Re: [Tpm4java-users] Infineon TPM 1.2: demo code won't work

[Martin H. <li...@ma...>]

Markus,

there are two things that should be done:

First, please provide the full stack trace of the exception.

Second, please replace line 24 in Dice. Right now this is:
> Random tpmRandom = TssFactory.getHighLevel().getTpmRandom();

The new code will turn debug information on:
> TssLowlevel low = TssFactory.getLowlevel();
> low.setDebug(true);
> Random tpmRandom = new TssHighLevelImpl(low).getTpmRandom();

When running the program, the raw TPM commands and replies will be
printed on stdout. Given these information, I should be able to see
which problem the TPM is having.

Thanks,
Martin
