Porting and Developing the OpenHarmony System Based on Zynq

With the rapid development of particle accelerator technology, the complexity and integration requirements of software systems are increasing, leading to many challenges in the sustainability and maintenance efficiency of application software. In order to improve the overall performance of accelerator systems, simplify integration and maintenance, reduce costs, achieve the goal of fully autonomous controllable digital pedestals in the accelerator field and promote software standardization, analyzing accelerator controller requirements and OpenHarmony related technologies, designing and implementing a minimal system migration that includes porting the OpenHarmony kernel, adding subsystems, and customizing the root file system were performed. The experimental verification shows that the OpenHarmony is successfully adapted to the accelerator controller equipped with Zynq7045 chip, and can run stably and reliably.
