    When you're using the bootloader, make sure you have DEFINE LOADER_USED 1 at the top of your code. The syntax must be exact and in CAPITAL letters, unless, yes it may give you some weird results.

    Now, did you tried with a simple led Blink?

    Does the Bootloader return any error messages?

    Did you use the same schematic as stated in the MCS help-file?


    Are you using Mecanique bootloader or another one?

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.
