    Hi,

    When exactly is this error shown? Does this happen when you are trying to look at the contents of the pointer in the watch window?

    According to the OMAPL138's datasheet, the address 0x00000000 has nothing mapped to it, therefore if the pointer inadvertedly has zero as its value then CCS will throw an error as the memory is invalid. 

    If that is not the scenario, maybe a screen capture could help figure out what may be happening.

    Regards,
