Re: [beagleboard] Use PWM and UART at the same time

Theodosis, did you get it to work? I have a small test.sh file containing #!/bin/bash config-pin P9.11 uart I tried both, systemd and rc.local, but in both cases i get "P9_xx pinmux file not found". If I run the script after logging in everything works fine. Am Dienstag, 8. November 2016

Re: [beagleboard] Use PWM and UART at the same time

I tried twice to implement my own overlay but I gave up because I had a significant lack of knowledge at this point. Finally i used cape-universala (in which pwm works fine) and enabled uart2 and uart4 pins by using config-pin. Now it works! (hope nothing else has broken!) Thank you very much!

Re: [beagleboard] Use PWM and UART at the same time

So if this continues to be a problem for you. Once you unload a cape, you should instead just reboot. This is not ideal, but it's what we have right now . . . On Mon, Nov 7, 2016 at 2:18 PM, William Hermans wrote: > > > On Mon, Nov 7, 2016 at 1:39 PM, Theodosis Ntegiannakis <

Hello, I am developing a ROS project and I am using Ubuntu 16.04.1 on Beaglebone Black with 4.4.23-ti-r51 kernel. I have a setup which uses the following pins: Analog: P9_40, P9_39, P9_38, P9_37, P9_36 PWM: P9_16, P8_13 UART2, UART4 , GPIO: P9_41 In /boot/uEnv.txt I only have the line
