I tried this too but not working. I rotated the console using
fbcon, but this has nothing to do with framebuffer rotation
I had a look at the sources of omapfb_main.c
if (fbdev->ctrl->set_rotate != NULL)
if((r = fbdev->ctrl->set_rotate(var->rotate)) < 0)
return r;
There is no set_rotate defined in dispc.c so the framebuffer is
not rotated at all, am i correct?
