基于CCS的DSP片外Flash直接烧写设计

Design of direct programming based on CCS DSP external Flash

要可靠启动DSP系统中用户代码,关键是Flash正确可靠烧写。提出了一种基于CCS简单、容易理解的直接烧写方法。通过恰当设置COFF代码段,保存运行地址必需的DATA,以在线编程的方式将保存的DATA烧写到外部Flash中。采用TMS320C6711 DSP试验板,对Flash烧写上电加载后,DSP能够正确、稳定的运行。给出了直接烧写方法,操作简便,容易掌握,为DSP系统中Flash的烧写提供了一条有效解决途径。

To reliably start user code in DSP systerm, FLASH accurately and reliably burning is the key. This article proposed a direct programming method which is simple and esay to understand based on CCS. This method is setting the COFF code segment reasonably,saving the required DATA on the running address,then,bum the saved DATA to the external FLASH by the way of online programming.Based on TMS320C6711 DSP trial board,burned the FLASH using this method,power on,when the program onload finished,the DSP can correctly and stably run.The direct programming method is given,The method operation is simply,easy to catch, an effective solution to FLASH programming in DSP system is provided.
