TDA4VM: Tiovx Related Issues

Part Number: TDA4VM

Hi~

Recently I am optimizing the vision application which are base on tiovx, there are two questions I don't figure out:

1. Is it feasible that two processes on A72 call tiovxHostInit() and create graph? But these two processes use different nodes such as capture node, viss node, ldc node. Are there any precautions that I need to pay extra attention to?

2. Generally speaking, the code of imaging including I2C configuration of csi cameras and the code of viss are run on MCU2_1, can I port these code to MCU2_0? Is there any guidance documents?

Hi Billy,

We will get back to you on this by Monday.

Hi Billy,

On #1, yes this is possible. We have a demo testing this by running one OpenVX process that runs a surround view demo with another process running a valet parking application which runs tivxHostInit within both processes.

On #2, could you specify the nodes which you are trying to use on the MCU2_0 rather than MCU2_1? This is possible but I can provide some specific guidance on how to do so if you provide the nodes. We do not have guidance document for this specifically, but the below thread provides the general steps needed to do so.
