flashblink.cmd

ti dsp 5510 的BOOT程序。利用此程序实现将代码写入到FLASH 的功能。

/* File         :    board.lcf

   Description  :    C55XX EVM communication kernel link loader control file. 

   Targets      :    TMS320C55XX.

   Conditions   :    None.

   Author       :    Kwame Kyiamah.

   Distribution :    None

   Restrictions :    The memory definitions MUST be preserved: VECTORS, XFER, SCRATCH, XFERHDR 
                     and FIFO. FIFO is important for proper function of the HPI 
                     implemented fifo.
