; -------------------------------------------------------------------------------- ; @Title: Generic script for RM42 internal flash ; ; @Description: ; ; Flash declaration of TI RM42 internal flash. ; ; Script arguments: ; ; DO rm42 [PREPAREONLY] [AUTOECC=0|1] [DUALPORT=0|1] ; ; PREPAREONLY only declares flash but does not execute flash programming ; ; AUTOECC default value is 1 ; ; DUALPORT default value is 0 (disabled). If DualPort mode is enabled ; flash algorithm stays running until flash programming is ; finished. Data is tranferred via dual-port memory access. ; ; For example: ; ; DO ~~/demo/arm/flash/rm42 DUALPORT=1 PREPAREONLY ; ; List of RM42 derivatives and their configuration: ; ; EEPROM ; Program emulation ; CPU-Type Flash Flash RAM ; -------------------------------------------------------------------------------- ; RM42L432 384kB 16kB 32kB ; ; HINTS: ; ; Flash programming algorithm is linked to address 0x08000000 and is not ; position independent. Code address of FLASH.TARGET command has not be ; changed. ; ; OTP sectors can be programmed using FLASH.Program with /OTP option. ; For example with: ; ; FLASH.Program 0xF0000000--0xF0000FFF /OTP ; Data.Set ... ; ... ; FLASH.Program off ; ; @Chip: RM42* ; @Author: WRD ; @Copyright: (C) 1989-2022 Lauterbach GmbH, licensed for use with TRACE32(R) only ; -------------------------------------------------------------------------------- ; $Rev: 10516 $ ; $Id: rm42.cmm 10516 2022-02-02 11:39:30Z bschroefel $ ; ; ------------------------------------------------------------------------------ ; Setup script configuration.
