S3C2410的WINCE BSP添加串口支持 05 source, drive

samwalton

搜索：
void
OEMInterruptDone(DWORD idInt) // @parm Interrupt ID. See <t Interrupt ID's>
依旧找到case SYSINTR_SERIAL:
在其后面添加：
case SYSINTR_SERIAL1:
s2410INT->rINTMSK &= ~BIT_UART1;
s2410INT->rINTSUBMSK &= ~INTSUB_RXD1;
break;
      6、打开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、打开smdk2410.cec文件，添加UART1这个feature。

      我感觉这个改不改没什么关系，反正网上有人这样改了，我也就改了，但是实际内核定制时中并没有添加上这个feature。
      到这里，整个过程就结束了，耗费了我整整一天！其实改动量并不大，但是调试一次光编译就要15分钟，还要下载，烧写，启动～唉，没有仿真器就是麻烦。调了好多次没有成功，就是在注册表的中断号那儿出了问题！
