S3C2410的WINCE BSP添加串口支持

s2410INT->rINTMSK = ~BIT_UART1;

break;

搜索：

void

OEMInterruptDisable(DWORD idInt) // @parm Interrupt ID to be disabled. See

還是這一句：case SYSINTR_SERIAL:

在其后面添加：

case SYSINTR_SERIAL1:

s2410INT->rINTMSK |= BIT_UART1;

s2410INT->rINTSUBMSK |= INTSUB_RXD1;

s2410INT->rINTSUBMSK |= INTSUB_TXD1;

s2410INT->rINTSUBMSK |= INTSUB_ERR1;

break;

搜索：

void

OEMInterruptDone(DWORD idInt) // @parm Interrupt ID. See

依舊找到case SYSINTR_SERIAL:

在其后面添加：

case SYSINTR_SERIAL1:

s2410INT->rINTMSK = ~BIT_UART1;

s2410INT->rINTSUBMSK = ~INTSUB_RXD1;

break;

6、打開armint.c文件。

搜索：else if(IntPendVal == INTSRC_UART0)

在其后面添加：

else if(IntPendVal == INTSRC_UART1)

{

SubIntPendVal = s2410INT->rSUBSRCPND;

// Note that we only mask the sub source interrupt - the serial driver will clear the

// sub source pending register.

//

if(SubIntPendVal INTSUB_ERR1)

{

s2410INT->rINTSUBMSK |= INTSUB_ERR1;

}

else if(SubIntPendVal INTSUB_RXD1)

{

s2410INT->rINTSUBMSK |= INTSUB_RXD1;

}

else if(SubIntPendVal INTSUB_TXD1)

{

s2410INT->rINTSUBMSK |= INTSUB_TXD1;

}

else

{

return(SYSINTR_NOP);

}

// NOTE: Don't clear INTSRC:UART1 here - serial driver does that.

//

s2410INT->rINTMSK |= BIT_UART1;

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

return(SYSINTR_SERIAL1);

}

7、打開smdk2410.cec文件，添加UART1這個(gè)feature。

搜索

我感覺這個(gè)改不改沒什么關(guān)系，反正網(wǎng)上有人這樣改了，我也就改了，但是實(shí)際內(nèi)核定制時(shí)中并沒有添加上這個(gè)feature。

到這里，整個(gè)過程就結(jié)束了，耗費(fèi)了我整整一天!其實(shí)改動(dòng)量并不大，但是調(diào)試一次光編譯就要15分鐘，還要下載，燒寫，啟動(dòng)～唉，沒有仿真器就是麻煩。調(diào)了好多次沒有成功，就是在注冊(cè)表的中斷號(hào)那兒出了問題!
