SK-AM62: LVDS(OLDI) interface instead of HDMI(DSS)

Hello Magnus

Thank you for the query.

Is there a block diagram explaining your requirement?

Let me check internally on this and update you.

Hello,

What I want to do is to use the LVDS interface(on the backside) instead of the HDMI.

When I run the "Processor SDK Linux for AM62x 08.03.00.19" it shows graphics on the display connected to HDMI port. I want to show the graphics on display connected to the LVDS port instead.

I don’t have a block diagram.

Hello Magnus

Thank you for the input.

Ok, looks like you do not have any queries related to the hardware but looking to use the OLDI in the below linux version:

I am using AM62-SK Rev E2 with “Processor SDK Linux for AM62x 08.03.00.19”

Please help me understand if my understanding is correct for me to internally assign to thread to the expert.

I cant find any instructions how to do that.

Hello Magnus,

We are still working on the upstreaming the patches. In the above link, you could find the patches for enabling LVDS in software.

Hello,

I guess this will be implemented in the next release of "Processor SDK Linux for AM62x". Correct?

When is that release planed?
