Hi,

I have last version debian on BBB and cannot activate UART1 by explained in the examples.

Here is info of debian: Linux beaglebone 4.14.71-ti-r80 #1 SMP PREEMPT Fri Oct 5 23:50:11 UTC 2018 armv7l GNU/Linux

cannot find any info on dmesg and syslog about UART1 or ttyO1

If you have any idea, I appreciate that.

Here is /boot/uEnv.txt file
