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
|
|
*************************
|
|
|
|
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
|
|
|
|
