My OS image startup process is stalled on loading symbols for _SERIAL.DL
the latest messages from debug output window are:
========================================================================================================
4294773656 PID:23c4948e TID:23c76eb6 0x83c49000:

Loaded symbols for 'D:\MYWORK\LINDA\RELDIR\SITSANGDEBUG\XSC1BD_SERIAL.DLL'
=========================================================================================================

The serial driver was cloned from lubbock.

the PDD source should be
D:\WINCE420\PLATFORM\Sitsang\drivers\SERIAL\XSC1_SER16550\
and ...\SERIAL\XSC1_SerialPdd\

MDD source should be
D:\WINCE420\PUBLIC\COMMON\OAK\DRIVERS\SERIAL\COM_MDD
and ..\SERIAL\COM_MDD2

Am I right? I am not sure why there are two MDD's ?

In the DllEntry of MDD file ((SerialDllEntry() of MDD; DllEntry() of MDD2))

there is a statement:
---------------------------------------------
{
    if ( dwReason == DLL_PROCESS_ATTACH ) {
        DEBUGREGISTER(hinstDll);
        DEBUGMSG (ZONE_INIT, (TEXT("serial port process attach\r\n")));
---------------------------------------------

But why I can not see the debug messagae "serial port process attach";

What should winCE do before call into DllEntry?

Thanks a lot!!
