Hi, 

i have a problem with HDMI display rotation on iMX6. I'm using a Congatec Module that mount a iMX6 Solo.

I have a TFT Monitor 7' with resolution 800x480.

With a init script i define the resolution at startup:

 

xrandr --newmode "800x480_60.00" 60 800 824 896 992 486 483 493 500

xrandr --addmode DISP3\ BG\ -\ DI1 800x480_60.00

xrandr --output DISP3\ BG\ -\ DI1 --mode 800x480_60.00

 

and the display view and resolution is ok:

 

but when i send command "xrandr -o left" the display rotated with error, because the top bar goes in the bottom and crop the screen:

 

 

There are similar problem when the rotation is "right" but display shifted down.

 

Anyone have an advice to fix the problem?

 

Thanks,

Marco
