FreeRTOS Demo - Problem with Creating TCP Socket

[AshineChieShihSuhai (KürŞad CAKAL)]

Shortly, FreeRTOS IPInit() successful, but there is a problem as stated hierarchically below.

main.c :

FreeRTOS_socket( BaseType_t xDomain, BaseType_t xType, BaseType_t xProtocol )

FreeRTOS_Sockets.c :

->prvDetermineSocketSize( xDomain, xType, xProtocol, &uxSocketSize ) == pdFAIL
->->xIPIsNetworkTaskReady() == pdFAIL
->->->BaseType_t xIPIsNetworkTaskReady( void )
->->->{
->->-> return xIPTaskInitialised;
->->->}

xIPTaskInitialised is firing and setting pdTRUE in below

FreeRTOS_IP.c :
xReturn = xTaskCreate( prvIPTask, “IP-task”, ( uint16_t )ipconfigIP_TASK_STACK_SIZE_WORDS, NULL, ( UBaseType_t )ipconfigIP_TASK_PRIORITY, &xIPTaskHandle );

prvIPTask is created successfully and return pdTRUE but why socket creation is failing .

I check your answer before related topic below :

Lost in Sockets

You can look through this function to see the reasons this could fail - basically network is not ready or an input parameter is wrong. The socket structure cannot be created (is pvPortMallocSocket() just mapped to pv…

You said “basically network is not ready” I configure all of the requirements. What do you think about what are the missing matters when we look to network ready requirements?
