zephyr-app: samples/hello_world |
|
|
:board: rd_rw612_bga |
|
|
: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 v3.4.0 ***** |
|
|
Hello World! rd_rw612_bga |
|
|
|
|
|
Debugging |
|
|
========= |
|
|
|
|
|
Here is an example for the :ref:`hello_world` application. This example uses the |
|
|
:ref:`jlink-debug-host-tools` as default. |
|

|
|

|
|
: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! rd_rw612_bga |
|
|
|
|
|
Bluetooth |
|
|
********* |
|
|
|
|
|
BLE functionality requires to fetch binary blobs, so make sure to follow |
|
|
the ``Fetch Binary Blobs`` section first. |
|
|
|
|
|
Those binary blobs can be used in two different ways, depending if :kconfig:option:`CONFIG_NXP_MONOLITHIC_BT` |
|
|
is enabled or not: |
|
|
|
|
|
- :kconfig:option:`CONFIG_NXP_MONOLITHIC_BT` is enabled (default): |
|
|
|
|
|
The required binary blob will be linked with the application image directly, forming |
|
|
one single monolithic image. |
|
|
The user has nothing else to do other than flashing the application to the board. |
|
|
|
|
|
- :kconfig:option:`CONFIG_NXP_MONOLITHIC_BT` is disabled: |
|
|
|
|
|
In this case, the BLE blob won't be linked with the application, so the user needs to manually |
|
|
flash the BLE binary blob to the board at the address ``0x18540000``. |
|
|
The binary blob will be located here: ``<zephyr workspace>/modules/hal/nxp/zephyr/blobs/rw61x/rw61x_sb_ble_a2.bin`` |
|
|
|
|
|
Board variants |
|
|
************** |
|
|
|
|
|
Ethernet |
|
|
======== |
|
|
|
|
|
To use ethernet on the RD_RW612_BGA board, you first need to make the following |
|
|
modifications to the board hardware: |
|
|
|
|
|
Add resistors: |
|
|
|
|
|
- R485 |
|
|
- R486 |
|
|
- R487 |
|
|
- R488 |
|
|
- R489 |
|
|
- R491 |
|
|
- R490 |
|
|
|
|
|
Remove resistors: |
|
|
|
|
|
- R522 |
|
|
- R521 |
|
|
- R520 |
|
|
- R524 |
|
|
- R523 |
|
|
- R508 |
|
|
- R505 |
|
|
|
|
|
Then, build for the board target ``rd_rw612_bga//ethernet``. |
