IMX8M display rotation

Hello,

I am using a iMX8M mini EVK + LVDS panel (with a SN65DSI83 bridge). The panel has a hactive of 1024 and vactive of 600

I see the following in the logs

01-01 00:00:15.032  3130  3130 W display : mode.width   = 1024 px

01-01 00:00:15.032  3130  3130 W display : mode.height  = 600 px

 

What I need to do is rotate the display so that the longer edge is the height and shorter edge is the width? Can I get some help to identify the changes needed in both Linux and if needed Android to make the system always display content with height 1024 and width 600?

 

I have tried using the steps here

https://devtalk.nvidia.com/default/topic/1029340/android-development/configure-display-orientation-to-reverse-landscape/ 

which shows no change.

I tried using fbcon:rotate=1 which did not work (Also saw later that the imx8m reference manual mentions fb is no longer used "Frame buffer drivers are supported for i.MX 6 and i.MX 7 but not for i.MX 8")

 

I have spent a week look at different combinations so any pointers would be very helpful.

 

Thanks!
