This isn't the right way to fix the problem. Reading the EEPROM (and thus starting streaming) is a problem since the receiver has been already set up to receive a proper frame. EEPROM reading should be instead moved to pre_streamon callback. I suppose this way the sensor's CSI-2 TX is also set in LP-11 mode, as many CSI-2 receivers expect. -- Kind regards, Sakari Ailus
