MCF5223x Flash Speculation in CW V7.0

The setting of FLASHBAR[6] in the default startup code for CodeWarrior V7.0 tools has been removed. As far as I know the Flash address speculation errata bug hasn't been fixed in the MCF5223x family yet. The code was in Ver 6.4 along with the ability to change the Flash address base. With Flash staying at the default address of 0x00000000 the following code needs to be added right near the reset vector:


    move.l  #0x00000061,d0
    movec   d0,FLASHBAR

this is very important!

Also my program did not work for this reason, but with CW V6.3
