My program is able to send and receive Ethernet frames using TCP protocol. The socket is created and for every 128ms I am sending 15 frames. For each frame, number of databytes is 17 (0x11).
My card is Client and PC is Server.
While I run the code, the first few (around 4 or 5) frames are sent and received at PC side. I am seeing them on Wireshark. The PC is sending acknowledgment frame too. After 4 or 5 frames were sent, the MCU (my program) is not able to receive the acknowledgement even though PC is responding with proper acknowledgment. So, MCU is re-transmitting the same frame with a limit of 4 times. For every re-transmission, the PC is responding with acknowledgement.
I have tried by including 20msec delay after the frame is sent by MCU. Then around 10 times the data frames were received at PC properly with acknowledgment. But later, the same issue as in previous.
My socket connection close time is 10sec. After re-transmitting 4 times, no frame is transmitted until certain time. Within that time, my socket is closed and new socket is created. Then again the same thing repeated.
The Hardware is all correct. I'm using S32DS Power arch. V2.1, MPC5777C controller FEC peripheral, DP83848i PHY module.
I have attached the wireshark data.
Requesting to provide solution for this.
