S3C2410的WINCE BSP添加串口支持 02 return, points, 源文件

samwalton

然后修改下这个地方：
MapIrq2SysIntr(DWORD _Irq)
{
if( _Irq<=19 )
return ( SYSINTR_FIRMWARE + _Irq );
else
return (0xffffffff);
}
3、打开串口源文件中ser2410_hw.c文件。
搜索：
S2410_SetSerialIOP(
PVOID pHead // @parm points to device head
)
将其函数改为：
{
PS2410_UART_INFO pHWHead = (PS2410_UART_INFO)pHead;
PSER_INFO pHWHead1 = (PSER_INFO)pHead;
RETAILMSG(DEBUGMODE, (TEXT("S2410_SetSerialIOP ")));
if(pHWHead1->dwIOBase == 0x50004000)
{
#if USEVIRTUAL

接着搜索：
SL_Init(

UINT8 RegStride, // Stride amongst the 16550 registers
EVENT_FUNC EventCallback, // This callback exists in MDD
PVOID pMddHead, // This is the first parm to callback
PLOOKUP_TBL pBaudTable // BaudRate Table
)
在PS2410_UART_INFO pHWHead = (PS2410_UART_INFO)pHead;这一句后面添加：
PSER_INFO pHWHead1 = (PSER_INFO)pHead;
