The short of this one is that canboot will retry until success (or a number of failures is exceeded).

Typically this error is lack of termination resistors (i.e. your bus isnt 60Ohms) or an otherwise intermittent connection.

With the U2C 2.1 it can also be due to the implementation of candelight on the G0B1.
