  There are actuallly several uarts in the BBB. You don't have to use 0. But there are some constraints and cofiguration that needs to be done to get the others working. Unfortunately things have changed in different kernel versions. I gave you some links to look at below but I am sure they will make you more confused then when you started. I wish this whole mapping thing was more straight forward. Maybe someone else has done this on the current version and could help. I suspect you will want to use one of the other uarts which are available on the BBB.

Subject: [arm-allstar] Disabling serial port debug console

Greetings, BeagleGeniuses.
In an earlier thread, Doug helped me install minicom on my BBB. Now, I'm able to reliably access my serial console on other devices with a PL203 USB-serial adapter.  

I'd like to use the BBB's onboard serial header instead of the USB adapter. Problem is, I'm to simple to figure out how to properly disable the BBB's default setting that dedicates the onboard serial header for a boot/system debugging serial console for the BBB. 
In earlier discussion, Doug referenced the below article as a start to learning how to use the onboard console, but again, I was too simple to understand how to disable the boot console/system console defaults so the port can be released to minicom. 


I'm sure the answer will be another one-liner, but could probably be helpful for other simple people. 
Thanks for reading and 73
