    Hi Krushna,

    A flash word is 64 bits, which means you'll need to address on the 64 bit boundaries (8-bytes) in order to write consecutively, what you can do is a 64 bit write but mask the bits you do not want to program/overwrite (mask the data with 0xFFFFFFFFFFFFFFFF). 

    So in your code you're programming the Evens then the Odds, the even and odd addresses will have the same memory address with your 4*i, since you are not byte aligned.

    Regards,
    Luke
