摘要:

采用JTAG仿真器完成DSP应用程序代码烧写的方式不适用于工程现场应用中,在线烧写技术已被广泛运用,但是一般在线烧写的过程需要调试PC机与DSP板通过串口直接相连实现,而在某些
特殊的工程现场不具备此条件。本文对此提出一种借助VxWorks系统间接连接调试PC与DSP板实现程序烧写的方法,为特定工程现场提供了DSP程序烧写的一个新解决方案。

Abstract:

In conventional methods, JTAG simulators are applied to the burning of programs, which is proved inefficient and inconvenient in the aviation engineering
settings. The technique of online writing flash has been widely used, which needs that DSPs connecting to PC directly, but some special site cannot provide this connection.
Based on network communication in Vxworks, a new design is proposed to realize online writing flash for DSPs even without direct connection to PC.
