How run program automatically for MPC5554 after Reset or Power On

Bahus · ‎07-09-2007

I work with Wind River Workbench 2.6

I does:
    1. Load program in Internal Flash (0x00004000)
    2. Write RCHW (0x065a) at 0x00004000, because main() placed 0x00004030
    3. Power off
    4. Power on

Program don`t run.
Why?
How work Boot Assist Module Program?
Please help...

P.S
    The Program is correct (running on target by Workbench)

I'm not familiar with using WorkBench but I suspect you can launch the debugger and have the MPC5554 stop at the RESET vector (don't run any initialization code) then read the various registers configured by the Reset Configuration Word data to make sure these registers are indeed getting set properly. If they are getting set properly, start stepping through your code in flash and see how far you get, but if these registers are not set properly then review your method for programming the RCHW.
