C6747系统中AIS Nor Boot问题

Other Parts Discussed in Thread: TMS320C6745, TMS320C6747, OMAP-L137

系统中c6747,2Mx16bit Nor Flash(M29W320DB),128M SDRAM, 可参考”SPRS377B TMS320C6745/6747 Floating-point Digital Signal Processor” 中的Figure 6-13。应用程序大约100K左右,采用Nor Boot方式,

 

根据TI的文献sprabb1b “ Using the TMS320C6747/45/43 Bootloader“,有三种方式” Legacy NOR boot,Direct NOR boot,AIS NOR boot,我想采用AIS NOR boot(片选cs2),现在有以下问题:

  1. 把应用程序Bin文件写到nor flash ,开始地址0x60000004,但boot不成功,不知什么问题?
  2. sprabb1b 中17页第6节“For booting from a NOR Flash, a configuration word is required before AIS as shown in Figure 3. NOR Flash should be connected to EMA_CS[2] of the EMIFA peripheral.”,这个configuration word如何配置,他的地址是多少?
  3. 对于AIS boot模式是否不需要再编写bootloader程序?Nor flash直接运行?
  4. 通常情况下AIS Nor boot的具体步骤及流程如何?有没有例程?

 

 

谢谢!
