is it possible to remap Pixels using an Z37xx with Mipi-DSI x2 Display

Hi Community, nice to be here!

Well really have to challenge a big target (I think so), where I have an Bay Trail z37xx which drives an Mipi-DSi panel, that has an resolution of 800x1280, yes it is an vertical design.

The biggest difference of the vertical display is the position of pixel [1,1], it differs to default 1280x800 display exactly 90° counter clockwise, that means, that for example the AMI Bios will be also displayed 90° rotated and stretched in height and squeezed in width.

but now the project concept changed, and content needs to be consistently displayed in landscape, that means I only need to remap the pixels:

Left upper corner of an image, => Picture pixel [1,1] --> physical pixel [1,800]

right upper corner of an image, => Picture pixel [1,800] --> physical pixel [1280,800]

right lower corner of an image, => Picture pixel [1280,1] --> physical pixel [1,800]

Left lower corner of an image, => Picture pixel [1,1] --> physical pixel [1,1]

with SPI Displays it was no issue to use the framebuffer for a rotation of the picture, and the z37xx vol2 manual shows a lot of settings, but it seems they are only able to handle 0° and 180° "rotation"

I knew this is really no easy challenge, and my knowledge seems to be too limited here...

So a helpful tip would be very appreciated...

Thanks in Advance from Germany, Thorsten

Hello ThorstenK

-Are you performing this changes on BIOS level?

-What operating system are you using?

-What is the doc # of the manual that you are using?

Best Regards,

Adolfo

Hello AdolfoS,

thanks for your reply!

Doc Id I refered is 329474-003

It will be a Windows Core 10 System, which makes it more restricted... In an Android, or Linux kernel I would know how to use framebuffer to makes i stable rotated into the desired direction.

And this is the reason, why only a Bios/Bootcode based solution maybe stable enough to fix that behavior....

Unfortunately the l Z37xx Bay Trail -T is on the "off-roadmap" and its support is for limited manufacturers. For this reason, we do not have support for this processor.
