Hi Maxime, I'm using a ST board with OV5640 wired in parallel bus output in order to interface to my STM32 DCMI parallel interface. Perhaps could you describe your setup so I could help on understanding the problem on your side. From my past experience with this sensor module, you can first check hsync/vsync polarities, the datasheet is buggy on VSYNC polarity as documented in patch 4/5. Best regards, Hugues.
