Enabling pins/ports (uart) on Beaglebone Black A5C with Ubuntu 18.04

[BBB-noob]

Hi!
After many attempts with the various answers already given, I have to resign myself and ask the community for help.

My project uses Ubuntu 18.04 with the kernel 4.14.44-ti-r51 on a Beaglebone Black A5C. Ultimately I am working on ROS but my first goal is to make the pins work properly first, especially by enabling the uart ports for example. I tried the config-pin method, tuning the boot/uEnv.txt file to enable them when booting, loading the beaglebone-universal-io from https://github.com/cdsteinkuehler/beaglebone-universal-io... It seems that in all cases, the pinmux file of the pin I'm trying to change is not found (and I tried several) and that I should verify your device tree file.

I had the same issue on Ubuntu 16.04 and got rid of these issues by switching to Debian 9.3. But now I really need to use Ubuntu (ROS-related) so I would like to have the same possibilities in terms of pins-controlling as with Debian 9.3.

I tried many updates on the file /boot/uEnv.txt but every time, the same error occurs, when I try to set the ports to uart, it give me that:
ubuntu@arm:~$ config-pin P9.11 uart
P9_11 pinmux file not found!
Please verify your device tree file

Right now, /bootuEnv.txt looks like:

Lastly, I tried to display $ cat /sys/devices/platform/bone_capemgr/slots
But the slot file (or whatever this is) does not exist, although I could display something before if I recall correctly.

Thanks a lot in advance for any help you could give me!

@BBB-noob ps i've been posting ROS Melodic Morenia weekly images for awhile now here:

https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#ROS_.28ROS_Melodic_Morenia.29_-_Weekly

Everything is really setup for ROS..

Regards,

[BBB-noob]

@RobertCNelson

Thanks a lot for the answer. Indeed, the already-setup image works perfectly on BBB. I tried it before but now I realised my sd card was dying and could not be read properly. But it worked with a new one.

I was wondering if there was a similar image with Ubuntu 16.04 and ROS Kinetic?
