Hi Noam,

I'm using the RAW API, I chose that for performance.

By sending random data I mean I allocate a buffer in the ARM core and continuously send that through Ethernet/UDP. I'm also trying to send the video through Ethernet/UDP, I'm basically sending the differences between consecutive frames.

Thanks for your time!

Best,
Gary

Hi,

 

What API are you using?... RAW, Netconn or Socket ?

 

When you say you send random data, how do you send it. I mean do you send it from

Within the LwIP context or via the route you try to send the video?

 

BR,

Noam.

Hello all,

I'm building a system which encodes video in a Zedboard FPGA and sends it out through the ethernet port. I have tested sending random data out and it works, but when I try to use the data from the video source I manage to set the ARM core/network in a locked state. I've also tested the system without sending any data through etherenet and it works fine.

I've increased memory and pool sizes; I also decreased the Time-To-Live for all protocols and tried using a global pbuf or a dynamic local pbuf.

These setting seem to get the system working a bit longer, but I still get locked whenever the video encoding requires to send more than random data.

Does anyone have suggestions on what I could do?

 

Best,

Gary
