Title: Don't get a connection via UART
Post by: dualsbiker on May 04, 2016, 01:32:05 pm
Hey there,

I'm using the iMX233-OLinuXino-NANO and prepared a SD-card with Debain. Using the U-Debug connector works, I can see the (I guess it's a kind auf dmesg output) booting output. I can't type any commands. Using the DUART on CON2 has the same result. I never see the common Linux Login. Does anybody has an advice for me ? I don't know what I have to do, to get the serial communication running.

Does it get to a prompt or login prompt?

Which exact image did you use?

And what h/w are you using to connect with?

IIRC there is some confusion between different kernels and rootfs how the
device file for the debug console is called, which can cause init to not
be able to start a login prompt.

Maybe you can add "ls /dev/" to /etc/rc.local and compare the output
with /etc/inittab
