[OpenWrt-Devel] UART1 mt7688

[Baptiste Clenet]

Hi,

I want to run an UART communication between the mt7688 and another
board, console uses UART0 but I want to configure UART1 to be able to
send data on it. Currently, if I send something on /dev/ttyS1, I get:
write to fd 4 failed: I/O error
or
ash: write error: I/O error

root at OpenWrt:/# stty -F /dev/ttyS1
stty: /dev/ttyS1: I/O error

Should I add something in the dts?

Thanks
