; @Title: Example script for flash declaration of Atmel ATSAM4E internal flash.
|
|
;
|
|
; @Description:
|
|
; Script arguments:
|
|
;
|
|
; DO atsam4e [PREPAREONLY] [CPU=<cpu>]
|
|
;
|
|
; PREPAREONLY only declares flash but does not execute flash
|
|
; programming example
|
|
;
|
|
; CPU=<cpu> selects CPU derivative <cpu>
|
|
;
|
|
; Example:
|
|
;
|
|
; DO ~~/demo/arm/flash/atsam4e CPU=ATSAM4E16E PREPAREONLY
|
|
;
|
|
; List of ATSAM4E derivatives and their configuration:
|
|
;
|
|
; CPU-Type Flash size Page size SRAM size

; [Byte] [Byte] [Byte]

; ATSAM4E8C 0x80000 0x200 0x20000
|
|
; ATSAM4E8E 0x80000 0x200 0x20000
|
|
; ATSAM4E16C 0x100000 0x200 0x20000
|
|
; ATSAM4E16E 0x100000 0x200 0x20000
|
|
;
|
|
; The internal flash is located at 0x00400000
|
|
; The internal ROM is located at 0x00800000.
|
|
; The internal SRAM is located at 0x20000000
|
|
;
|
|
; The system always boot at address 0x0. If GPNVM bit 1 is set the
|
|
; internal flash is mirrored to address 0x0 otherwise ROM is mapped
|
|
; 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 atsam4-nvm.cmm script.
