TDA4VM: UDMA to Transfer Video Frames Between Applications on TDA4VM

Kishore Mali

Part Number: TDA4VM

Tool/software:

Hello Team,

We are working on TDA4VM based board and currently using shared memory to transfer video frames between two applications (App1 to App2). We'd like to explore the possibility of using UDMA instead of relying on the CPU or shared memory logic for this inter-app communication.

Questions:

  1. Is it possible to transfer video frames from one application (App1) to another (App2) using UDMA on the TDA4VM platform?

  2. If yes, could you please point us to any example code or references in the SDKs that demonstrate UDMA usage for memory-to-memory transfers or similar use cases?

SDK versions used:

  • Linux: ti-processor-sdk-linux-j7-evm-08_01_00_07-Linux

  • RTOS: ti-processor-sdk-rtos-j721e-evm-08_01_00_13

Any guidance or suggestions would be greatly appreciated.

Thank you!
