Packets Sent to VIP Cores Must Have Non-Empty Payload

Description

The packets sent to the Color Space Converter and 2D Median Filter MegaCore functions must have non-empty payload. If a packet is sent with a type but without any further information, the packet processing logic may enter an inconsistent state.

This issue affects configurations that include the Color Space Converter or 2D Median Filter MegaCore functions.

If the IP core receives a packet with an empty payload, it may not output correct data until it receives a few non-empty packets.

Resolution

If you intend to send an empty packet, send one symbol of data with it.

This issue is unlikely to be fixed as there is a simple workaround.
