CH579M已经收到服务器的log“227 Entering Passive Mode (192,168,2,2,156,38)”并在收到后根据156*256+38的端口号创建了新的socket，但没有后续的“226 Operation successful”响应。而且服务器端一直显示“downloading”状态。
这是新的socket连接代码：
void WCHNET_CreateFTPDatClient( UINT16 *DesPort ,UINT16 *SourPort)
{
uint8_t i;
SOCK_INF TmpSocketInf_3;
uint32_t num = 0; //保存随机数
float down=0,top=999;//区间范围
static const int scale = 1;
extern uint16_t MsTick;
memset((void *)&TmpSocketInf_3,0,sizeof(SOCK_INF));
memcpy((void *)TmpSocketInf_3.IPAddr,mark.ipv4_address,4);
srand((unsigned int)MsTick);//设置当前时间为随机数种子
num = rand() % ( uint32_t )( ( top - down ) * scale ) + ( uint32_t ) (down * scale);//产生0-999之间的随机数，RAND_MAX是生成随机数的最大值
*SourPort = 39000 + num;
TmpSocketInf_3.DesPort = *DesPort; //156*256+38的端口号
TmpSocketInf_3.SourPort = *SourPort;
PRINT("\r\nTmpSocketInf_3.DesPort:%d\r\n",TmpSocketInf_3.DesPort);
PRINT("\r\nTmpSocketInf_3.SourPort:%d\r\n",TmpSocketInf_3.SourPort);
TmpSocketInf_3.ProtoType = PROTO_TYPE_TCP;
TmpSocketInf_3.RecvStartPoint = (UINT32)SocketRecvBuf[1];
TmpSocketInf_3.RecvBufLen = RECE_BUF_LEN ;
i = WCHNET_SocketCreat(&SocketId3,&TmpSocketInf_3);
mStopIfError(i);
i =WCHNET_SocketConnect(SocketId3);
mStopIfError(i);
memset((void *)SocketRecvBuf[SocketId3],'\0',sizeof(SocketRecvBuf[SocketId3]));
ftp.DatMonitor = SocketId3;
}
这是服务器端日志：
