正点原子407开发板SAL实验遇阻

各位好，今天想研究一下RT的SAL组件，配置了使能标准BSD SOCKET  结果总是connect failed  ，贴上我的代码帮忙分析一下：#define SERVER_HOST   "172.20.2.170"
#define SERVER_PORT   1234

int netdev_set_ipaddr_test(int argc, char **argv)
{

struct sockaddr_in server_addr;
		int sockfd = -1;
	  if ((sockfd = socket(AF_INET, SOCK_STREAM, 0)) < 0)
    {
        rt_kprintf("Socket create failed.<br>");
        return -RT_ERROR;
    }
		//    /* 初始化预连接的服务端地址 */
    server_addr.sin_family = AF_INET;
    server_addr.sin_port = htons(SERVER_PORT);
    server_addr.sin_addr.s_addr = inet_addr(SERVER_HOST);
    rt_memset(&(server_addr.sin_zero), 0, sizeof(server_addr.sin_zero));
		
	if (connect(sockfd, (struct sockaddr *)&server_addr, sizeof(struct sockaddr)) < 0)
    {
        rt_kprintf("socket connect failed!<br>");
        closesocket(sockfd);
        return -RT_ERROR;
    }
	   else
    {
        rt_kprintf("socket connect success!<br>");
    }
		send(sockfd,"hello socket",10,0);
		closesocket(sockfd);

}
跟踪调试发现
int connect(int s, const struct sockaddr *name, socklen_t namelen)
{
    int socket = dfs_net_getsocket(s);

return sal_connect(socket, name, namelen);
}
这里 socket=0
