S3C2410的WINCE BSP添加串口支持
加入技術(shù)交流群
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(kāi)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(kāi)smdk2410.cec文件，添加UART1這個(gè)feature。

我感覺(jué)這個(gè)改不改沒(méi)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(méi)有添加上這個(gè)feature。
到這里，整個(gè)過(guò)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(xiě)，啟動(dòng)～唉，沒(méi)有仿真器就是麻煩。調(diào)了好多次沒(méi)有成功，就是在注冊(cè)表的中斷號(hào)那兒出了問(wèn)題!
