What worked for me with this error was to go to Tools -> Update Raspberry Pi, select Install, and from the popup screen, there are options to change your installation (I changed it to single core, instead of multicore), and I was then able to connect to my Rpi 4.

Hi, I try to send and receive data using a UDP connection via SysSocket 3.5.17.0. While sending data works fine, I have problems with the receiving part.I am able to capture the data of client side in wireshark but i am unable to capture it in the codesys. Heres the below part of code of client side. PROGRAM POU_udpclient_program VAR istep : INT := 1;//step variable for state machine xStart: BOOL;// Flag to start the UDP protocol iecSocketId: syssocket_interfaces.RTS_IEC_HANDLE;//socket handle for receiving iecCreateResult: syssocket_interfaces.RTS_IEC_RESULT; ipAddr: syssocket.SOCKADDRESS;//Socket address structure for receiving sIpAddress : STRING := '192.168.0.2'; wPort: WORD:= 12346; iecConnectResult : syssocket_interfaces.RTS_IEC_RESULT;//connect paramters sDataRec : STRING[255];//Buffer for received data xiRecBytes : __XINT;//number of bytes received iecRecResult : syssocket_interfaces.RTS_IEC_RESULT;//receive data parameters iecCloseResult : syssocket_interfaces.RTS_IEC_RESULT; END_VAR syssocket.SysSockInetAddr(sIpAddress,ADR(ipAddr.sin_addr)); ipAddr.sin_family := syssocket.SOCKET_AF_INET; ipAddr.sin_port := syssocket.SysSockHtons(wPort); CASE istep OF 1: //create socket IF xStart THEN iecSocketId:= syssocket.SysSockCreate(syssocket.SOCKET_AF_INET,syssocket.SOCKET_DGRAM,syssocket.SOCKET_IPPROTO_IP,ADR(iecCreateResult)); IF iecSocketId = syssocket_interfaces.RTS_INVALID_HANDLE THEN xStart := FALSE; istep := 1; ELSE istep := 2; END_IF END_IF 2: //connect to socket server using setoption iecConnectResult := syssocket.SysSockSetOption(iecSocketId,syssocket.SOCKET_SOL,syssocket.SOCKET_SO_REUSEADDR,ADR(ipAddr),SIZEOF(ipAddr)); istep := 3; 3: //receive data xiRecBytes := syssocket.SysSockRecvFrom(iecSocketId,ADR(sDataRec),SIZEOF(sDataRec),0,ADR(ipAddr),SIZEOF(ipAddr),ADR(iecRecResult)); istep := 4; 4: //close socket iecCloseResult:= syssocket.SysSockClose(iecSocketId); xStart := FALSE; istep := 1; END_CASE
