In my (limited) testing I saw no issues that the camera would not come up. It takes 2 to 3 seconds until the pipeline is running but I noted no hickups. I did this with setting the resolution to 640x480 and 1920x1080 which probably would not relate to the LP-11 issue you mention. I.e. I set up the v4l2 pipeline and start capture to the screen as follows:Just curious: which baseboard did you use to test the ov5640 camera? Most likely there was an issue with the customer's baseboard that prevented the camera capture to start.
I used an 'Apalis Evaluation Board' with an 'Apalis iMX6 Mezannine V2.0A'. Now I did retry and it works equally well on an 'Ixora V1.1A' Note that in the beginning the camera module required the SoM to provide a 24MHz clock. The V1.1B HW version then got its local oscillator and the clock input no longer requires a clock. That may or may not have been the issue your customer saw.
