I’m having trouble getting UART enabled. I’ve gone through many different directions on how to enable and troubleshoot from updating the uEnv.txt file to updating the kernel.
I’ve come to conclude that it may be an issue with using a different kernel than the instructions, but I’m not sure?
I don’t know very much about the Beaglebone and I’m still learning.
Whenever I try to test UART by using Python and typing the following:
import Adafruit_BBIO.UART as UART
UART.setup(“UART1″)
I get the error:
File “stdin”, line 1, in module
RuntimeError: Unable to export UART channel.
I’m also starting to worry that I simply don’t have capemgr. When I run the command :
ls sys/devices
I don’t have capemgr listed.
I’m using the latest Debian Image : Jessie Debian 8.3 (2016-01-24)
the Kernel version I’m running is 4.1.17-ti-rt-r46.
and my DTC version is 1.4.1-g1e75ebc9
I would really appreciate any help. I’ve been wrestling with this issue for a few days now. Thank you!
