About TCP client communication problems with SmartDSP OS

819277784 — Tue, 28 May 2019 06:13:41 GMT

I am already in the testing phase. When I tested the SGMII of MSC8157, my MSC8157 was doing a TCP client. The PC was a TCP server. The client could connect to the server and communicate easily. I encountered a very strange problem during the test. My specific operation is as follows:

After the client connects to the successful server, it will continue to send 1024 bytes of data to the server, but from the speed of receiving data from the server, there is only about 5-9KBytes per second (5 to 9K bytes/second). ), this feeling is very abnormal, the speed of the Gigabit network port should be at least a few megabytes, why is my only a few K bytes? Here is my configuration:

Hi：

I continue to find the problem today. During the simulation, I found that the reason why TcpSendBuff is slow to send is because TcpSendBuff returned an error when calling TcpSend. The place where the error occurred is as follows:

The return value of g_tcp_list[socket].acked is 0.So it will cause me to send out data and sometimes publish data.How can I solve this problem?

Sorry, it should be tcpBufferSend, not TcpSenBuff

Hi,

This is AE reply:

customer needs to debug how the g_tcp_list[socket].acked is used and allocated value to trace the root cause.
