According to the manual this is impossible, so I think it's something to do with tpm_validate_command. I think, perhaps, we shouldn't call the getcaps for the command codes until the self test is over, but I need to do more debugging to track down what's going on. I've also got other reports of TPM_RC_COMMAND_CODE failures during self test, so this isn't just my screwed up chip. James
