想实现无线SPI输出，结合sdk的spi_demo例程进行修改，引脚配置什么的都修改好并通过编译，结果在线调试卡在MAP_SPITransfer，请问大家能否帮忙找一下原因呢？

int TcpServerMultiClient(unsigned int usPort)
{
  int serverID;

  SlSockAddrIn_t sAddr;
  SlSockAddrIn_t sLocalAddr;
  int iAddrSize;
  int iStatus;
  int i, Ret,lLoopCount;
  int socketID[5] = {-1, -1, -1, -1, -1};
  //Start TCP Server;
  sLocalAddr.sin_family = SL_AF_INET;
  sLocalAddr.sin_port = sl_Htons((unsigned short)usPort);
  sLocalAddr.sin_addr.s_addr = 0;

  serverID = sl_Socket(SL_AF_INET,SL_SOCK_STREAM, 0);
  if(serverID < 0)
  {
    ASSERT_ON_ERROR(SOCKET_CREATE_ERROR);
  }

  iAddrSize = sizeof(SlSockAddrIn_t);
  iStatus = sl_Listen(serverID, 0);

  if( iStatus < 0 )
  {
    ASSERT_ON_ERROR(sl_Close(serverID));
    ASSERT_ON_ERROR(LISTEN_ERROR);
   }

   UART_PRINT("\n\rListen OK\n\r");
   //

   //
   MAP_SPIReset(GSPI_BASE);

                   (SPI_HW_CTRL_CS |
                   SPI_4PIN_MODE |

   //

   //
   MAP_SPIEnable(GSPI_BASE);
   for(i = 0; i < 5; i ++)
	  {
		  if(socketID[i] < 0)
		  {
			  socketID[i] = sl_Accept(serverID, ( struct SlSockAddr_t *)&sAddr, 

(SlSocklen_t*)&iAddrSize);
		  }

		  if(socketID[i] > 0)
		  {
		      int LOOP,m;
                      for(LOOP = 0;LOOP < 1000 ; LOOP++)
			     {
                                 Ret = sl_Recv(socketID[i], g_cBsdBuf, 1000, 0);
                                 for ( m = 0 ;m < Ret ; m++ )
				  {
				    MAP_SPITransfer(GSPI_BASE,&g_cBsdBuf[m],0,10,
				      			SPI_CS_ENABLE|SPI_CS_DISABLE);
				    
				    UART_PRINT("%s",&g_cBsdBuf[m]);
				   }
				  memset(g_cBsdBuf,0,sizeof(g_cBsdBuf));
	                      }
		  }
	  }

 	  for(i = 0; i < 5; i ++)
	  {
		  sl_Close(socketID[i]);
		  socketID[i]= -1;
	  }

}

这都卡住的地方
