2.5.3. Display Messages
The messages displayed when the simulation is run are designed to give helpful information about what the simulation is doing while it is running. The simulation transfers a large number of bytes using a large number of packets, it is not useful to provide information about all of these. Instead, messages are provided for significant events that represent the test set-up of 10 frames with a resolution of 128x96.
Some of these messages are dependent on whether the simulation is being run in video or passthrough mode.
- Sending and receiving of VVP Image Information Packets
- Receiving of VVP start of a new field of video
- Sending and receiving of VVP End-of-Field Packets
With the test set up for transmission of 10 frames, we expect to receive 10 VVP Image Information Packets, start of a new field of video and End-of-Field Packets.
In video mode, the first five image frames are consumed by the MIPI CSI-2 RX IP Core. This is done so that the RX IP Core can lock to the video resolution and ensure a stable video stream. The five frames are sent in addition to the 10 in the simulation.
- Receiving of a MIPI CSI-2 Frame Start (FS) Short Packet
- Receiving of a MIPI CSI-2 Frame End (FE) Short Packet
