While working on the a80 target adapter, we observed
that the BTnode may send undefined data right after
initialization of the UART.

    is this the first usage of the uart?
    is it more than one byte?

    I found a weird line in the bootloader which prints out an
    error message to the debug UART (if the baudrate is
    different, it would complain the undefined data) instead
    notify with the leds. It is fixed in CVS HEAD
    (http://btnode.cvs.sourceforge.net/btnode/btnut/app/bootloader/bootloader.c?r1=1.25&r2=1.26)...
