该项目介绍，如何在飞腾信息科技有限公司SOC硬件平台上运行 OpenHarmony 标准系统。其中腾锐D系列芯片没有图形模块，需要搭配GPU使用，目前仓库中支持的显卡包含飞腾X100套片、AMD显卡、JM9100显卡、cpu模拟mesa3D。 最新版本支持OH 5.1.0 release
Linux in itself is not real time capable. With the additional PREEMPT_RT patch it gains real-time capabilities. The key point of the PREEMPT_RT patch is to minimize the amount of kernel code that is non-preemptible, while also minimizing the amount of code that must be changed in order to provide this added preemptibility. In particular, critical sections, interrupt handlers, and interrupt-disable code sequences are normally preemptible. The PREEMPT_RT patch leverages the SMP capabilities of the Linux kernel to add this extra preemptibility without requiring a complete kernel rewrite.

本项目是vxWorks6.9.4版本的D2000参考板BSP源码。 可依此创建操作系统映像工程，编译生成vxWorks.bin，32位SMP模式。详细启动步骤请参考target.ref文件。 注意：只用此BSP，不修改target/src/arch/arm 库源码的时候，只能启动两个核。需要修改20bsp.cdf文件中的VX_SMP_NUM_CPUS值，DEFAULT值8改为2。
