<br>
I want to run an UART communication between the mt7688 and another<br>
board, console uses UART0 but I want to configure UART1 to be able to<br>
send data on it. Currently, if I send something on /dev/ttyS1, I get:<br>
write to fd 4 failed: I/O error<br>
or<br>
ash: write error: I/O error<br>
<br>
root@OpenWrt:/# stty -F /dev/ttyS1<br>
stty: /dev/ttyS1: I/O error<br>
<br>
Should I add something in the dts?<br>
<br>
Thanks<br>
