I would make sure that the Analog device IC has the output TX connected to
the TX on the Ext. Board and the input RX to RX. I wish I had a nickel for
every time I saw the DTE (Data Terminal Equipment) and DCE (Data
Communications Equipment) swapped.
It would be helpfull to probe the RX and TX line to see if there is
activity on it using a logic analyzer or o-scope. This will let you verify
the TX/RX and baud rates of the two devices. I did not have to change
any configuration or enable anything to get the UARTS working using
Bonescript commands on my two Rev C BBB's. I have a simple HTML/Java app
that you can point to from Chrome to send out data bytes on the UART if you
want that let me know, I havn't gotten to the receive part of my app yet.
I am probably less experienced than you with software so this is the only
way I got the UARTs working.
