        You've got a
            space in that... Between /dev and /dri. I don't think you
            want that.

    Sorry, thats a typo:

    [root@myodroid ~]# fbi -d /dev/dri/card0 -i

    using "DejaVu Sans Mono-16", pixelsize=16,67
    file=/usr/share/fonts/dejavu/DejaVuSansMono.ttf

    ioctl VT_GETSTATE: Inappropriate ioctl for device (not a linux
    console?)

            there,

            last step on my Odroid-Xu4 is console output on the small
            display at the Cloudshell (Cloudshell features a 2.2“ TFT
            LCD with a 320×240 resolution. The display is controlled by
            the well-known ILI9340 controller.)

            Is there any howto to get this display working with tinydrm?
            I didn't find anything beside https://github.com/notro/tinydrm/wiki/Tools
