I try to get UART running on NanoPi Neo but I miss the uart /dev/ devices.
What is the correct way to activate the UART? I am using the UART1 (CON1, Pin8,Pin10)
The image I use is: nanopi-neo_ubuntu-core-xenial_4.11.0_20170519.img

The document that was in the package reads: nanopi-neo-core-qte-sd4g.img . However, I cannot find it.

Thanks for any help
