    Hi SI,

    HSM Run Time firmware load is supported in both HS-FS and HS-SE devices. The difference between the same are mentioned here -

    For User Modified Custom HSM Firmware, they need HS-SE devices.

    Hi Aakash,

    Thanks for the clarification.

    BTW, what is HSM Run Time firmware?

    When I checked MCU+ SDK UG, HSM Server is one of HSM runtime firmware we provide through MCU+ SDK, right?

    Is it possible to download User modified customer HSM FIrmware after turning to HS-SE device?

    My customer want to release their product with user modified HSM FIrmware on HS-FS device, and then, run user modified HSM FIrmware after signing HS-SE device. Is this scenario possible?

    Thanks and Best Regards,

    SI.

    Actually TIFS-MCU Firmware is TI's HSM Firmware delivered to the customers. HSM Server is a communication model between HSM Firmware and Application (which will act as a HSM Client).

    Customer needs to request for NDA as mentioned in the Academy. This will allow them to use TIFS-MCU package.

    No, TI owns the HSM Run-Time Firmware in case of HS-FS devices to provide easy development of applications etc. However, to ensure customer freedom of use in case of HSM Firmware, the HS-SE devices are introduced with root of trust with the customers.

    Anyways, HS-FS devices are deemed non-secure and fit for development. However, HS-SE devices are considered secure and fit for production.
