  • what does "enabled PMIC" mean?

    Did you add the driver to your bib file?

    Did you add registry settings to your reg file?

    Did you check to see if the driver and registry settings are in your OS?

    Are there any debug messages?

    How do you know that it isn't getting loaded?

  • Hello Bruce,

    I have added driver entry in bib file and reg file as well.

    I see them in ce.bib and regini.ini. 

    I used regedit.exe after loading the OS to see the registry, pmicPdk_mc13892.dll is present under drivers->Builtin structure.

    No debug messages, its not getting loaded when I checked using KITL.

  • can you post the Bib file and reg file entries for the driver here? we can have a look

  • Reg and/Or Bib file settings for the mentioned dll not loading is wrong.

    There is no other reason that we can guess.

  • Your driver DLL name you have mentioned is " pmicPdk_mc13892.dll"

    in your bib file. But the same you have mentioned in reg file as "Dll"="pmicpdk_mc13892.dll"

    Check the two names.

    The DLL name should remain same in the sources file, bib file and the reg file.

    Hope this will help.

  • Hey Misbah,

    I have tried changing the name in reg file according to bib file but the same result..

    I have a doubt on Prefix name.. 

    Does it matter ??

    I am using the same name in dll entry and everywhere else but still same result..

  • Lets check one by one :-

    1. What is the name of the driver DLL while compiling in sources file ?

    Give the exact name in bib file and reg file. Check the same DLL is being generated after compiling or not ?

    2. Prifix in reg file should remain same what you have mentioned in your driver def file and your driver source file (function entry points eg XXX_Init)

    3. Check is the variable in project batch file "BSP_NOPMIC" is reset as

    set BSP_NOPMIC= ?

    Double check all this parameters. Your problem lies there only .

  • 1. pmicPdk_mc13892.dll is the name of my dll in sources file.. Tried giving the same name in reg and bib files.. And same dll is getting created after compiling when I checked release directory...

    2. My def file looks like this... I guess prefix matches with the def file... 



    3. BSP_NOPMIC=  , this is the setting in batch file...

  • Increase the driver load order from 2 to a higher value in reg file.

    How are you confirming yourself that driver is not getting loaded ?

    It can be that it is getting loaded but unloaded immediately due to error ?

    Give print messages in driver's Entry function such as XXX_Init and XXX_Exit

    Also give print messages under DLLmain as :

    BOOL WINAPI DllEntry(HINSTANCE DllInstance, ULONG Reason, LPVOID Reserved)
        RETAILMSG( 1, (TEXT("Driver: DllEntry\n")));
        switch (Reason) {
            case DLL_PROCESS_ATTACH:
                RETAILMSG( 1, (TEXT("Driver: DLL_PROCESS_ATTACH\n")));
                /* If dpCurSettings is not implemented, this line should be removed.*/

            case DLL_PROCESS_DETACH:
                RETAILMSG( 1, (TEXT("Driver: DLL_PROCESS_DETACH\n")));


        return TRUE;

    See what is happening ?

  • Hi,

    Driver is not even getting loaded and unloaded, this I confirmed using KITL. I confirmed that its not at all loading using KITL itself.

    And I changed the order to 10 still the same result.

    I am not getting any prints in either Attach or init functions.

    I am trying to write a new driver with different Prefix, a sample driver. Then planning to copy the files of pmic driver.

  • Check the log output. It should tell you something about what goes wrong of why .

    Try loading your driver dynamically (just a test program that uses activatedevice() to load your driver)

    Just a wild guess but the if the dll is part of a XIP region (XIP_REGION block specified in provided reg snippet), then is the dll is located in the correct Memory region (NANDIMAGE/NK config.bib)?

  • Yes, good idea try loading dynamically the driver using ActivatedeviceEx

    Also try removing "; @XIPREGION IF PACKAGE_OEMDRIVERS" it from reg file for testing.
