pRegBase = (PUCHAR)pHWHead->s2410SerReg;

#else

pRegBase = (PUCHAR)UART2_BASE;

pHWHead->s2410SerReg = (S2410_UART_REG *)pRegBase;

#endif

}

else

{

把這其中的代碼修改為以下代碼

}

if(pHWHead1->dwIOBase == 0x50004000)

{

pHWHead->bINT = BIT_UART1;

pHWHead->bTxINT = INTSUB_TXD1;

pHWHead->bRxINT = INTSUB_RXD1;

pHWHead->bErrINT = INTSUB_ERR1;

#if USEVIRTUAL

pHWHead->s2410SerReg = (S2410_UART_REG *)v_pUART1regs;

pRegBase = (PUCHAR)pHWHead->s2410SerReg;

#else

pRegBase = (PUCHAR)UART1_BASE;

pHWHead->s2410SerReg = (S2410_UART_REG *)pRegBase;

#endif

}

else if(pHWHead1->dwIOBase == 0x50008000)

{

pHWHead->bINT = BIT_UART2;

pHWHead->bTxINT = INTSUB_TXD2;

pHWHead->bRxINT = INTSUB_RXD2;

pHWHead->bErrINT = INTSUB_ERR2;

#if USEVIRTUAL

pHWHead->s2410SerReg = (S2410_UART_REG *)v_pUART2regs;

pRegBase = (PUCHAR)pHWHead->s2410SerReg;

#else

pRegBase = (PUCHAR)UART2_BASE;

pHWHead->s2410SerReg = (S2410_UART_REG *)pRegBase;

#endif

}

else

{

pHWHead->bINT = BIT_UART0;

pHWHead->bTxINT = INTSUB_TXD0;

pHWHead->bRxINT = INTSUB_RXD0;

pHWHead->bErrINT = INTSUB_ERR0;

#if USEVIRTUAL

pHWHead->s2410SerReg = (S2410_UART_REG *)v_pUART0regs;

pRegBase = (PUCHAR)pHWHead->s2410SerReg;

#else

pRegBase = (PUCHAR)UART0_BASE;

pHWHead->s2410SerReg = (S2410_UART_REG *)pRegBase;

#endif

}

再搜索：

if ( pHWHead->UseIrDA )

{

pHWHead->pUFTXH = (volatile unsigned char *)(v_pUART2regs->rUTXH);

pHWHead->pUFRXH = (volatile unsigned char *)(v_pUART2regs->rURXH);

}

else

{

把這其中的代碼修改為以下代碼

}

if(pHWHead1->dwIOBase == 0x50004000)

{

pHWHead->pUFTXH = (volatile unsigned char *)(v_pUART1regs->rUTXH);

pHWHead->pUFRXH = (volatile unsigned char *)(v_pUART1regs->rURXH);

}

else if(pHWHead1->dwIOBase == 0x50008000)

{

pHWHead->pUFTXH = (volatile unsigned char *)(v_pUART2regs->rUTXH);

pHWHead->pUFRXH = (volatile unsigned char *)(v_pUART2regs->rURXH);

}

else

{

pHWHead->pUFTXH = (volatile unsigned char *)(v_pUART0regs->rUTXH);

pHWHead->pUFRXH = (volatile unsigned char *)(v_pUART0regs->rURXH);

}

4、打開ser2410_ser.c文件。

搜索：

const HWOBJ IoObj = {

THREAD_AT_INIT,

SYSINTR_SERIAL,

(PHW_VTBL) IoVTbl

};

在其后面添加：

const HWOBJ Io1Obj = {

THREAD_AT_INIT,

SYSINTR_SERIAL1,

(PHW_VTBL) IoVTbl

};

const HWOBJ Io2Obj = {

THREAD_AT_INIT,

SYSINTR_IR,

(PHW_VTBL) IoVTbl

};

接著搜索：

const PCHWOBJ HWObjects[] = {

IoObj,

IrObj

};

將其修改為：

const PCHWOBJ HWObjects[] = {

IoObj,

Io1Obj,

Io2Obj

};

再搜索：

GetSerialObject(

DWORD DeviceArrayIndex

)

將其函數(shù)改為：

{

PHWOBJ pSerObj;

DEBUGMSG(DEBUGMODE,(TEXT(GetSerialObject : DeviceArrayIndex = %d ), DeviceArrayIndex));

// Now return this structure to the MDD.

if ( DeviceArrayIndex == 2 )

{

RETAILMSG(1,(TEXT(GetSerialObject Io2Obj )));

pSerObj = (PHWOBJ)(Io2Obj);

}

else if(DeviceArrayIndex == 1)

pSerObj = (PHWOBJ)(Io1Obj);

else

pSerObj = (PHWOBJ)(IoObj);

return (pSerObj);

}

5、打開cfw.c文件，這就是中斷處理。

搜索：

BOOL

OEMInterruptEnable(DWORD idInt, // @parm Interrupt ID to be enabled. See for a list of possble values.

LPVOID pvData, // @parm ptr to data passed in in the call

DWORD cbData) // @parm Size of data pointed to be

找到這一句：case SYSINTR_SERIAL:

在其后面添加：

case SYSINTR_SERIAL1: // Serial port1.

s2410INT->rSUBSRCPND = (INTSUB_RXD1 | INTSUB_TXD1 | INTSUB_ERR1);

s2410INT->rINTSUBMSK = ~INTSUB_RXD1;

s2410INT->rINTSUBMSK = ~INTSUB_TXD1;

s2410INT->rINTSUBMSK = ~INTSUB_ERR1;

s2410INT->rSRCPND = BIT_UART1;

// S3C2410X Developer Notice (page 4) warns against writing a 1 to a 0 bit in the INTPND register.

if (s2410INT->rINTPND BIT_UART1) s2410INT->rINTPND = BIT_UART1;
