Hello,

We have enabled the network_rx_tx app to work with the network_rx tool in the SDK. But we are getting the following error when we run it. What is going wrong?

[IPU1-0]    569.371378 s: Chains: Using TFDTP. Ensure using ��–-usetfdtp with network tools..

    Hi Siddarth,

    Which camera have you connected to the vision app board.
    You need to connect OV10635 and also set the video capture pins accordingly

    Hi Chetan,

    The network_rx_tx app uses video capture drivers from "vision_sdk/apps/src/rtos/video_sensor/src" which has the OV10635 driver.

    The iss_capture_isp_simcop_display app uses capture drivers from " vision_sdk/apps/src/rtos/iss/src/sensor" which has the OV10640 driver.

    We want to use the network_rx_tx app with the OV10640 camera. How do we make this possible?

    Hi Siddarth ,

    before running the usecase select the camera source .

    from main menu run 'S' the capture source .
    Depending on the capture source connected select the capture source.

    you can verify the same by printing the pObj->chainsCfg->captureSrc which is passed to ChainsCommon_StartCaptureDevice

    Regards

    Yes we did all that. But the OV10640 camera is not supported in the network_rx_tx app. If you select it then it just fails at an assert statement. See log below. The prints we have added are with ATI.

    Please re-verify the capture and sensor configurations

    We added the TFDTP support for the /iss_capture_isp_simcop_display application. This enabled us to transmit the frames captured from the OV10640 camera to the network. On the receiving side we used the network_rx application. This has resolved our issue. Thanks for your help.
