| Overview |
| ******** |
| |
| The ROC-RK3568-PC is a Quad-Core 64-Bit Mini Computer, which supports 4G large RAM. M.2 |
| and SATA3.0 interfaces enables expansion with large hard drives. |
| Providing dual Gigabit Ethernet ports, it supports WiFi 6 wireless transmission. |
| Control Port can be connected with RS485/RS232 devices. |
| |
| RK3568 quad-core 64-bit Cortex-A55 processor, with brand new ARM v8.2-A architecture, |
| has frequency up to 2.0GHz. Zephyr OS is ported to run on it. |

| 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 |
| |
| *** Booting Zephyr OS build bc695c6df5eb *** |
