How to make a tcp packet by our own using Ostinato software

Question

Hello , I am working on Wiznet 812MJ module (having W5100 chip) . I am trying to send a packet using Ostinato to my embedded board having this module connected with it through SPI . In my case Ostinato shows packet send but on my side i am not getting any packet . Even the Flow graph doesn’t show 3 way hand shaking signals it only shows RST signal . After looking for the solution for quite a while i got to know that this s/w doesn’t synchronise , it only sends the packet , Is this correct ?? In one case : I tried to send the TCP packets from PC1 to PC2 , my packets got correctly transmitted and received the correct data , then i could not understand why not with my board ? waiting for reply Thanks

If you got the RST packet from your board, first check your board is listening correctly. For the network debugging, I recommend to use the Wireshark ([url]http://www.wireshark.org/[/url])
