Use of IPU to rotate LCD display on i.MX6

[DipenPatel1z]

Dear All,

We need to rotate LCD display by 180 (due to hardware/mechanical design placement). Since it is going to be a permanent I can't use any application logic to burden the CPU. So I need to use IPU for 180 rotation of frame buffer before it is displayed on LCD. However I am not sure if this can be achievable and if yes then how?

Let me know if any one has gone through such scenario and has working solution. Appreciate any help.

Regards,

HI Igor,

Thanks for the reference. We did exactly as described in "i.MX6 IPU and rotating a frame buffer" but only Linux boot logo is rotated. When our Qt application starts all GUI appears NORMAL without rotation. Not sure what is wrong with our driver changes.

Appreciate any help on this.

Hi Dipen,

Were you able to rotate all the GUI with QT/Weston ? I have the same requirement due to our display placement and need to rotate by 180 degree?

It would be very helpful if you could provide some help here?

Hi Dipen

If you are using Android than you can use Android rotation property , it will solve your problem
