Why?
According to hardware architecture of OPI we have total 3 UART,but through current openwrt OS one port I can be able to access i.e /dev/ttyS0 (console port) but I want to enable any another port 1c28400.serial & apart from the console port (ttyS0) even I disable the console port again it is showing dmesg while booting i.e console [ttyS0] enable.
How?
