Shell window on the touchscreen of am335x with usb keyboard (Sitara Linux)

Hello,

I wonder if there is an easy way to open a shell window on the touchscreen of am335x which I can control using an usb keyboard. We use Sitara Linux. I tried to connect a keyboard and to use the Linux shortcuts (ctrl alt Fn) with no effect, I also removed some splash-screen stuff from /etc/init.d but that also gave no success.

(In the Lab I use SSH, but for a customer demonstration of an early GUIless prototypeI want to show the device without any laptop or pc connected.)

Thank you,

Roelof Berg

    Here's how we solved this:

    We cut down the use-cases we wanted to show to the customer to eight scenarios. Then we added 8 buttons to MatrixAppLauncher (which was only a matter of an hour), removed the HTML-Description-Tag (to start the comsole app immediately) and linked 8 scripts to the 8 buttons that called out application with the command line parameters we wanted to show. Adding a nice icon was also possible within a few minutes. Looks really cool for a first presentation :)

    If someone else needs this:

    (I did this directly via SSH and vi on the targets persistent filesystem as this was a quick-hack for an early prototype only and we don't want to keep it in the release file system. In this case you can easily refresh matrix app launcer by klicking settings/Refresh Matrix to see immediate results.)

    to resurrect this thread:

    is there a documentation for booting linux into the login shell (or directly to root shell) for am335x starter kit? i've disabled matrix with 'mv /etc/rc5.d/S97matrix-gui-2.0 /etc/rc5.d/K97matrix-gui-2.0' and the system boots into an empty screen.

    the boot partition on the SD card has a uEnv.txt, to boot from tftp and mount root file system over nfs.

    how would one go about to make linux boot into the root shell window on the lcd, which can be interacted with a USB keyboard? setting console in uEnv.txt? updating /etc/inittab? reconfiguring kernel?

    thanks.
