Hi team,
Here's an issue from the customer may need your help:
When the ISP NSF4 uses DCC for noise calibration, two intervals are divided by the gain values (XML file see attachment), using this calibration file will prevent the camera from illuminating (only one zone can be lit) and the following error is reported:
log：
J7EVM@QNX:/# [MCU2_0] CAM_PARAM_Handle_Fxn]:===+++++++++start_sending _camera_msg++++++====

Could you help look into this case? Thanks.
