Hi, We've been using the BBB for a year or so now do act as webserver and a gateway to a zigbee based network. We have developed a cape that contains a zigbee device that we can easily communicate with through one of the UARTs.
We have had a working setup using the old April 2014 image that the BBB came shipped with, this needed to be brought up to date and I have been developing new software with the January 2016 image and a USB based zigbee device. My trouble is, now I have come to test the software using the cape I cannot seem to enable the UARTs. In my 2014 version I followed the instructions on this page: http://beaglebone.cameon.net/home/serial-ports-uart and this work successfully. After "some" digging I found out about the config-pin application here: https://github.com/cdsteinkuehler/beaglebone-universal-io and have checked the help page of the app. I had hoped this would solve the problem and tried to set the use of pins I wanted (to enable UART5) however I got an error message that there was no pinmux file. Having re-read the above page I don't have half the directory structure that the instructions talk about, namely no ocp.* in /sys/devices/, so I'm completely stuck. I just need to know how to enable UART5, I'm a fairly experienced linux user and very experience programmer, though my knowledge of Linux kernal stuff is terrible. I also have a strange setup in my /dev/ for ttyO* I had expected there only to be ttyO0 as that was the only port enabled by default, is that still the case? /dev# dir -l ttyO* lrwxrwxrwx 1 root root 5 May 25 14:30 ttyO0 -> ttyS0 lrwxrwxrwx 1 root root 5 May 25 14:30 ttyO1 -> ttyS1 lrwxrwxrwx 1 root root 5 May 25 14:30 ttyO2 -> ttyS2 lrwxrwxrwx 1 root root 5 May 25 14:30 ttyO4 -> ttyS4 My Linux knowledge is also failing me here are these showing symbolic links? I'm not sure if this is part of why I can't use the UARTs or something separate. Sorry for the long post with a couple of problems in it.
