Ive just tried Ubuntu , and no luck
we need it to work on ubuntu
I had changed device tree files (.dtsi) in different ways and again no luck

yes I had disabled it in rk3128-fireprime.dts file
and enabled uart0 node
For now i've given up fireprime evb as i dont have enough time to work on it
besides it has just one uart available while i need at least 2 uart ports
I think I would work with RK3288-Reload
Thanks for your support bro
