摘要: 针对控制系统软件在线更新或升级维护的需要，构建了SoPC远程更新系统，研究了一种远程在线更新FPGA硬件配置文件和Nios II软件可执行文件的可重构方法。通过硬件配置代码和软件可执行代码引导顺序的分析，设计了高级BootLoader，可以从任意指定地址加载应用模式映像软件代码；EPCS存储用于远程更新的工厂模式映像和多份用于天线相位控制的应用模式映像；采用自定义的CAN应用层协议，用于传输及校验数据，保证了传输的可靠性。实验验证了方案的可行性，系统可进行多份配置程序的自由切换；即使远程更新失败，FPGA也能自动加载工厂模式映像，提高了系统安全性和可靠性。

Abstract: The beam control system is the nerve center of the high power phased array antenna, responsible for precise control and condition monitoring of all the cell phases in the antenna array. In order to solve the need of online updating or maintenance of control system, a remote updating system based on SoPC is constructed. A reconfigurable method of remote online updating for FPGA hardware configuration file and Nios II software program file is proposed. The boot sequence copying hardware configuration code and software code is analyzed, and the advanced BootLoader is carried out to specify boot address of the application mode image manually. The EPCS device stores a factory pattern image for remote updates and multiple application pattern images for antenna phase control. The CAN communication bus and custom CAN application layer protocols are used to transmit data and verify data, ensuring the reliability and efficiency of the transmission. The experiment verifies the feasibility of the scheme and the system can switch between multiple configuration programs. Even if the remote update fails, the FPGA can automatically load the factory mode image to ensure the system is safe and reliable. The system is simple, and the method is flexible.-
