This code is used to read the boot flash of the DBAU1200 Development Board and save it as the SREC format.

Cflashamilton is mainly used to read boot flash, this class can be obtained here: http://blog.csdn.net/norains/archive/2008/05/31/2498178.aspx

Note that the Code listed in this article is the reference code, and there are still many imperfections. For example, the size of the FLASH to be read must be an integer multiple of 16. Be careful when using it.

// Start address of the dbau1200 Development Board flash
