; @Title: Example for flash declaration of Atmel AT91SAM9XE internal flash.
|
|
;
|
|
; @Description:
|
|
; Script arguments:
|
|
;
|
|
; DO at91sam9xe [PREPAREONLY]
|
|
;
|
|
; PREPAREONLY only declares flash but does not execute flash programming
|
|
;
|
|
; Example:
|
|
;
|
|
; DO ~~/demo/arm/flash/at91sam9xe PREPAREONLY
|
|
;
|
|
; List of AT91SAM9XE derivatives and their configuration:
|
|
;
|
|
; CPU-Type FlashSize Pagesize SRAM size Algorithm
|
|
; (Byte) (Byte) (Byte)
|

|
|
; AT91SAM9XE128 0x20000 0x200 0x8000 eefc.bin
|
|
; AT91SAM9XE256 0x40000 0x200 0x8000 eefc.bin
|
|
; AT91SAM9XE512 0x80000 0x200 0x8000 eefc.bin
|
|
;
|
|
; The flash is divided into pages of 512 Byte.
|
|
;
|
|
; The internal flash is located at 0x00200000.
|
|
; The internal SRAM is located at 0x00300000.
|
|
; The internal ROM is located at 0x00100000.
|
|
;
|
|
; If GPNVM bit 3 has value of 1 the internal flash is mirrored to
|
|
; address 0x0 before remap command. Otherwise ROM is mapped to
|
|
; address 0x0. After remap command internal SRAM is mirrored to
|
|
; address 0x0.
|
|
;
|
|
; 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.
|
|
;
|
|
; GPNVM bit values can be changed via at91sam9-nvm.cmm script.
