TSE lost packets - What can I do?

Hello, 

 

I built a design in which TSE is feed by a SGDMA which is connected to DDR2-RAM. 

For each packet is send by TSE a descriptor for SGDMA exists. Everything works correctly until sending the first 340 packets. Then some packets get lost. 

 

I tried stopping SGDMA after 339 packets for a very short time and then let it continue. Then it works until the next 340 packets are transferred. And so on, and so on... 

 

What could be the problem? I would like to use the design without stopping SGDMA... 

 

Best regards!
