Hi,

The compiler does not accept a baud rate that has more than a 3% error. We updated
our calculations so instead of rounding to the nearest percent we look at the fraction
as well. Your example has a 3.1% error. The older version was taking up to a 3.5% error.

You can still get it to compile by asking for a baud rate of 111600. There will be no error
and you will get the same baud rate as you were getting with the older version (as close
as the part can get to 115200 at 25mhz).
