我在 Ubuntu 17.10 上发现了 tpm2.0 芯片。我在 2 版中使用 tpm1.1.0 工具包。(我的笔记本电脑上有物理芯片(。但是,当我尝试清除芯片时,我遇到了错误。
$ tpm2_takeownership -c
Clear Failed ! ErrorCode: 0x921
我也启动了 tpmtest,并且几乎没有更多错误。

我检查了资源管理服务是否激活良好。我在 tpm 上尝试了一些基本命令(tpm2_create、tpm2_load、tpm2_rsaencrypt、tpm2_sign等(,它们都有效。

我是 tpm 技术的新手,所以我想知道这些错误是来自 tpm 本身还是来自包 tpm2-tools。感谢您的帮助!
RC = 0x100 确实不是 100% 错误。我查看了 tpm2-tss 来源。在他们的集成测试中,该错误(并且只有它(在测试启动时被忽略(文件:test/integration/main-sapi.c test/integration/main-esapi.c(
此外,他们将错误描述为标头中的"TPM 未由 TPM2_Startup 初始化或已初始化"。因此,最有可能的是,您的错误只是初始化重复。
