UART issue on the UP squared board

I'm trying to transmit data via UART on my UP board. I am using pins 8 and 10 for Tx and Rx. I connected my pin 8 to 10 and tried to send and receive data using pyserial. I wasn't getting any data back and it gets stuck in the loop after send command. "sudo cat /proc/tty/driver/serial" shows that both ttyS4 and ttyS5 are active but tried both and doesn't work.
I'm using Ubuntu 18.04 with kernel 5.4.0.1

We have verified the functionality to work with our kernel, please check the steps (if not already done) in our wiki: https://github.com/up-board/up-community/wiki/Ubuntu_18.04
Once done please install:
pip3 install pyserial
Then download and extract the script provided: https://we.tl/t-fUDtOSNIjq
Run it using python3 and you should see the serial communication to be working.
Hi @DCleri, I tried and I don't get anything on the receiver end (have connected pin8 to 10).
The serial communication doesn't seem to work. (FYI, I used the installation instructions from the link you mentioned above)
