Trusted Platform Module TPM2.0 in iMX8 Security Controller

m_mansour — Fri, 29 Nov 2019 11:53:16 GMT

Is it possible to implement the TPM2.0 (Trusted Platform Module) standard with the security controller in iMX8, or are there TPM functions that need an external TPM chip?

Hello,

"We're not aware of any NXP activities to support directly the TPM specification.
But taking a look at internal Community, seems, that it is possible to connect the TPM
using the I2C bus (SMBUS can be controlled via 2-wire interface which is basically
similar with I2C - here [1] you have a datasheet explained that).
