Greatings,
I am trying to establish a raw socket connection between my windows 10 pc (which has a service waiting for incoming connections) and the tiva board (client)
Pc and Board are connected to a hub which is connected to my router.
I have the Ip of my pc as destination, the port on which the pc is accepting is the port the client is trying to connect to.
I am using RTOS on the tiva board and the whole connection is in a task function.
I configured static ip for the board which has the same mask and gateway as the pc (both devices on the same hub).

Basically the connect gets me -1 and fdError() gives me -1 too, I m not sure what -1 means because the doc describes:
" If it succeeds, the function returns 0. Otherwise, a value of -1 is returned and the function fdError() can be called to determine the error:"
I m unsure what I m doing wrong, what is missing.
