Videostream packets

Hi there, I have a simple question for you all (I think:)) At this point I have a simple HDL design for Cyclone III Video Kit. Getting a PAL input on the clocked video input -> some clippi...

It's been a while and I made some progress.

1. The code for chopping the videostream into packets works when I'm simulating it in ModelSim and the videopackets are small enough to fit in a UDP packet.

2. I've added a UDP payload inserter and padding from this project: http://www.nioswiki.com/exampledesigns/nios2udpoffloadexample

3. Written SW code to initialize and start up the UDP payload inserter.

Now here is the problem ... the TSE component won't send out any packets made in HW. The simple socket example works fine in my design (which is sending packets in SW).

Any suggestion of what can be wrong?

Here's the flow through the different components:

packet chopper -> udp payload inserter -> padding -> mux with packets from SGDMA component (TS Multiplexer) -> TSE MAC.

Can the TSE MAC discard packets instead of sending them out?
