; @Title: Example for flash declaration of NXP LPC28xx internal flash.
|
|
;
|
|
; @Description:
|
|
; Script arguments:
|
|
;
|
|
; DO lpc28xx [PREPAREONLY]
|
|
;
|
|
; PREPAREONLY only declares flash but does not execute flash programming
|
|
;
|
|
; Example:
|
|
;
|
|
; DO ~~/demo/arm/flash/lpc28xx PREPAREONLY
|
|
;
|
|
; List of LPC28xx derivatives and their configuration:
|
|
;
|
|
; CPU-Type FlashSize RamSize
|
|
; (KB) (KB)
|
|
; -----------------------------
|
|
; LPC2880 - 64.
|
|
; LPC2888 1024. 64.
|
|
;
|
|
; Internal flash is located at: 0x10400000
|
|
; Internal RAM is located at: 0x00400000
|
|
;
|
|
; Small sector size is 8kB. Large sector size is 64 kB.
|
|
;
|
|
; A Flash page is the unit in which the Flash is programmed: 512 bytes.
|
|
; Therefore an alignment of 512 Byte has to be used for flash programming.
