基于TMS320C6713B的远程软件加载设计与实现

摘要

To get rid of length limitation of the JTAG debug cable in an embedded system based on TMS320C6713B,a software uploading method through RS422/485 is required.Design of realizaing software uploading and BOOTLOAD based on RS422/485 Bus is provided in this paper.Implement of remote software uploading System based on C6713B is described detailedly in both hardware and software aspects.Software uploading System's design is achieved with new characteristic such as DSP/BIOS configuration,EMIF bus and large-capacity SDRAM.Thus requirements of high throughout and fast transmission are satisfied.%针对以TMS320C6713B为核心的某嵌入式系统要求通过RS422/485进行系统应用软件的加载与固化,摆脱JTAG口调试电缆的长度限制的问题,描述了一种采用RS422/485进行软件加载与BOOTLOAD的设计方法,从硬件设计、软件设计两大方面说明基于C6713B的远程软件加载系统的实现,对TMS320C6713B使用DSP/BIOS配置、EMIF总线外挂大容量SDRAM等一些新特点进行软件加载系统的设计,从而满足了嵌入式系统对远程加载软件大数据量,快速传输的要求.
