The XpressNet implementation dictates to use 62500Baud, which is fine when using a 10MHz clock for the AVR (3.3V) and using 9 as UBRR value.
On the other side (Linux), AFAIK only the traditional baudrates (9600, 19200, ... , 115200 etc) are available. These rates are not exactly producible when using a 10MHz crystal.
I cannot change the XpressNet parameters (devices on the market). I don't know if the BBB can use non-standard baudrates.
How can I generate traditional baudrates using a 10MHz crystal?
