摘要
在以DSP为核心的飞行器控制系统使用和维护过程中,经常需要对其嵌入式软件进行在线升级。通过JTAG接口进行软件升级的方式在飞控组件装机后变得非常不方便。研究了通过串行接口进行飞控软件在线升级的方法,基于DSP多次加载方案和双重校验机制在TMS320C6713B DSP系统上实现了飞控代码远距离、可靠的烧录和自启动,验证了方法的有效性。
The online upgrade is always needed for embedded control software in the process of using and maintaining a DSP-core flight control system.One way of software upgrade is realized by Joint Test Action Group（JTAG） interface, but this method has great inconvenience after flight equipment assembled. This paper studies an online upgrade method for flight control software through serial interface.Based on DSP＇s multiple loading design and double checking mechanism,the code is burned and self-started remotely and reliably on TMS320C6713B DSP system,and the availability of this method is proved.
