Init IST by a DLL during boot time

Dear all,
I create a dll to init GPIO27 interrupt and install a IST in wince. The
IST is to capture the falling edge of GPIO27 in wince.

The following is the DLL program
BOOL APIENTRY DllMain( HANDLE hModule, DWORD ul_reason_for_call, LPVOID
lpReserved )
{
......
switch( ul_reason_for_call )
{
case DLL_PROCESS_ATTACH:
RETAILMSG (1, (TEXT(" DLL_PROCESS_ATTACH \r\n")));

//Init GPIO, GPIO27 interrupt, IST subroutine are put here

break;

case DLL_THREAD_ATTACH:
RETAILMSG (1, (TEXT(" DLL_THREAD_ATTACH \r\n")));
break;
case DLL_THREAD_DETACH:
RETAILMSG (1, (TEXT("DLL_THREAD_DETACH \r\n")));
break;
case DLL_PROCESS_DETACH:
RETAILMSG (1, (TEXT(" DLL_PROCESS_DETACH \r\n"))); break;

}//END OF SWITCH

return TRUE;

}

Also in the registry, I modify as below
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\GPIO27INT\]
"Dll"="GPIO27INT.dll"

During boot time, the DLL loaded. Also "DLL_PROCESS_ATTACH" was got. The
interrupt and IST installed properly. Since there are clock pulse on GPIO27
pin already, the IST was operating. However after "DLL_PROCESS_DETACH", the
IST doesnot work.

Are there anything wrong? Thanks for your reply.

You failed to comprehend the need for specific entry points in the DLL for
it to be considered a valid driver that loads from the registry keys you
identified. You should not set up the IST in DllMain but instead defer that
to the xxx_Init() export. Look up the documentation for implementing a
stream driver.

Dear Steve,
Thanks for your reply. I tried to study the stream driver. During boot
time, the DLL loaded. Also enter xxx_Init() of my stream driver. In this
xxx_Init(), I tried to setup a timeout thread. However, the thread didn't
work. During initialization, there is no error message. Are there anything
wrong? Thanks for your reply.
There is my timeout thread subroutine.

BOOL SetupTimeoutThread()
{
g_hevInterruptTimeout=CreateEvent(NULL, FALSE, FALSE, NULL);
if(g_hevInterruptTimeout==NULL)
{RETAILMSG (1, (TEXT(" Inside SetupTimeoutThread CreateEvent error!\r\n")));
return FALSE;
}

g_htISTTimeout=CreateThread(NULL,0,
(LPTHREAD_START_ROUTINE)TimeoutThread,
NULL,CREATE_SUSPENDED,&gdwThreadIDTimeout);
if(g_htISTTimeout==NULL)
{
RETAILMSG (1, (TEXT(" Inside SetupTimeoutThread Createthread error!\r\n")));
return FALSE;
}

if(!CeSetThreadPriority(g_htISTTimeout,10))
{
RETAILMSG (1, (TEXT(" Inside SetupTimeoutThread Thread Priority
error!\r\n")));
return FALSE;
}

ResumeThread(g_htISTTimeout);
return TRUE;
}

void TimeoutThread()
{

while(1)
{
if (WaitForSingleObject(g_hevInterruptTimeout, 200) == WAIT_TIMEOUT)
{
RETAILMSG (1, (TEXT(" Inside TimeoutThread!\r\n")));
gbyTimeoutFlag=1;
}
}

}

Why do you think the thread didn't work? Because you don't see retailmsg "
Inside TimeoutThread!\r\n", no retailmsg at all?

Wherenever you have a
if ( )
{
RETAILMSG
}

Chang it to
if( )
{
RETAILMSG
}
else
RETAILMSG

Print return value of WaitForSingleObject and add one more RETAILMSG at the
beginning of TimeoutThread, then you will sure know how it went.

Dear Mr. Wang,
I tried to modify the code as followings. There are still no retailmsg in
the TimeoutThread.

There are the retailmsg, during boot time.
TEST DLL: INSIDE TES_Init
DLL: Inside SetupTimeoutThread ResumeThread=1.
TEST DLL: EXIT TES_Init

all these retailmsg are of BOOL SetupTimeoutThread(), instead of
TimeoutThread. Do you any idea? Thanks for your help.


void TimeoutThread()
{
DWORD dwTemp;
RETAILMSG (1, (TEXT("DLL: Inside TimeoutThread before while(1)!\r\n")));
while(1) {
dwTemp=WaitForSingleObject(g_hevInterruptTimeout, 200) ==WAIT_TIMEOUT;
if (dwTemp == WAIT_TIMEOUT){
RETAILMSG (1, (TEXT("DLL: Inside TimeoutThread!\r\n")));
gbyTimeoutFlag=1;
}
else
{
RETAILMSG (1, (TEXT("DLL: Inside TimeoutThread else of
WaitForSingleObject ! \r\n")));
}

RETAILMSG (1, (TEXT("DLL: Inside TimeoutThread Value of WaitForSingleObject
=%x,!\r\n"), dwTemp));
}
}

Try the right Thread Procedure

DWORD WINAPI TimeoutThread(LPVOID lpParameter);

instead of

void TimeoutThread();

Dear Bluesphere,
I modified my code and did sysgen again but it didn't work. Is there any
problem on setting thread procedure? Thanks for your reply.

As a test, try to (manually) load your driver after the system has done the
boot.
Also check the return value of ResumeThread
