EMAC fragmented Packet SOP ERROR

Shino Samuel
Intellectual 960 points

Hi 

I need to implement this fragmented Ethernet frame structure in my project (with customized fragment size). But when i give the descriptor as in fragment 1 (SOP,OWNER) & fragment packet (OWNER) &End of fragment (EOP,OWNER)  MACSTATUS is showing SOP error and TX0PEND is not showing HIGH.  How can i solve this issue to send a fragment frame in EMAC.  Single fragment frames are transmitting correctly with the descriptor i initialized. I didn't find any examples from TI on fragmented memory transmission in BSL or NDK's. 

I also have doubts like;

1. whether the linked list should be initialized before transmitting the frames?

2. As in the pic, is there any need to send a non fragmented frames before and after fragmented frames?

I request someones help to solve this issue. Kindly use this post also
