				// This file contains the constant information for the Application Image

				// For initial download, uncomment '0xff' line, download to the target, and 
				// use the "O" command to calculate the correct CRC.  Once known, comment out 
				// the 0xFF line, and uncomment the following line, replacing the contents 
				// with the value returned from the "O" command, but LSB-first.
				// For example, if "O" returned 73f89dcd,
				// the byte order would be { 0xcd, 0x9d, 0xf8, 0x73 }
