Problem socket() on mqx3.8

[clemNantes]

Hi everyone,

I have a problem using the socket() function in mqx 3.8 when program pass on this function it look like the processor have interruption pending every-time.

My code :

sock_handle = socket(AF_INET, SOCK_STREAM, 0);
                        if(sock_handle == RTCS_SOCKET_ERROR)
                        {
                            printf("socket failed\n\n");
                            //_mqx_exit(0);
                        }else

when I execute this code it launch the isr default function of mqx...

Is anyone have an idea? Or the same problem?

I use mqx 3.8 with codewarrior 10.2 on the TWR-K60N512 dev-Kit

I've found the most typical cause of the default interrupt trap is a stack overflow. I've also found (the hard way) that the yes/no Overflow indication shown in the stack usage MQX RTOS plug-in window isn't always correct. Take a look at task details to make sure.

Shouldn't you use PF_INET (protcol family IP addressing) instead of AF_INET?

Eventually, it is the same.
