Hello,

Could you please provide the following details?

1. Which SDK version are you using?

2. Which sample code are you running?

3. Are you running on the EVM or PC emulation mode?

4. Have you run the script "./psdk_rtos/scripts/setup_psdk_rtos.sh"?

Regards,

Lucas

Hello,

The TIOVX version you linked to is an older version of TIOVX intended for support on TDA2/TDA3 SoC's. If you are intending to run TIOVX on TDA4, I would recommend downloading TIOVX as a part of the below SDK, as it includes the dependencies as well as scripts to download external tools needed to run the SDK.

Additionally, the PyTIOVX tool is only supported for kernel generation. The use case development feature is experimental and is thus unsupported in our SDK. For developing applications using OpenVX, we recommend referencing the vision_apps project included within the SDK linked to above.

Regards,

Lucas
