Hi, I am working with PSOC6 and W610io Ethernet controller. I write TCP-Echo server. the socket is initialized and starts to listen, but the socket is not established. SPI protocol gives a chip version Register. Are there any problems in the code? I write the same code for STM32F746 it works but with PSOC6 it does not work. #define LISTEN_PORT 5000 #define RECEIVE_BUFF_SIZE 1024 uint8_t receive_buff[RECEIVE_BUFF_SIZE]; wizchip_setnetinfo(&gWIZNETINFO); printf("VERSION(%x) = %.2x \r\n", _VER_, getVER()); print_network_information(); wiz_PhyConf phyconf; phyconf.duplex=PHY_DUPLEX_FULL; phyconf.speed=PHY_SPEED_100;//100MBps Ethernet link speed phyconf.mode=PHY_MODE_AUTONEGO;//best to go with auto-negotiation ctlwizchip(CW_SET_PHYCONF, (void*) &phyconf);//PHY Configuration Command*/ //*** End Phy Configuration printf("\r\n*****************SIMPLE TCP ECHO SERVER******************\r\n"); PrintPHYConf(); while(1) { printf("\r\nInitializing server socket\r\n"); if(socket(1,Sn_MR_TCP4,LISTEN_PORT,0)!=1) { printf("Cannot create Socket!\r\n"); while(1);//halt here } uint8_t socket_io_mode=SOCK_IO_BLOCK; ctlsocket(1, CS_SET_IOMODE , &socket_io_mode);//set blocking IO mode uint8_t lis = listen(1); printf("Start listening on port %d ! \r\n",lis); //Make it a passive socket (i.e. listen for connection) if(lis!=SOCK_OK)//our socket id is 1 (w5500 have 8 sockets from 0-7) { printf("Cannot listen on port %d",LISTEN_PORT); while(1); } uint8_t sr=0x00;//socket status register do{ Cy_SysLib_Delay(100); sr=getSn_SR(1); printf("Start listening on port %x ! \r\n",sr); }while (sr!= SOCK_ESTABLISHED); if(sr==0x00) { printf("Some error occurred on server socket. Please restart.\r\n"); while(1); } if(sr==0x17) { printf("A client connected!\r\n"); printf("Waiting for Client Data ...!\r\n"); while(1) { int len=recv(1, receive_buff, RECEIVE_BUFF_SIZE); if(len==SOCKERR_SOCKSTATUS) { //client has disconnected printf("Client has disconnected\r\n"); printf("*** SESSION OVER ***\r\n\r\n"); // break; } receive_buff[len]=''\0''; printf("Received %d bytes from client\r\n",len); printf("Data Received: %s", receive_buff); //Echo the data back encloused in a [] pair send(1,(uint8_t*)"[",1);//starting sq bracket send(1,receive_buff,len);// the data send(1,(uint8_t*)"]",1);//closing sq bracket printf("\r\nECHO sent back to client\r\n"); //Look for quit message and quit if received if(strcmp((char*)receive_buff,"QUIT")==0) { printf("Received QUIT command from client\r\n"); printf("Disconnecting ... \r\n"); printf("*** SESSION OVER ***\r\n\r\n"); disconnect(1);//disconnect from the clinet break;//come out of while loop } } }//if block, client connect success }//while loop }
