摘要: 提出了一种通过CAN Bootloader引导程序实现TMS320F28335应用程序升级的方法。TMS320F28335配置为Jump to Flash启动模式,通过预烧写CAN Bootloader引导程序,将上位机通过CAN总线下发的BIN升级程序文件烧写至指定Flash区域,并引导应用程序启动,实现程序在线升级功能。详细介绍了该方法的实现原理以及开发过程。通过试验,证明该方法稳定可靠,实用性强。

Abstract: A method of TMS320F28335 program update by CAN bootloader is proposed. To realize the method of program update, the TMS320F28335 boot mode is configured as “Jump to Flash”, and the binary update file transmitted by CAN bus from PC through the pre-burned bootloader program is downloaded, and the program to start is guided. The realization principle and the development process of this method are introduced. The experimental result indicates that this method is stable, reliable and practical.

Key words: DSP, TMS320F28335, CANbus, BINfile, bootloader
