    When cross-posting (ie, posting the same question to multiple forums), always include links between the threads.

    Otherwise you waste people's time as they give an answer in one thread - not knowing that it has already been given in another.

     on the Keil forum.

    OK, so I should have spelled it out to you at that point.

    Perhaps you should explain what exactly are you trying to achieve. What are you using the flash to store? How big is the data structure? How often does it change?
