We are using the OSPI port of STM32L4P to communicate with the DCMI port of STM32F427, and the problem is the end of data signal was sent, but there is no interrupt from the DCMI, while if we reset the OSPI of STM32L4P, the interrupt appears.

What is "end of data signal"? Do you have waveforms from logic analyzer? What are your connections?
