针对脱离调试器下，DSP远程软件维护和升级问题，从TI C6000系列DSP程序自加载原理出发，提出了一种基于简单文件传输协议（TFTP）和可用于无操作系统平台的程序远程更新方案，给出了系统软件设计结构，重点设计了程序加载更新的过程，并通过移植轻型TCP/IP协议栈（LwIP），实现了网络协议在DSP平台下的高效稳定嵌入。工程实践表明，该方案优化了网络协议对系统资源的开销，提高了DSP下以太网功能开发的灵活性，有益于系统性能的提升和改进。

In view of remote software maintenance and update of DSP without debugger,a scheme of remote update for DSP program which is based on trivial file transfer protocol(TFTP)and can be applied to a platform without operation system is pro-posed according to bootloading principle of TI C6000 series DSP. A hierarchical structure of system software design laying em-phasis on the procedure of program loading and updating is presented. High efficiency and stability embedding of the network protocol is realized in DSP platform by transplanting the lightweight TCP/IP stack (LwIP). Project practice indicates that the scheme optimizes the expense of system resource from network protocol,improves the flexibility of Ethernet development on DSP,and is beneficial to promote the system performance.
