|
|
|
Not all hardware features are supported yet. See `Raspberry Pi hardware`_ for the complete list of hardware features. |
|
|
|
The default configuration can be found in |
|
:zephyr_file:`boards/raspberrypi/rpi_5/rpi_5_defconfig`. |
|
|
|
Programming and Debugging |
|
************************* |
|
|
|
Blinky |
|
====== |
|
|
|
In brief, |
|
1. Format your Micro SD card with MBR and FAT32. |
|
2. Save three files below in the root directory. |
|
* config.txt |
|
* zephyr.bin |
|
* `bcm2712-rpi-5.dtb`_ |
|
3. Insert the Micro SD card and power on the Raspberry Pi 5. |
|
|
|
then, You will see the Raspberry Pi 5 running the :file:`zephyr.bin`. |
|
|
|
config.txt |
|
---------- |
|
|
|
.. code-block:: text |
|
|
|
kernel=zephyr.bin |
|
arm_64bit=1 |
|
|
|
|
|
zephyr.bin |
|
---------- |
|
|
|
Build an app, for example :zephyr:code-sample:`blinky` |
|
|
|
.. zephyr-app-commands:: |
|
:zephyr-app: samples/basic/blinky |
|
:board: rpi_5 |
|
:goals: build |
|
|
|
Copy :file:`zephyr.bin` from :file:`build/zephyr` directory to the root directory of the Micro SD |
|
card. |
|
|
|
Insert the Micro SD card and power on the Raspberry Pi 5. And then, the STAT LED will start to blink. |
|
|
|
|
|
Serial Communication |
|
==================== |
|
|
|
wiring |
|
------ |
|
|
|
You will need the following items: |
|
* `Raspberry Pi Debug Probe`_ |
|
* JST cable: 3-pin JST connector to 3-pin JST connector cable |
|
* USB cable: USB A male - Micro USB B male |
|
|
|
Use the JST cable to connect the Raspberry Pi Debug Probe UART port to the Raspberry Pi 5 UART port between the HDMI ports. |
|
|
|
Then connect the Raspberry Pi Debug Probe to your computer with a USB cable. |
|
|
|
|
|
config.txt |
|
---------- |
|
|
|
.. code-block:: text |
|
|
|
kernel=zephyr.bin |
|
arm_64bit=1 |
|
enable_uart=1 |
|
uart_2ndstage=1 |
|
|
|
|
|
zephyr.bin |
|
---------- |
|
|
|
Build an app, for example :ref:`hello_world`: |
|
|
|
.. zephyr-app-commands:: |
|
:zephyr-app: samples/hello_world |
|
:board: rpi_5 |
|
:goals: build |
|
|
|
Copy :file:`zephyr.bin` from :file:`build/zephyr` directory to the root directory of the Micro SD card. |
|
|
|
Insert the Micro SD card into your Raspberry Pi 5. |
|
|
|
|
|
serial terminal emulator |
|
------------------------ |
|
|
|
When you power on the Raspberry Pi 5, you will see the following output in the serial console: |
|
|
|
.. code-block:: text |
|
|
|
