摘要
在嵌入式系统中,经常要求上电后系统能自动把程序从DSP外部的ROM加载到片内RAM执行。给出一种基于TMS320C6701 DSP的ROM加载方案,通过配置CCS中DSP/BIOS模块的参数实现DSP程序中代码和数据段的先后分开加载,比传统的由手动编写连接命令文件(.CMD)实现自动加载更为方便。在此基础上,设计并实现了用CCS直接对FLASH芯片进行在线烧写。实验证明,该DSP加载方案稳定可靠,且易于实现。
The program code needs to be loaded from external ROM to internal RAM in embedded system when it is switched on. A method of ROM bootload based on TMS320C6701 DSP is presented, which implements code and data section loading dividually by configuring the DSP/BIOS module in CCS, then a method of FLASH online programming with CCS is presented. The feasibility and conveniency of this bootload method are verified.
