Tool/software:

Hi TI,

SDK8.6

Single camera demo:

Our camera does not have ISP, Output Data: RAW12

For the parameters in bold in IssSensor_CreateParams, how should we set them?

static IssSensor_CreateParams ar0233CreatePrms = {
/*IssSensor_Info*/
{
{
AR0233_OUT_WIDTH, /*width*/
AR0233_OUT_HEIGHT, /*height*/
1, /*num_exposures*/
vx_false_e, /*line_interleaved*/
{
{TIVX_RAW_IMAGE_16_BIT, 11}, /*dataFormat and MSB [0]*/
},
0, /*meta_height_before*/
0, /*meta_height_after*/
},
ISS_SENSOR_AR0233_FEATURES, /*features*/
ALGORITHMS_ISS_AEWB_MODE_AEWB, /*aewbMode*/
30, /*fps*/
4, /*numDataLanes*/
{1, 2, 3, 4}, /*dataLanesMap*/
{0, 0, 0, 0}, /*dataLanesPolarity*/
CSIRX_LANE_BAND_SPEED_1350_TO_1500_MBPS, /*csi_laneBandSpeed*/
},
1, /*numChan*/
233, /*dccId*/
};

Looking forward to your reply, thank you.

Hi Barry,

Did not get your question, you are already setting these parameters, isn't it? You are setting output format to be RAW12 and enabling AEWB algorithm..

Hi Brijesh,

Our purpose is only to get the original image of RAW12, without VISS and AEWB.

#1 Is there something wrong with the parameter settings here in image sensor?

#2 What settings need to be modified in the app_single_cam demo?

#3 Are there any other modifications required?

Looking forward to your reply. Thanks

Hi Barry,

In this case, you would need to modify the single camera application. I think in the current application, it bypasses VISS and AEWB for YUV sensor, so please check this code under YUV input format and you would need to update same for the RAW12 input format also.

Hi Brijesh,

Thank you for your support reply.

What do these errors mean? Is there something we missed in the settings?

Looking forward to your reply. Thanks.

Hi Barry,

There are a lot of Errors in received stream. there are CRC issues, ECC issues and also overflow errors. Are you sure that the number of lanes, lane polarity and lane speed are matching as per the output from sensor/deserializer?
