Orange Pi PC and OctoPrint

mforcen

First of all, hello everyone.
I had my OrangePi PC a long time ago, but right now I'm trying to use OctoPrint to manage and control my 3D printer.
The problem I have is that the serial port disconnects after a while. OctoPrint log says this:
Recv: T:200.00 /200 B:57.10 /65 B@:255 @:0
Recv: T:199.41 /200 B:57.14 /65 B@:255 @:230
Recv: T:199.41 /200 B:57.29 /65 B@:255 @:230
Unexpected error while reading serial port, please consult octoprint.log for details: SerialException: 'device reports readiness to read but returned no data (device disconnected or multiple access on port?)' @ comm.py:_readline:1532
Changing monitoring state from 'Operational' to 'Error: SerialException: 'device reports readiness to read but returned no data (device disconnected or multiple access on port?)' @ comm.py:_readline:1532'
Connection closed, closing down monitor.
Any ideas for solving that?
I think I could try to disable the UART port of the OrangePI, updating the kernel or something like that.
Thank you.
Greetings.
