Hello there, I am attempting to activate UART pins on the BeagleBone Black with Ubuntu 16.04 kernel 4.4.68
ubuntu@arm:~$ uname -a Linux arm 4.4.68-ti-r111 #1 SMP Wed Jun 28 13:40:31 UTC 2017 armv7l armv7l armv7l GNU/Linux I have tried editing the /boot/uEnv.txt file. cape_enable=bone_capemgr.enable_partno=BB-UART1 I have tried echo BB-UART1 > /sys/devices/platform/bone_capemgr/slots Which causes the BBB to stall, I even let it sit for almost 2 hours once to no results. ubuntu@arm:~$ ls -l /dev/ttyO* lrwxrwxrwx 1 root root 5 Jul 14 14:48 /dev/ttyO0 -> ttyS0 lrwxrwxrwx 1 root root 5 Jul 14 14:48 /dev/ttyO1 -> ttyS1 lrwxrwxrwx 1 root root 5 Jul 14 14:48 /dev/ttyO2 -> ttyS2 lrwxrwxrwx 1 root root 5 Jul 14 14:48 /dev/ttyO4 -> ttyS4 ubuntu@arm:~$ ls -l /dev/ttyS* crw--w---- 1 root tty 4, 64 Jul 14 14:48 /dev/ttyS0 crw-rw---- 1 root dialout 4, 65 Jul 14 14:48 /dev/ttyS1 crw-rw---- 1 root dialout 4, 66 Jul 14 14:48 /dev/ttyS2 crw-rw---- 1 root dialout 4, 67 Jul 14 14:48 /dev/ttyS3 crw-rw---- 1 root dialout 4, 68 Jul 14 14:48 /dev/ttyS4 crw-rw---- 1 root dialout 4, 69 Jul 14 14:48 /dev/ttyS5 I have tried config-pin 911 uart config pin 913 uart ubuntu@arm:~$ config-pin -q 911 P9_11 Mode: uart ubuntu@arm:~$ config-pin -q 913 P9_13 Mode: uart But still no data being transferred. My end goal is to use ROS with a PixHawk for drone flights. Any help would be greatly appreciated. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
