We have custom kernel for Beaglebone black with 7’inch LCD, it is configured as landscape mode. But for our application we want it in portrait mode.
We have tried these commands to rotate screen temporarily:
echo 1 > /sys/class/graphics/fb0/rotate
echo 1 > /sys/class/graphics/fb0/rotate_all
echo 1 > /sys/class/graphics/fbcon/rotate_all
We even tried to rotate the screen by using our Qt application, but result is same.
Please let us know, How we can rotate the screen by 90 degree during bootup?
