设备上只支持TPM 2.0？ [英] Only TPM 2.0 supported on devices??

问题描述

我从azure iot sdk运行tpm_device_provision时遇到TPM驱动程序错误。

I'm getting a TPM driver error while running tpm_device_provision from the azure iot sdk.

我安装了moby-engine，moby-cli，iotedge和libiothsm- std在具有TPM芯片的ARM设备上。

I've installed moby-engine, moby-cli, iotedge and libiothsm-std on an ARM device that has a TPM chip.

我已经构建了azure-iot-sdk-c（2019-04-11）项目，包括provisioning_client代码。

I've built the azure-iot-sdk-c (2019-04-11) project, including the provisioning_client code.

当我尝试通过以root用户身份执行tpm_device_provision来获取设备上的自动配置信息（运行ubuntu 18.04.2）时，我收到以下错误：

When I attempt to get auto-provisioning information on the device (running ubuntu 18.04.2) by executing tpm_device_provision as the root user, I get the following error(s):

./ tpm_device_provision

设备上安装的TPM芯片支持TPM 1.2，但不支持TPM 2.大多数支持Linux的TPM设备（除英特尔台式机外）都在TPM 1.2，不是TPM 2.0。 （参见kernel.org的文档：devicetree / bindings / i2c / trivial-devices.txt）

The TPM chip installed on the device supports TPM 1.2, but not TPM 2. The majority of linux-supported TPM devices (aside from Intel desktops) are at TPM 1.2, not TPM 2.0. (See for instance kernel.org's documentation: devicetree/bindings/i2c/trivial-devices.txt)

我可以使用其他工具（裤子和Java）打开TPM基于TPM的库。

I'm able to open the TPM just fine using other tools (trousers and a Java-based TPM library).

azure工具在名称以TPM2为前缀的函数中失败，这表明azure iot可能不支持TPM 1.2（？）

The azure tool fails in a function whose name is prefixed with TPM2, suggesting that maybe azure iot doesn't support TPM 1.2 (?)

Microsoft是否支持TPM 1.2？

Is it the case that Microsoft does not support TPM 1.2?

如果是，是否有任何计划和时间表来解决此限制？

If so, are there any plans and a timeframe for fixing this limitation?

谢谢。
