    Hello Yordan/Anuj,
    I was able to resolve the issue.I added code for setting capture parameters for CHAINS_CAPTURE_SRC_OV490 in chains_common.c under vision_sdk/apps/src/hlos/common.I am able to do object detection and my use case detects pedestrian,vehicle and traffic signs in hlos.
    But the object detection stops after sometime with the following error messages displayed continuously in the terminal:

    SYSTEM: IPC:[DSP1] Notify recvfrom failed <Link has been severed,67> !!!
    SYSTEM: IPC:[DSP1] Notify recvfrom failed <Link has been severed,67> !!!
    SYSTEM: IPC:[DSP1] Notify recvfrom failed <Link has been severed,67> !!!
    SYSTEM: IPC:[DSP1] Notify recvfrom failed <Link has been severed,67> !!!

    I request you to resolve this issue.

    Best Regards,

    Hi,

    After how long you observed this issue?
    Have you made any changes in any link or the usecase ported from RTOS.
    Even after getting this log whats the effect on running the usecase?

    I will suggest to please recheck your changes and try a clean build.
    Regards,
    Anuj

    Hello Anuj,
    The duration was random.When the error occured the display turned green.But during my last data collection activity(I modified the chain for storage of video to a file) there was no error.We can close this thread for now.I hope I don't get this error again.

    Best Regards,
    Vijay
