ROC-RK3568-PC (Quad-core Cortex-A55)

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:

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 Basic Synchronization sample:

# From the root of the zephyr repository
west build -b roc_rk3568_pc samples/synchronization
west build -t run

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

***  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 Basic Synchronization sample:

# From the root of the zephyr repository
west build -b roc_rk3568_pc//smp samples/synchronization
west build -t run

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

***  Booting Zephyr OS build bc695c6df5eb  ***

I/TC: Secondary CPU 1 switching to normal world boot
I/TC: Secondary CPU 2 initializing

Secondary CPU core 2 (MPID:0x200) is up
Secondary CPU core 3 (MPID:0x300) is up
