ARM外围FLASH 以及SDRAM烧写程序 完整的程序 可能对大家硬件编程有点帮助

The GraphicAnimation project is a program for the AT91RM9200
using Atmel AT91RM9200-EK Evaluation Board.

Example functionality:                                                   
 - Displays Animation of ARM, in 3D, to VGA display

The Blinky program is available in different targets:
  RM9200 Ext Flash: configured for external Flash
                    (used for production or target debugging)
  RM9200 Ext RAM:   configured for external RAM (SDRAM)
                    (may be used for target debugging)

Warning !!! IF "RM9200 Ext Flash" IS SELECTED AS TARGET AND PROGRAM 
            IS DOWNLOADED TO EXTERNAL FLASH THE U-BOOT BOOTLOADER 
            WILL BE OVERWRITTEN

Notes: 
  - If "RM9200 Ext Flash" is used as target jumper J15 should be 
    in position EXT (pins 2-3)
  - For "RM9200 Ext RAM" target jumper position is irrelevant as
    those targets are used for debugging and program is loaded to
	External SDRAM using debugger scripts (.ini file) and started
