Half past nine

Hi ARM,

    Hi Frank,

    Flash : Store CRC of the executable in Flash while loading. The same can be checked at runtime by re computing the CRC of the executable and compare against the CRC  that is stored in the Flash.

     RAM:keep a pattern e.g. A5A5 in two locations at startup, later at runtime compare the both copies have same value.
