验证密码的这个函数返回-2 MI_ERR[mw_shl_code=c,true]PcdAuthState(PICC_AUTHENT1A, 1, DefaultKey, g_ucTempbuf);//验证卡片密码[/mw_shl_code]

单步调试发现是此函数下
[mw_shl_code=c,true]char PcdAuthState(unsigned char auth_mode,unsigned char addr,unsigned char *pKey,unsigned char *pSnr)
{
    char status;
    unsigned int  unLen;
    unsigned char i,ucComMF522Buf[MAXRLEN];

    ucComMF522Buf[0] = auth_mode;
    ucComMF522Buf[1] = addr;
//    for (i=0; i<6; i++)
//    {    ucComMF522Buf[i+2] = *(pKey+i);   }
//    for (i=0; i<6; i++)
//    {    ucComMF522Buf[i+8] = *(pSnr+i);   }
    memcpy(&ucComMF522Buf[2], pKey, 6);
    memcpy(&ucComMF522Buf[8], pSnr, 4);
   
    status = PcdComMF522(PCD_AUTHENT,ucComMF522Buf,12,ucComMF522Buf,&unLen);
    if ((status != MI_OK) || (!(ReadRawRC(Status2Reg) & 0x08)))
    {   
                        status = MI_ERR;
                        u4_printf("MI_ERR");
                }
   
    return status;
}[/mw_shl_code]

的[mw_shl_code=c,true](!(ReadRawRC(Status2Reg) & 0x08))[/mw_shl_code]这个没有成功

查看手册，没大明白哪里的问题



请帮忙看一看
