[lwip-users] lwip_bind error

[Jin Won Seo]

Hi,

I am developing a receiver module using StellarisWare 10636, LM3S9B96, lwip1.3.2, safeRTOS.

I printed out a certain message on LCD to see if socket is bound properly.

?

1 2 3 4 5 6 7 8 9 10 11 12 13

while((socket_fd = lwip_socket(AF_INET, SOCK_DGRAM, 0)) == 0) {     DisplayString(115, 210 - 10, "  lwip socket error...  ");     //xTaskDelay(CHGD_OPEN_TIME);     xTaskDelay(SECONDS(5));//arbitrary time for test }   //bind socket to the local address and port if(lwip_bind(socket_fd, (struct sockaddr *) &sClient, sizeof(sClient)) == -1) {     lwip_close(socket_fd);     DisplayString(115, 190 - 10, "  bind error  "); }

and lwip_bind() returns -1 as a result "bind error" is displayed on LCD, but I don't see a print-out message in lwip_socket().

I wonder why socket can not be bound properly.

Does anyone have any idea?

Thanks,

Jin
