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 ***
