欢迎光临我的博客首页个人资料日志图片视频(测)好友博客群日志设置f2812 flash配置寄存器的等待周期数的理解
分类:默认栏目一般而言，为了将运行在f2812  
flash内得程序代码以最快速度运行，需要设置flash配置寄存器的等待周期数，而“设置flash配置寄存器的等待周期数”的这段代码是不能在flash内部执行的，这样就会出现两种实际的配置方式：
  
一种是2812系统无外扩程序存储器，此时程序只能写在2812内部得flash区，程序运行开始后，需要将“设置flash配置寄存器的等待周期数”的这段代码用数据复制的方式复制到内部sram区，比如 
L0 区，然后使用跳转指令跳转到L0 
区“设置flash配置寄存器的等待周期数”的代码进行flash配置寄存器的设置，设置完成后再使用跳转指令跳转到flash程序区执行正常的功能程序。这样以后的flash内的代码就会以最快速度运行。

  
还有一种是2812系统外扩了部分“引导”程序存储器，“设置flash配置寄存器的等待周期数”的这段代码放置在外扩的“引导”程序存储器内，而其他的所有程序代码都放在2812内部flash区，系统复位后，首先运行外扩的“引导”程序存储器内的程序，一旦完成了对内部flash配置寄存器的设置后，即跳转到flash程序区执行正常的功能程序。

  正如上述，对2812外部接口XINTF配置寄存器的设置代码，也是不能在“外部”程序代码区进行的，为了实现对其的正常设置，可仿照上述办法进行相关操作。

分类:默认栏目用的是CCS2.20版本提供的SDFLASH,设置好SDFLASH后,主要是要将需要下载的.out文件写进去.
关键在于在线仿真时的cmd文件要加以更换成新的.使用的是:

然后把lib文件替换成:rts2800_fl040830.lib
就可以啦.
希望你也成功!!!
