Hi all


I'm developing product with i.MX7D.


Please tell me how to judge the reception completion status when receiving data from the LCD module with eLCDIF


After setting the receive register and writing the RUN bit, I watched the interrupt status, but the VSYNC_EDGE interrupt and the CURE_FRAME_DONE interrupt bit did not change.


Even if the interrupt bit does not change, the receive data buffer was storing the expected receive data.


After judging the reception completion status, I'm thinking to read the received data from the LCDIFx_DATA register.

Then I use the data in my application.


So please tell me how to know the status of finish the receiving data from LCD module.
