    HI Andy !

    I just need to check if programm codes in flash was not changed. I have found 2 examples - with all flash checksum (with trash) and only code section checksum (more compact). So I just ask what should I prefer. I have no precise Requirement.

    I have no experience in checksum calculation so I ask your opinion. My be someon can post ITS working example for 166. It will be nice :)
