how enable uart

Post by Nikkhah »

Hi
I run diet pi on orange pi win plus and now I need to use uart1, uart2 and uart3. I can't enable them in dietpi-config. how can I enable them? I see dtbo files in /boot/dtb directory and add them in armbianEnv.txt like this:
overlays= overlays= sun50i-h5-uart1 sun50i-h5-uart2 sun50i-h5-uart3
but they are not enabled! What can I do?
