How to install SPI and UART on Jetson TX2

New to the Jetson in general, but wanting to install/enable SPI and UART on the TX2.
Already installed Ubuntu, ROS, and the latest drivers.
Any information to install/ enable will help!

Thank you!

Please check below wiki

There is one difference between a TX1 and TX2 serial console/UART which might be important: The TX2 flow control does not work, so you cannot set CTS/RTS (hardware) flow control (having those wires connected won’t hurt anything, but having CTS/RTS set will prevent your keyboard from sending to the TX2).

If you are interested in a different UART (e.g., J17/ttyTHS2), then you might add more details to your question.
