; @Title: Example for flash declaration of NXP LPC22xx internal flash.
;
; @Description:
; Script arguments:
;
; DO lpc22xx [PREPAREONLY]
;
; PREPAREONLY only declares flash but does not execute flash programming
;
; Example:
;
; DO ~~/demo/arm/flash/lpc22xx PREPAREONLY
;
; List of LPC22xx derivatives and their configuration:
;
; CPU-Type FlashSize FlashType UserFlash RamSize
; (kB) (kB) (kB)
; --------------------------------------------------------------------------------
; LPC2210 - 0. - 16.
; LPC2220 - 0. - 16.
; LPC2212 256. 1. 248. 16.
; LPC2214 256. 1. 248. 16.
; LPC2290 - 0 - 16.
; LPC2292 256. 1. 248. 16.
; LPC2294 256. 1. 248. 16.
;
; Supported flash types:
;
; FlashType SmallBlock MainBlock BootFlash Alignment
; --------------------------------------------------------------------------------
; 0. no processor internal flash
; 1. 8 kB 64 kB 8 kB 512 B
;
; HINTS:
;
; With Trace32 software version build 17761 or higher and most recent
; flash support package FLASH.CLocK.AUTO can be used for automatic
; flash clock measurement. With older Trace32 software flash module
; input clock has to be set with FLASH.CLocK <freq> command. Flash
; clock has to match System Clock Frequency (CCLK).
;
; Boot flash cannot be programmed or erased with builtin flash
; algorithm.
;
; Data has to be loaded to flash alignment to 512 Byte boundaries.
;
; Vector table checksum generation is done by script, so that it
; can be used or switched off, as needed.
