Hi,
I am using C# application with DLL library source code for one of my project. I configured both for 64bt system and tested in windows 64 bit supported board, there it was working fine. But when I configured both for 32 bit system and tested in windows 32 bit supported board, I was getting below errors for 3 of the functions:
System.EntryPointNotFoundException: Unable to find an entry point named 'PldaMemoryWrite32' in DLL 'PLDA.dll'.
at PLDAAPINet.PLDAAPI.PldaMemoryWrite32(UInt32 PCIAgentIndex, UInt32 BarIndex, UInt32 dwOffset, UInt32 dwSize, UInt32[] pWrBuffer)
System.TypeInitializationException: The type initializer for 'HMAPInet.HM_API' threw an exception. ---> System.EntryPointNotFoundException: Unable to find an entry point named 'FIFO_THRESHOLD_VALUE' in DLL 'PLDA.dll'.
at PLDAAPINet.PLDAAPI.FIFO_THRESHOLD_VALUE()
System.TypeInitializationException: The type initializer for 'mPCIE_ADIO16_8F.Form1' threw an exception. ---> System.EntryPointNotFoundException: Unable to find an entry point named 'Get_Target_Hz' in DLL 'PLDA.dll'.
at PLDAAPINet.PLDAAPI.Get_Target_Hz()
Please anyone help me how to overcome this issue as soon as possible.
Thanks and Regards,

You should contact the support of chipset manufacturer for help of their library. I think it can be verified the vendor is www.plda.com based on this slide.
You can either check their KB, or submit a support case after sign up.
Hi @Cheong00 ,
Thanks for your reply.
Same PLDA function was working in 64 bit system, but not in 32 bit system. And also its mentioned that all PLDA functions are supported for both 32bit and 64bit system.
Other two functions FIFO_THRESHOLD_VALUE() and Get_Target_Hz() are added by us only. We have added many other functions , but except for all those I am facing this issue for only those two added functions.
So please guide me how can I solve this issue.
Thanks and Regards,

For third-party PLDA.dll issues, it may be difficult for us to resolve.
But for problems with your custom method, we should be able to try to solve them.
Can you use those custom methods to build a simple dll and reproduce the problem?
If FIFO_THRESHOLD_VALUE() and Get_Target_Hz() are added by yours, I suggest you to check whether the import declaration should point to "PLDA.dll" unless that DLL is provided by yours too.
No idea for the first one with the limited information given.
Hi @Cheong00 ,
Thanks for you reply.
I have included those two functions as shown below:
[DllImport("PLDA.dll", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.Cdecl)]
public static extern UInt32 Get_Target_Hz();
[DllImport("PLDA.dll", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.Cdecl)]
public static extern UInt32 FIFO_THRESHOLD_VALUE();
So both functions are pointing to PLDA.dll only.
Hi @Timon Yang-MSFT ,
Thanks for your reply.
For other DLL also am facing same issues in 32 bit system. Please help me how can I solve this issue.?
I mean you should run "dumpbin /exports PLDA,dll" in your "Developers command prompt for VS201X" to check whether these functions exists.
If not, then either the DLL version you use is incorrect, or these functions are to be provided by some other libraries instead of "PLDA.dll".
