标题：zlinghe:求助，8019网卡驱动问题
摘要：No.88225求助，8019网卡驱动问题 我现在用51控制8019网卡芯片，采用查询方式收数据。但接收数据的时候只能收几个数据包，然后收到的4个字节的包头就不对了，再往后就干脆全为零了，之后CURR寄存器就为0XFF了。郁闷，到底是怎么回事呢？
这是相关的几个函数：
//8019初始化函数
void RTLInit(BYTE LocalMACAddr[])
{
// BYTE temp;
// int i;
NET_RST=1;
delayms(2);
NET_RST=0;
delayms(100); /* init RTL registers*/
WriteReg(CR,(CR_PAGE0 | CR_ABORT_COMPLETE_DMA | CR_STOP_COMMAND)); /* set page0, stop command. command is stop after power up. */
delayms(10); //确保芯片进入停止状态 WriteReg(DCR_WPAGE0, 0xC8); /* DCR: refer to define of DCR in Rtl8019as.h */
WriteReg(RBCRH_WPAGE0,0);
WriteReg(RBCRL_WPAGE0,0);
//使芯片与网络断开
WriteReg(RCR_WPAGE0, 0x20); /* RCR: refer to define of RCR in Rtl8019as.h */
WriteReg(TCR_WPAGE0, 0x02); /* TCR: refer to define of TCR in Rtl8019as.h */
WriteReg(PSTART_WPAGE0, RECEIVE_START_PAGE); /* Pstart */
WriteReg(PSTOP_WPAGE0, RECEIVE_STOP_PAGE); /* Pstop *///0x80也可以使用
WriteReg(BNRY_WPAGE0, RECEIVE_START_PAGE); /* BNRY */
WriteReg(TPSR_WPAGE0, SEND_START_PAGE0); /* TPSR */
WriteReg(ISR_WPAGE0, 0xFF); /* write FF to clear up all interrupt status */
WriteReg(IMR_WPAGE0,0x0); WriteReg(CR,(CR_PAGE1 | CR_ABORT_COMPLETE_DMA | CR_STOP_COMMAND)); WriteReg(CURR_WPAGE1,RECEIVE_START_PAGE + 1); /* set phisical address */
WriteReg(PRA0_WPAGE1,LocalMACAddr[0]);
WriteReg(PRA1_WPAGE1,LocalMACAddr[1]);
WriteReg(PRA2_WPAGE1,LocalMACAddr[2]);
WriteReg(PRA3_WPAGE1,LocalMACAddr[3]);
WriteReg(PRA4_WPAGE1,LocalMACAddr[4]);
WriteReg(PRA5_WPAGE1,LocalMACAddr[5]); /* MAR0 */
WriteReg(0x07, 0xff);
WriteReg(0x08, 0xff);
WriteReg(0x09, 0xff);
WriteReg(0x0a, 0xff);
WriteReg(0x0b, 0xff);
WriteReg(0x0c, 0xff);
WriteReg(0x0d, 0xff);
WriteReg(0x0e, 0xff);
WriteReg(0x0f, 0xff);
WriteReg(CR,(CR_PAGE0 | CR_ABORT_COMPLETE_DMA | CR_START_COMMAND)); WriteReg(RCR_WPAGE0, 0xCC); /* RCR: refer to define of RCR in Rtl8019as.h */
WriteReg(TCR_WPAGE0, 0x00); /* TCR: refer to define of TCR in Rtl8019as.h */ /* transimit start page */
LastSendStartPage = SEND_START_PAGE0;
StartPageOfPacket = RECEIVE_START_PAGE + 1; /* in the beginning, no packet is in sending */
InSending = FALSE;
/* initial over, start command and receive */
WriteReg(ISR_WPAGE0, 0xFF); /* write FF to clear up all interrupt status */
} /* read rlt ram data to buffer */
void RTLReadRam(WORD address,WORD size,BYTE DT_XDATA * buff)
{
BYTE DT_XDATA * Endp;
BYTE PrePage; /* store page */
PrePage = ReadReg(CR);
RTLPage(0);
WriteReg(RSARH_WPAGE0,(BYTE)((address> > 8)&0x00ff));
WriteReg(RSARL_WPAGE0,(BYTE)address);
WriteReg(RBCRH_WPAGE0,(BYTE)((size> > ......
