Usually u-boot is used, so:

1. interrupt u-boot and change the command line
try help to see what you can do or read up on uboot
things like printenv are useful
(then saveenv / env save may work)
2. or if you want it to be the default, edit the commands (on the SD partition) that u-boot will be using

Hi Jhohns,

maybe I wasn't clear, but I need start linux in command mode( or text mode).
Usually the system starts in graphical mode, lxde to be precise. Then I can press ctrl+alt+f1 to change to command mode.
I'm not sure if uboot is used to do it. Well I couldn't find where it is done.
With x86 linux We can set inittab to do it, but with OlinuxIno I haven't this option.

You could try what I posted.  (In any case you have inittab or its equivalent.  It's just Linux)

I turned off the lightdm with the command
chmode -x /usr/sbin/lightdm

The system will start in text/command mode.
