Flash family code NOP ; is used to protect against unintended erasure or programming. ; ; Up to core revision 0.5 shadow row should not be erased. Flash ; family code NOP is used to protect against unintended erasure ; or programming. ; ; Flash register base address has to be 0xc3f88000, because target ; program does currently not support another base address. ; ; Programming a 32 byte row more than once until next erasure may ; cause bus error on this row. To avoid such problems FLASH.AUTO ; can be used for programming. ; ; @Author: WRD ; @Chip: MPC5554 ; @Copyright: (C) 1989-2017 Lauterbach GmbH, licensed for use with TRACE32(R) only ; -------------------------------------------------------------------------------- ; $Rev: 5830 $ ; $Id: mpc5554.cmm 5830 2018-07-16 15:25:52Z rweiss $ ; LOCAL ¶meters ¶m_prepareonly ¶m_skipconfig ¶m_portsharing ENTRY %LINE ¶meters ¶m_prepareonly=(STRing.SCAN(STRing.UPpeR("¶meters"),"PREPAREONLY",0)!=-1) ¶m_skipconfig=(STRing.SCAN(STRing.UPpeR("¶meters"),"SKIPCONFIG",0)!=-1) ¶m_portsharing=STRing.SCANAndExtract(STRing.UPpeR("¶meters"),"PORTSHARING=","") LOCAL &flashsize &shadowrow &flashdriver &optimize &flashsize="tbd" &shadowrow="no" &flashdriver="tbd.bin" ; Optimize flash programming time by switching on PLL &optimize=0 LOCAL &DualPort IF VERSION.BUILD.BASE()>=45520. &DualPort="/DualPort" ; -------------------------------------------------------------------------------- ; CPU setup IF !¶m_skipconfig ( SYStem.RESet IF "¶m_portsharing"!="" SYStem.CONFIG PortSHaring ¶m_portsharing SYStem.BdmClock 4MHz SYStem.CPU MPC5554 SYStem.Up IF &optimize==1 ( ; setup PLL.
