Sounds like to me your boot reset vector fuses are set incorrectly,
probably jumping to after where you have you boot loader stored.

If you think your boot size is correct, then change it to all possible
options and try again.

Lastly check where the bootloader determins to exicute the bootloader
or main app, it could always be exicuting the main ap depending on
what it is checking.
