Hi All.
Thanks for the replies.
I managed to get it working with your help:
1. Make sure RX on serial device points to UARTX TX and TX on serial device
points to UARTX RX.
2. nano /boot/uboot/uEnv.txt add "optargs=capemgr.enable_partno=BB-UART1"
or alternatively add a systemd service (I'm running Debian) to execute the
command "echo BB-UART1 > /sys/devices/bone_capemgr*/slots"
3. to make sure this succeeded:
run : ls /dev/ttyO* - you should see ttyO1
run cat /sys/devices/bone_capemgr*/slots - you should see BB-UART1
added to the output.
This pretty much enabled UART over serial for me.
