I am trying to establish communication using the UART on the BBBW (brand new from the box, loaded with Debian 8) but no luck so far. I am familiar with the BBB having a bone cape manager and the necessity to export an overlay. It does not seem to be the case on the BBBW and the command “ls /dev/ttyO*” displays 5 devices.
I did a simple test using minicom (command “minicom -b 9600 -o -D /dev/ttyO1”), wiring P9_24 to P9_26 (UART1) typing characters from the keyboard but no transmission. I tried wiring P9_13 to P9_11 (UART4) and got the same negative result.
I would really appreciate if someone could advise. Thank you very much,
