Serial communication problem in BeaglePlay Board

Dear Support,

I hope this message finds you well. I am currently facing an issue while attempting to establish serial communication on my BeaglePlay board. The specific error message I am encountering is as follows:

Traceback (most recent call last):
File “/home/debian/”, line 7, in
RuntimeError: Unable to export UART channel.

It seems that the code is unable to export the UART channel properly, resulting in the mentioned runtime error. To provide further context, I have also included the code I am using:

import Adafruit_BBIO.UART as UART

I would greatly appreciate any assistance or guidance you can offer to help resolve this issue. Thank you in advance for your support.
