SK-AM62B-P1: Does Security Management Subsystem (SMS) play the same role as Trusted Platform Module(TPM)?

Hi Xie,
I'd recommend review AM62x security collaterals available on AM62x security resource download portal.
Have you got access to the portal?

Hi Hong,

I've had access to the files.

It seems the SMS could perform as TPM to some extent.

My team is now developing RTOS sys based on AM62x MCU SDK 9.0.

The problem is that, there is little source for HW security support in the SDK.

I've also found the K3 source in the following link, which includes the usage of sa2ul and examples for crypto.

TexasInstruments/mcupsdk-core-k3: TI MCU+ SDK core source code repository with drivers and example applications for K3 family of MPUs.

Could the K3 source be adapted into am62x directly?

If not, what can I do to make these sources portable for am62x?

Best regards,

Xie
