摘　　要：现有脱机下载器对中科芯CKS系列32位单片机的兼容性不足。在无计算机环境下,对32位单片机进行便捷程序下载的需求较为迫切。特别是在产线大批量生产中,需要高效连续下载程序。针对以上问题,文章提出了一种基于CKS32单片机的脱机下载器设计方案。该方案中,目标程序文件通过电脑端上位机软件经USB接口下载并存储于CKS32单片机外接的FLASH芯片中。CKS32单片机作为核心,利用JTAG/SWD下载协议,将存储在FLASH中的程序文件传输至目标板卡的32位单片机。该方案可实现高效、便捷的脱机下载功能。The existing offline downloader has insufficient compatibility with the 32-bit Microcontroller Unit(MCU)of the CKS series.In a computer-free environment,the need for convenient program downloads for 32-bit MCU is more urgent.Especially in the mass production of the production line,it is necessary to download the program efficiently and continuously.In view of the above problems,this paper proposes a design scheme of offline downloader based on CKS32 MCU.In this scheme,the target program file is downloaded through the computer-side host computer software through the USB interface and stored in the FLASH chip external to the CKS32 MCU.With CKS32 MCU as the core controller,it uses JTAG/SWD download protocol to transfer the program files stored in FLASH to the 32-bit MCU of the target board.This solution can achieve efficient and convenient offline download function.
