MPC5567: word based Flash programming routine

emmemondo — Fri, 11 Sep 2009 22:38:41 GMT

Hi,

I am developing a routine to write a single word in internal flash.

I've tryed the following code but it doesn't work:

//The sector is already unlocked

t_WORD *pa;

pa = (t_WORD *)0xA0000; //High Memory, sector 1

  FLASH.MCR.B.PEAS = 0;
  FLASH.MCR.B.PGM = 1;
*pa = 0xCAFE;   // Data Interlock Write
  FLASH.MCR.B.EHV = 1;
   while(!FLASH.MCR.B.DONE)
     {
       ;
     }
     FLASH.MCR.B.PEG = 1;
     FLASH.MCR.B.EHV = 0;
     FLASH.MCR.B.PGM = 0;

...

The question is that if when the "data interlock" instruction an EXCEPTION IVOR2 arise and the system hang.

What's wrong with the code above?

Thanks to all,

emme

Hi,

I have exactly the same problem (to erase and program the internal flash).

I work on the MPC5554 but the problem is the same.

Did you find the solution?

Thank you.

You can go to ecu.zeeff.com to find some working flash writing code.
