    摘要:

    针对国产微控制器终端设备程序升级需要拆卸设备问题,提出了基于GD32网络在线烧写固件的方案,通过手持控制器实现对终端设备的应用程序软件升级,达到无须仿真器更新固件程序目的。该方案详细论述了在线烧写系统的组成,在应用编程技术的工作原理,以及上位机程序、手持控制器和终端设备模块各功能设计与实现,并给出了各个模块的使用步骤和方法。终端设备采用多分区操作,保证系统在升级过程中即使发生异常,也不会导致产品变砖,充分提高了系统的可维护性与容错性,手持控制器在外场升级携带方便,维护简单、方便、快捷,实验测试表明,在线更新后的固件程序能够正确运行,从而解决外场拆卸产品和挂载仿真器更新程序的困难。

    Abstract:

    The problem that the program upgrade of domestic microcontroller terminal equipment needs to be disassembled, and a solution based on GD32 network online updating firmware is proposed, which allows the application software of terminal devices to be upgraded using a handheld controller, so as to achieve the purpose of updating the firmware program without emulator.The scheme discusses in detail the composition of the online update system,the principles of application programming techniques, and the design and implementation of the functions of the upper computer program, handheld controller and terminal equipment module, and gives the usage steps and methods of each module.The terminal equipment software using a multi-partition operation to ensure that the system remains functional even in the event of an exception during the upgrade process, preventing the module from becoming unusable.This greatly enhances the maintainability and fault tolerance of the online update system. The handheld controller is easy to upgrade and carry in the field, and maintenance is simple, convenient, and fast. Through experimental testing, it is discovered that the online firmware program for updating is successful, thereby resolving the difficulty of disassembling products in the field and updating the program with the emulator.
