; @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.
