Supported Features

.. zephyr:board-supported-hw::

Devices

System Clock

This board configuration uses a system clock frequency of 24 MHz. Cortex-A55 Core runs up to 2.0 GHz.

Serial Port

This board configuration uses a single serial communication channel with the CPU's UART2.

Programming and Debugging

.. zephyr:board-supported-runners::

Use U-Boot to load the zephyr.bin to the memory and kick it:

.. code-block:: console

tftp 0x40000000 zephyr.bin; dcache flush; icache flush; dcache off; icache off; go 0x40000000

Use this configuration to run basic Zephyr applications and kernel tests, for example, with the :zephyr:code-sample:synchronization sample:

.. zephyr-app-commands:: :zephyr-app: samples/synchronization :host-os: unix :board: roc_rk3568_pc :goals: run

This will build an image with the synchronization sample app, boot it and display the following ram console output:

.. code-block:: console

***  Booting Zephyr OS build bc695c6df5eb  ***
thread_a: Hello World from cpu 0 on roc_rk3568_pc!
thread_b: Hello World from cpu 0 on roc_rk3568_pc!
thread_a: Hello World from cpu 0 on roc_rk3568_pc!
thread_b: Hello World from cpu 0 on roc_rk3568_pc!

roc_rk3568_pc//smp support, use this configuration to run Zephyr smp applications and subsys tests, for example, with the :zephyr:code-sample:synchronization sample:

.. zephyr-app-commands:: :zephyr-app: samples/synchronization :host-os: unix :board: roc_rk3568_pc//smp :goals: run

This will build an image with the shell_module sample app, boot it and display the following ram console output:

.. code-block:: console
