Hello,
I cannot find anywhere how can I setup more UART (there should be 6 of them), I have only one (the debug connector). In A20 I just setup script.fex and everything was fine, but how can I setup uarts in A64?
Thank you for any answer!
In mainline kernel you use overlays instead of script.bin/fex. We haven't published such for A64 boards but we have published overlays for the A20 boards. These two links should be used as the starting point:
https://docs.armbian.com/Hardware_Allwinner_overlays/
https://github.com/armbian/sunxi-DT-overlays/tree/master/sun50i-a64
Then check our work for the A20 boards:
https://github.com/OLIMEX/OLIMEX-sunxi-overlays
Thank you, that is exactly what I needed.
