5.3.1 Source Code Change

In the target file system on the EVM, go to /opt/edgeai-tiovx-modules/src/tiovx_sensor_module.c, and add the name of the sensor and id to the list in the tiovx_init_sensor() function. For example, IMX219 has the following:

// This line defines a new TIOVX camera sensor string ID for IMX219  
else if(strcmp(sensorObj->sensor_name, "SENSOR_SONY_IMX219_RPI") == 0) 
{  // This line assigns a new numeric DCC ID to IMX219 
   sensorObj->sensorParams.dccId=219; 
}

Both the sensor name and the DCC ID for the IMX219 camera are defined here. Use the exact name string – SENSOR_SONY_IMX219_RPI – in the GStreamer pipeline and the DCC sensor ID (219) is used by the tuning tool in future steps.
