AM2634-Q1: Usage of HSMRt in the SBL

Karthikeyan Vijayan

Part Number: AM2634-Q1

Hi Team,

I'm just using QSPI SBL prebuild binary (Not secure boot), Do i need to consider this memory region? " MSRAM_HSMRT : ORIGIN = 0x70027800 , LENGTH = 0x40000 "

Is this HSMRt will be play any role during SBL copies the APP binary to RAM?

Thanks in advance

Hi Karthikeyan Vijayan,

HSM Run Time provides following services -

https://software-dl.ti.com/mcu-plus-sdk/esd/AM263X/latest/exports/docs/api_guide_am263x/DRIVERS_HSMCLIENT_PAGE.html

Some of them are valid for HSFS+HSSE and some of them are only for HSSE devices. If you don't require these services, you can choose to skip them in HSFS devices.

For more understanding on Security in AM26x devices - https://dev.ti.com/tirex/explore/node?node=A__AKM3smmsVVn7tYZAiWfuSA__AM26X-ACADEMY__t0CaxbG__LATEST

I hope this helps.

Best Regards,
Aakash
