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.
