摘要
在以DSP为CPU的嵌入式系统软件开发中,常常需要对目标机软件进行升级更新,一般的方法是利用仿真器通过DSP上的JTAG端口对目标机软件进行调试后烧写,这种方法操作复杂,常用在软件开发阶段。文中设计了一种利用计算机串口与目标机串口实现对DSP软件下载的方法,并且对软件下载过程和软件加载过程进行了比较详细的设计说明。这种方法不需要仿真器和JTAG端口即可方便地实现目标机的软件下载更新。
In the embedded systems based on DSP, the software update is usually needed. The common update method in software development phase is fairly complex, which uses the emulator to debug and load software on DSP through JTAG port. A software downloading method by serial port of computer and DSP is designed, and the software downloading and boot loading process are described detail. This method can easily update software on DSP without emulator and JTAG port.
