uart1

Hello.

How use uart1 ?

I want use MCU wiht UART interface on NanoPI NEO.

I use overlay:

/dts-v1/;
/plugin/;

/ {
	compatible = "allwinner,sun8i-h3";
};

&uart1 {
	status = "okay";
};


# dmesg -a | grep uart
uart0: <16750 or compatible> mem 0x1c28000-0x1c283ff irq 35 on simplebus0
uart0: console (115384,n,8,1)
uart1: <16750 or compatible> mem 0x1c28400-0x1c287ff irq 36 on simplebus0

FreeBSD 12.2-STABLE


For test I connect two NanoPI NEO by help RX-TX.

On first boart I run
cu -l /dev/ttyu1

On second boart I run
cu -l /dev/cuau1

But I cannot write on first and on second board.

Please tell me where is my mistake.

Regards.
