关于stm32f4以太网通讯，HAL库，搞了很久了，一直不通

我是用原子的程序，只是改成了HAL库，电脑做服务器，开发板做客户端，
void tcp_client_test(void)
{
struct tcp_pcb *tcppcb;    //¶¨òåò»¸öTCP·tÎñÆ÷¿ØÖÆ¿é

extern ip4_addr_t  rmtipaddr;    //Ô¶¶ËipμØÖ· //这个定义和标准库的不一样吗，这是标准库的 struct ip_addr rmtipaddr;    //Ô¶¶ËipμØÖ·

uint8_t key;
uint8_t res=0;
uint8_t t=0;
uint8_t connflag=0; //á¬½ó±ê¼Ç

tcp_client_set_remoteip();//ÏèÑ¡ÔñIP
printf("KEY0:Send data\r\n");
printf("KEY_UP

uit\r\n");
printf("Local IP:%d.%d.%d.%d\r\n",IP_ADDRESS[0],IP_ADDRESS[1],IP_ADDRESS[2],IP_ADDRESS[3]);
printf("Remote IP:%d.%d.%d.%d\r\n",remoteip[0],remoteip[1],remoteip[2],remoteip[3]);//远端ip
printf("Remote Port:%d\r\n",TCP_CLIENT_PORT);//端口号
printf("STATUS

isconnected\r\n");
tcppcb=tcp_new(); //创建一个控制块
if(tcppcb) //
{//程序到这就是连不上
IP4_ADDR(&rmtipaddr,remoteip[0],remoteip[1],remoteip[2],remoteip[3]);
tcp_connect(tcppcb,&rmtipaddr,TCP_CLIENT_PORT,tcp_client_connected); //连接到服务器
}else res=1;
while(res==0)
{
key=KEY_Scan(0);
if(key==WKUP_PRES)break;
if(key==KEY0_PRES)//KEY0°′ÏÂáË,·￠Ëíêy¾Y
{
tcp_client_usersent(tcppcb); //·￠Ëíêy¾Y
}
if(tcp_client_flag&1<<6)//êÇ·ñêÕμ½êy¾Y?
{
printf("%d",tcp_client_recvbuf);//ÏÔê¾½óêÕμ½μÄêy¾Y
tcp_client_flag&=~(1<<6);//±ê¼Çêy¾YòÑ¾-±»′|àíáË.
}

lwip_periodic_handle();

t++;

这还用cube自动生成的配置函数
void MX_LWIP_Init(void)
{
  /* IP addresses initialization */
  IP_ADDRESS[0] = 192;
  IP_ADDRESS[1] = 168;
  IP_ADDRESS[2] = 1;
  IP_ADDRESS[3] = 30;
  NETMASK_ADDRESS[0] = 255;
  NETMASK_ADDRESS[1] = 255;
  NETMASK_ADDRESS[2] = 255;
  NETMASK_ADDRESS[3] = 0;
  GATEWAY_ADDRESS[0] = 192;
  GATEWAY_ADDRESS[1] = 168;
  GATEWAY_ADDRESS[2] = 1;
  GATEWAY_ADDRESS[3] = 1;

  /* Initilialize the LwIP stack without RTOS */
  lwip_init();

  /* IP addresses initialization without DHCP (IPv4) */
  IP4_ADDR(&ipaddr, IP_ADDRESS[0], IP_ADDRESS[1], IP_ADDRESS[2], IP_ADDRESS[3]);
  IP4_ADDR(&netmask, NETMASK_ADDRESS[0], NETMASK_ADDRESS[1] , NETMASK_ADDRESS[2], NETMASK_ADDRESS[3]);
  IP4_ADDR(&gw, GATEWAY_ADDRESS[0], GATEWAY_ADDRESS[1], GATEWAY_ADDRESS[2], GATEWAY_ADDRESS[3]);

  /* add the network interface (IPv4/IPv6) without RTOS */
  netif_add(&gnetif, &ipaddr, &netmask, &gw, NULL, &ethernetif_init, &ethernet_input);

  /* Registers the default network interface */
  netif_set_default(&gnetif);

  if (netif_is_link_up(&gnetif))
  {
/* When the netif is fully configured this function must be called */
netif_set_up(&gnetif);
  }
  else
  {
/* When the netif link is down this function must be called */
netif_set_down(&gnetif);
  }
