    Hello Nilesh,

    I do not understand what you are asking exactly.  What do you mean you want to put an array into unused flash?  If you have a (constant) array, just link it to flash in the linker command file (e.g., the .const section).

    Are you asking about how to fill the unused flash with a particular value?  If so, know that 0xFFFF (the state of erased flashed) is already an ILLEGAL instruction on the C28x and will trigger the ILLEGAL ISR.

    Regards,

    David
