Hello Cherry,

We are looking into this right now. For clarification, this is using version 7.1 of PSDK RTOS?

Yes.

The customer would like to know if it's possible to provide the technical manual of TDA4VM OpenGL to confirm the coordinate system of OpenGL under TDA4VM.

Thanks and regards,

Hello Cherry,

We do not have a technical manual of OpenGL specific to TDA4VM. OpenGL is just a standard that we follow and should be the same on PC or TDA4VM. 

Also, using PSDK Linux and running a pure OpenGL application, I do not see the image flipped so I do not think it is an issue with the implementation of OpenGL for TDA4VM. Since the customer is using PSDK RTOS, this could be an issue with the OpenVX GPU node. I will need a few more days to debug this. 

Lastly, has the customer changed coordinate system in their application?

Hello Cherry,

As a follow up question, are the customer using the display node on R5 to display the image?

Hello Cherry,

How is the image being dumped? Is this following the flow in our demo: https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/08_01_00_13/exports/docs/vision_apps/docs/user_guide/group_apps_basic_demos_app_arm_mosaic.html
