UEXT ttyS0 problem

[blackwhite]

Hi everyone,

I have got a RK3188 evaluation board kit. I need to use both of the UEXTs as RS232. I was able to use the UEXT2  (which is ttyS3) but UEXT1 (ttys0) is not working properly. Is anyone knows what might be reason for that and possible solutions?

Here what is written on inittab file, I guess ttyFIQ0 is not same as ttyS0 and I did not comment it from the file.

0:2345:respawn:/sbin/getty -L ttyFIQ0 -a root 115200 vt100

Have got a solution for that by myself.

When I connect the board to PC using uart debug it conflict with ttyS0 as well. If I connect it through SSH it works well.

It also works if you also comment the line below from the inittab make sure that you have got an SSH on the board.

0:2345:respawn:/sbin/getty -L ttyFIQ0 -a root 115200 vt100
