Abstract
In the paper,a software upgrade system is designed for communication power controllers.The system is developed based on the GD32F405RG chip,and the RS485 communication bus is used as the information transmission mode to receive the upgrade program during the APP stage.Then the correctness of the information transmission is verified by verification algorithms such as CRC,and then the upgrade program is stored in the off-chip memory chip W25Q128JVSQ and the communication power controller is restarted.During the BootLoader stage,the upgrade program is transferred to the internal FLASH of the GD32F405RG,and the update program pro-ceeds to run after the verification is passed.The overall design and specific implementation methods of the system are described in detail.The test results show that the system successfully completes the software upgrade of the communication power controller within 15 mi-nutes,and the communication power controller operates normally after the upgrade.This software upgrade method reduces the economic investment in upgrading the maintenance process of the communication power supply,and improves their sustainability and stability.关键词
