PROCESSOR-SDK-J721E: PROCESSOR-SDK-J721E

Part Number: PROCESSOR-SDK-J721E

Thank you for viewing. I am using the TDA4 of the J721E board and I cannot find the GPU APIs. The TI supplier let me to see the demo under the folder vision_apps\apps\basic_demos\app_linux_arm_opengl_mosaic, but I still didn't find GPU APIs. I want to ask:

1. Where is the GPU interface?

2.Is there any other information besides TRM? Which part should I watch?

3.Is the GPU controlled directly by A72 under Linux, or controlled by other main domain CPUs?

    Hello,

    1. You can look at /ti/j7/workarea/vision_apps/kernels/sample/a72/gpu_render_1x1.c

    2. The GPU uses the standard OpenGLES interface

    3. Yes, the GPU is controlled by A72 linux using OpenGLES libraries and vendor proprietary user mode and kernel mode driver. 

    Hope this helps.

    Regards
