       Camera init time can be reduced by enabling broadcast.  It can be enabled as follows

      1. Go to the file imaging/sensor_drv/src/imx390/iss_sensor_imx390.c
      2. Look for “imx390SensorIntfPrms”. It has a field sensorBroadcast which is 0 by default. Set it to 1.
      3. make imaging_scrub.
      4. Build SDK and flash SD Card.

      In PSDK QNX 7.3 SDK, when testing this feature, sometimes cameras are visible on display, other times cameras are not visible.

      In past J6 experience, issues like this were could be addressed by adjusting delay values on certain I2C commands, not clear if this is the case here.

      A full boot, plus running of application and "print" of stats, for the failing case on QNX is attached.

      Would put reproducibility at 50% but only tested ~5 times.
