[FreeRTOS Home] [Live FreeRTOS Forum] [FAQ] [Archive Top] [January 2010 Threads] Problem: new socket Posted by André Fernandes on January 26, 2010 Hello,
I'm trying to implement the code below, but it stops in the line sock = socket(AF_INET, SOCK_DGRAM, 0);
the message is "sys_arch_timeouts: ptask != NULL"
the procedure sequence is:
-lwip_socket (type=0, protocol=100) -alloc_socket (newcon=0x80173c) -sys_sem_wait (sem=0x805ea8) -sys_arch_timeouts () -sys_assert ()
I have already tried a TCP socket but got same problem. I am using lwIP 1.3.0 and freeRTOS 5.3.0. uController: MCF51CN128. Could anyone help me?
void test_UDP_send( void * pvParameters ) { int sock; struct sockaddr_in sLocalAddr, sDestAddr; char reply[]="testing"; char buffer[1024]; int nbytes;
sock = socket(AF_INET, SOCK_DGRAM, 0); memset((char *)&sLocalAddr, 0, sizeof(sLocalAddr)); memset((char *)&sDestAddr, 0, sizeof(sDestAddr));
//Destination sDestAddr.sin_family = AF_INET; sDestAddr.sin_len = sizeof(sDestAddr); sDestAddr.sin_addr.s_addr = htonl(INADDR_BROADCAST); sDestAddr.sin_port = 1234; //Source sLocalAddr.sin_family = AF_INET; sLocalAddr.sin_len = sizeof(sLocalAddr); sLocalAddr.sin_addr.s_addr = htonl(INADDR_ANY); sLocalAddr.sin_port = 1235;
bind(sock, (struct sockaddr *)&sLocalAddr, sizeof(sLocalAddr));
lwip_close(sock); for(;;) { nbytes=lwip_recv(sock, buffer, sizeof(buffer),8); if (nbytes>0){ lwip_sendto(sock, buffer, nbytes, 0, (struct sockaddr *)&sDestAddr, sizeof(sDestAddr)); led_green_on(); vTaskDelay(200); led_off(); vTaskDelay(500); }
lwip_sendto(sock, reply, sizeof(reply), 0, (struct sockaddr *)&sDestAddr, sizeof(sDestAddr)); vTaskDelay( 200 ); //some delay!
} }
RE: Problem: new socket Posted by Dave on January 27, 2010 I suggest posting your question to the lwip mailing list.
RE: Problem: new socket Posted by André Fernandes on January 27, 2010 I did it. Thanks
