; @Title: Example for flash declaration of Atmel AT91SAM7A3 internal flash.
|
|
;
|
|
; @Description:
|
|
; Script arguments:
|
|
;
|
|
; DO at91sam7a3 [PREPAREONLY]
|
|
;
|
|
; PREPAREONLY only declares flash but does not execute flash programming
|
|
;
|
|
; Example:
|
|
;
|
|
; DO ~~/demo/arm/flash/at91sam7a3 PREPAREONLY
|
|
;
|
|
; The flash is divided into pages of 256 Byte.
|
|
;
|
|
; 256 kByte internal flash at 0x00100000
|
|
; 32 kByte internal SRAM at 0x00200000
|
|
;
|
|
; Beginning at address 0x0 is located internal flash before remap command
|
|
; or internal SRAM after remap command.
|
|
;
|
|
; HINTS:
|
|
;
|
|
; Locked pages can be unlocked with FLASH.UNLOCK command and can be
|
|
; locked again with FLASH.LOCK command.
|
|
;
|
|
; Watchdog is critical for flash programming. The flash algorithm is
|
|
; serving the watchdog if the watchdog is not used in window mode.
|
|
;
|
|
; If the watchdog is setup to window mode by a running application
|
|
; the watchdog should be either disbaled after first power-up or the
|
|
; board should be power-up before every flash programming. If the
|
|
; watchdog is disabled after power-up it cannot be enabled again by
|
|
; the application because WDT_MR register is write once. Please see
|
|
; below the command to disable the watchdog.
