I have a small problem and cant work out what i am doing wrong.
I have stripped out the code to this and this hangs in udp_sendto waiting on a
mbox
int sock;
int onBool = 1;
int err;
struct sockaddr_in addr;
memset(&addr, 0, sizeof(addr));
addr.sin_family = AF_INET;
addr.sin_addr.s_addr = htonl( (239<<24)|(255<<16)|(255<<8)|(250));
addr.sin_port = 50050;
sock = socket(PF_INET, SOCK_DGRAM, 0);
// err = setsockopt( sock, SOL_SOCKET, SO_REUSEADDR, (char *) &onBool,
sizeof (int));
err = bind( sock, (struct sockaddr *)&addr, sizeof(struct sockaddr));
err = sendto( sock, "Hello", 5, 0, (struct sockaddr *)&addr, sizeof(
addr));
closesocket( sock);
Any ideas, as i get no errors, also port 239.255.255.250 is opened as multicast
but i am not even getting data to be passed to the ethernet chip.
