hi,
I made a try on imX6Q Linux4.1.15 version,Rotate the screen 180 degrees. use command echo 1 > /sys/class/graphics/fb0/rotate .But the display is abnormal,Not only up and down, but also left and right.It's very confusing.So I tried to find the problem in the driver .I have found
drivers/video/fbdev/mxc/mxc_ipuv3_fb.c A corresponding parameter is passed 。I can't find the corresponding call ,but I can't find the corresponding calls and modifications that make it upside down, not left to right
Thank you for your help!
this couldn't be supported, you can use GPU2D to support rotation
hi,@joanxie
Is there any way to rotate 180 degrees? Is there any specific modification routine
Thank you for your help!
hi,@joanxie
What I want to do is display rotation of the screen, not play video rotation, do you have any other suggestions
