; @Title: AT91SAM9XE Serial FLASH Programming Script
|
|
; @Description:
|
|
; Serial FLASH (ST, 25P64) is connected the SPI0 (Serial Peripheral Interface)
|
|
; or Serial Data FLASH (ATMEL, AT45DB642D) is connected the SPI0
|
|
;
|
|
; Internal SRAM : 0x300000
|
|
; Serial FLASH Controller Addr: 0xFFFC8000
