AM2634: Secure Bootloader

Baljeet Bhatti

Part Number: AM2634

Hi,

I am following sbl_qspi_am263x-cc_r5fss0-0_nortos_ti-arm-clang for booting the application image. But digging bit deeper i found that the function Bootloader_socIsAuthRequired (in bootloader.c) always returns false, so the verification of application firmware image is always skipped.

Is there any other other method to verify application image?

Can you point me to the some example codes on using HSM for Symmetric and Asymmetric cryptography?

Thanks

TI offers Extended Secure boot which verifies the application image before loading the same in the device.

For AM263x, Crypto Drivers example are going to be part of 08.04 release of MCU+ SDK.
Extended Secure Boot is planned for future releases.

TI Secure Boot signing scheme is explained here - Signing binaries for Secure Boot on HS Devices — TISCI User Guide

Thanks and Regards,
