Finding the solution to install ROS and get UART working

[jjj44 0]

I am currently attempting to use a TinkerBoard2S as a rosbag recorder for various sensors,
and I am encountering a few issues.

Here are my requirements:

1. I need to install ROS on the TinkerBoard2S.
2. I need to be able to read UART for IMU data.

Initially, I attempted to install the complete ROS system via a simple deb installation, but I ran into issues because ROS does not support Debian10 well. I then tried to follow the instructions on this page (https://github.com/lawkee48/TinkerOS-ROS), which allowed me to run roscore, but I encountered a problem when trying to compile the PCL library for my Velodyne sensor, as it took too long.

Next, I tried installing Ubuntu20 on the TinkerBoard2S, which made it easy to install the full ROS system. However, I am now unsure how to enable the UART port on the Ubuntu20 system. I know that for the TinkerBoard2S, I only need to set /boot/config.txt and set the intf:uart0=on. After rebooting, the ttyS0 should be mounted as the UART port.

Any suggestions on how to proceed would be greatly appreciated. Thank you!
