[Tpm4java-users] Fw: dll error

[Andrés R. L. <des...@ho...>]

Hi Teena, the tpmddl.dll file is used as a wrapper for the tpm device driver dll, the problem is 
that tpmdll.dll could be wrong. You have to get the source files and recompile the tpmdll.dll file. 
If you look at the code you will see (tpmdll.c):
opentpm = (MyTddli_Open) GetProcAddress(dll, "Tddli_Open");

there is where the tpmdll get the address of the Tddli_Open function from your tpm device driver.

The problem is that the name of the function is wrong, in my case it was:

opentpm = (MyTddli_Open) GetProcAddress(dll, "TDDL_Open");

Note that there are similar instructions in the code:

closetpm = (MyTddli_Close) GetProcAddress(dll, "Tddli_Close");

transmittpm = (MyTddli_TransmitData) GetProcAddress(dll, "Tddli_TransmitData");

You should change them all. The name of the functions in you tmp device driver could be different.

I send you the tpmddl.dll an the c code with the modifications.



Bye,



Andrés.
