Driver for OSD DISPLAYS OSD055T3020-32TS

Hello,

And i have flashed linux kernel version 4.9 (L4T 32.4.4) Ubuntu 18.04 , in my Jetson NX SOM module carrier board.

I am using OSD DISPLAYS OSD055T3020-32TS (4 lane DSI) , Please help me with the driver for it.

Thanks in advance.

But i want the driver for part number OSD055T3020-32TS

Jetson NX has no DSI lane supported.

Hello ,

We are Using High Speed Mezzanine to get DSI lanes.

Where does this “High Speed Mezzanine” connect to on jetson side?

SoM is connected to High Speed Mezzanine by DSI x2 Lanes / CSI 5 x 2 Lanes

Jetson Xavier series does not support DSI. Those pins only support camera.

Sir i am using Jetson Xavior NX and Nano SoM.And their we have DSI signal and connected HIGH SPEED MEZZANINE EXPANSION CONNECTOR (HS) 5177983-2

Yes, only Nano supports DSI.

NX is Xavier series SoC. which does not support DSI. You can refer to the NX module data sheet for this information.

Yes sir ,

I agree that only Nano supports DSI.

But i want the driver for part number OSD055T3020-32TS. Please help me with the driver

That is the vendor driver. Please contact the vendor for help.

Kernel source may include upstream kernel. And those drivers are not released by us.

But sir , we already have driver of osddisplays,osd057T0559-34ts, but i have different part number as OSD055T3020-32TS .

Let me try to explain this more clearly. Looks like you don’t quite understand how things work. You are just in a loop and ask same things again and again.

  1. Only Jetons TX1 and TX2 series are able to support DSI. It means there is a dedicated DSI controller on these modules.
    However, Jetson xavier series does not have this controller. So no software change can enable this. Even you have a panel driver, it cannot run over our DSI lane.

  2. We don’t produce panel. So panel driver and datasheet should be from the panel vendor but not us.

okay sir ,

Thanks for making things clear.

Hello @WayneWWW Sir,

My target is to test DSI lanes present in Nano , We planned to do it by X2 DSI display.

But i could not find any X2 DSI display compatible with our NANO to test the DSI lanes. Please help.
