MIPI CSI-2 TX Subsystem - Why can the first Start-of-Frame (SoF) not be received by the MIPI CSI-2 RX in the simulation?

描述

When I connect the MIPI CSI-2 TX Subsystem to the MIPI CSI-2 RX Subsystem and send three video-data frames to the MIPI CSI-2 TX Subsystem using the native interface, the MIPI CSI-2 RX Subsystem can receive SOF for the second and third frame, but the first SOF is not there.

What can cause this problem?

解决方案

This issue occurs when the first SOF is sent before MIPI CSI-2 TX IP is ready. 
 
To resolve this you will need to follow the guideline of (PG260) Figure B-3 to send video data frames correctly using the native interface, and check the MIPI CSI-2 TX register Core Configuration Register to ensure that the MIPI CSI-2 TX IP is ready before sending out any video data.
