DSP2812 FLASH烧写

1、dsp2812 flash烧写 1. 一定要下载最新的flash烧写插件，可以避免很多奇怪的错误出现，这一点非常重要，本人就是在此问题困扰了一整天。 名称是： c2000-211.00-sa-to-ua-ti-flash2x.exe 我使用的产品版本号为2.02.001 2. 下载烧写flash配套cmd文件、lib文件以及起始代码asm文件。 cmd文件名称：dsp281x_headers_nonbios.cmd cmd文件名称：f2812.cmd lib文件名称：rts2800_ml.lib asm文件名称：dsp281x_codestartbranch.asm 另外在ram调试时用以下两

2、个文件： f2812_ezdsp_ram_lnk.cmd dsp281x_headers_nonbios.cmd 附件给出了2个cmd文件、asm文件、lib文件以及c文件。 其中c文件仅仅作为大家参考。 3. 配置c文件 配置好主程序的c文件，才能将flash成功烧录，并且将flash中的文件拷贝到ram中运行。 关于c文件的配置。 首先在f2812.cmd文件中，我们可以看到有关于加载flash到ram的内容： ramfuncs : load = flashd, run = raml0, load_start(_ramfuncsloadstart), load_end(_ramfuncsl

3、oadend), run_start(_ramfuncsrunstart), page = 0 以及在c文件中调用flash 到ram的函数memcpy，将它放在系统初始化（initsystem();）之后即可： initsystem(); memcpy( initflash(); 所以，我们需要定义所用变量： extern uint16 ramfuncsloadstart; extern uint16 ramfuncsloadend; extern uint16 ramfuncsrunstart; 我的这些定义都是：dsp281x_globalprototypes.h 当中,当然，也可以放在

4、其他系统初始化的地方。 memcpy这个函数应该是rts2800_ml.lib库文件中自带的，不需要我们定义。 关于flash的初始化配置initflash(); 我把它放置在memcpy函数之后。 关于ramfuncs，则在系统初始化中定义即可。如:sysctrl.c中 #pragma code_section(initflash, 另外，许多朋友没有注意需要定义自己其他子程序，导致最终运行的主程序还是在flash中，比如你需要运行的子程序abc，则需要定义#pragma code_section(abc, 烧写成功后的注意事项： 1 一定要拔除仿真器（jtag端），给电路板重新上电，方能实

5、现flash启动。 2 注意mp/mc引脚的电压。0为方式mc来作为计算机模式启动，3.3v为方式mp作为微处理器模式启动。 3 由于gpio引脚的f4f12f3f2决定了dsp2812的启动顺序，而从flash必须要在f4（scitxda）为1，而f12f3f2随意的状态下启动。请大家启动前确认f4引脚电压。 /* / ti file $revision: /main/4 $ / checkin $date: july 9, 2009 17:39:29 $ /# / / file: dsp281x_headers_nonbios.cmd / / title: dsp281x peripher
