; @Title: Example for flash declaration of Atmel AT91SAM7SE internal flash.
;
; @Description:
; Script arguments:
;
; DO at91sam7se [PREPAREONLY]
;
; PREPAREONLY only declares flash but does not execute flash programming
;
; Example:
;
; DO ~~/demo/arm/flash/at91sam7se PREPAREONLY
;
; List of AT91SAM7SE derivatives and their configuration:
;
; CPU-Type FlashSize Pagesize SRAM size Algorithm
; (Byte) (Byte) (Byte)
; --------------------------------------------------------------------------------
; AT91SAM7SE32 0x8000 0x80 0x2000 efcs.bin
; AT91SAM7SE256 0x40000 0x100 0x8000 efcs2.bin
; AT91SAM7SE512 0x80000 0x100 0x8000 efcs2.bin
;
; The flash is divided into pages of 128 or 256 Byte. For derivatives
; with 128 Byte sectors the flash algorithm binary efcs.bin has to be
; used. For derivatives with 256 Byte sectors the flash algorithm
; binary efcs2.bin has to be used.
;
; The internal flash is located at 0x00100000.
; The internal SRAM is located at 0x00200000.
; The internal ROM is located at 0x00300000.
;
; If GPNVM bit 2 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 at91sam7-nvm.cmm script.
