; @Title: Example for flash declaration of Atmel AT91SAM3U internal flash.
|
|
;
|
|
; @Description:
|
|
; Script arguments:
|
|
;
|
|
; DO at91sam3u [PREPAREONLY]
|
|
;
|
|
; PREPAREONLY only declares flash but does not execute flash programming
|
|
;
|
|
; Example:
|
|
;
|
|
; DO ~~/demo/arm/flash/at91sam3u PREPAREONLY
|
|
;
|
|
; List of AT91SAM3U derivatives and their configuration:
|
|

|
|
; CPU-Type Flash size Page size SRAM0 size SRAM1 size
|
|
; (Byte) (Byte) (Byte) (Byte)

|
; AT91SAM3U4E 2 * 0x20000 0x100 0x8000 0x4000
|
|
;
|
|
; The flash is divided into pages of 256 Byte.
|
|
;
|
|
; The internal flash EFC0 is located at 0x00080000
|
|
; The internal flash EFC1 is located at 0x00100000
|
|
; The internal SRAM0 is located at 0x20000000
|
|
; The internal SRAM1 is located at 0x20080000
|
|
; The internal ROM is located at 0x00180000.
|
|
;
|
|
; The system always boot at address 0x0. If GPNVM bit 1 is set the
|
|
; internal flash is mirrored to address 0x0 before remap command.
|
|
; Otherwise ROM is mapped to address 0x0. If GPNVM bit 2 is set
|
|
; flash 1 is used for boot otherwise flash 0. 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 disabled 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 at91sam3-nvm.cmm script.
