PROCESSOR-SDK-DRA8X-TDA4X: AR0233 in built ISP Capture display usecase issue

Part Number: PROCESSOR-SDK-DRA8X-TDA4X

Hi,

I am trying to develop an application with camera and display node as i am using AR0233 in built ISP sensor.

I referred test_capture_display.c and modified single camera app by just keeping capture and display node. I also modified SerDes registers in imaging part.

I modified setting data format to FVID2_DF_YUV422I_UYVY in tiovx\kernels_j7\hwa\capture\vx_capture_target.c and VX_DF_IMAGE_UYVY in single camera app but not getting frames and application keeps waiting at vxGraphParameterDequeueDoneRef() only.

Please guide me to resolve issue.

Regards,

Prashant

    Hi Prashant,

    Please refer to FAQ . This explains how to change multi-cam example for YUV sensor. In addition to these changes, you might require changes to configure ISP.

    Hi Brijesh,

    Thank you for response.

    I have tried that patch for YUV422 input to TDA4X but getting below error during capture graph creation.

    Hi Prashant,

    It seems it is giving error while adding some graph parameter. can you please add some debug info and try to figure out for which parameter it is giving error? 

    Rgds,

    Hi Brijesh,

    I resolved that issue. Actually there is correction in patch as need to use captureObj->image_arr[q] = vxCreateObjectArray(context, (vx_reference)image, , sensorObj->num_cameras_enabled); instead of  captureObj->image_arr[q] = vxCreateObjectArray(context, (vx_reference)raw_image, , sensorObj->num_cameras_enabled); for yuv capture enable.

    Regards,
