摘要
文中对TI公司的TMS320C6000系列DSP(数字信号处理器)的Flash引导方式进行了研究,详细阐述了DSP Flash引导模式的实现原理及引导过程,链接命令文件的编写,和如何实现基于第二Bootloader的Flash引导。在实际工程应用中,以TMS320C6202B型DSP和SST39VF800A型Flash为目标系统,根据实际使用经验,由浅入深,从简单到复杂,着重强调了C6X0X与其它C6000芯片在内部存储器结构上的不同而导致Flash引导上的差异,并编写了相应的汇编代码程序,成功实现了基于复制表的第二Bootloader Flash引导,系统运行稳定可靠,表明了该引导方法行之有效。
Flash boot of TI TMS320C6000 family is studied in this paper. The implementation principle of DSP Flash boot mode , the boot process, the writing of linker command file and how to achieve the Flash boot based on the second Bootloader are described in detail. In practical engineering applications, taking TMS320C6202B DSP and SST39VF800A Flash as the target system, basing on actual experience, from the easy to the difficult and complicated, the differences in internal memory structures between C6XOX and other C6000-chip which led to the Flash boot differences are emphasized. Not only the corresponding assembly code program is written, but also Flash boot is successfully accomplished with the second Bootloader based on the section copy table. The system is stable and reliable, showing that the boot method is effective.
