+/* @Note
+ * CD-ROM Example:
+ * 1.This program provides examples of CD-ROM.The iso file TEST.iso used for testing is 
+ * located in the TEST_ISO folder. 
+ * 2.User needs to place the ISO at address 0 of the external Flash.The ISO file is in 
+ * ISO 9660 Joliet Level 1 format and is suitable for a sector size of 512B. If other 
+ * file systems are used, the sector size DEF_CFG_DISK_SEC_SIZE in the program needs to 
+ * be adjusted.
+ * 3.This Code Only Supports Winboard W25 Series flash, if user needs to use other type
+ * of flash, you can add flash type by yourself in SPI_FLASH.c in user floder.
+ * 4.External flash chip needs to be attached to SPI_1.
+ * 5.CD_ROM iso file 'TEST.iso' contains wch serial-port driver, and autorun.inf.
