    Hi, all!!
    I'm trying to make a minimal filesystem to use on Udoo.
    My idea is to be able to show things (Image,text) on the display (HDMI/LVDS) without using X11 only the FrameBuffer.
    I can draw in the FB but I would like to be able to apply rotation of 90º, 180º, 270º.
    I try to change the rotation value of FB /sys/class/graphics/fb0/rotate but I can only put 0 or 1
    0 - Normal rotation
    1 - Mirror rotation
    I have enable CONFIG_FRAMEBUFFER_CONSOLE_ROTATION in the kernel.
    Is there any way I can rotate the framebuffer by 90/180/270 degrees?

    - Kernel 3.14.56 (Oficial)
