SK-AM64B: Trying to implement secure boot but failing. Wanted to know step by step process

Siril Ganjai
Prodigy 20 points
Part Number: SK-AM64B

Tool/software:

We were trying to perform code signing and generate combined boot for TI AM64 board and we are unable to do so. We'd like to understand the following.

  • Building SBL(Secondary Boot Loader FW), System Firmware, Board Configuration binaries for an HS-SE device
  • How to sign these binaries
  • How to Concatenate them for generating signed binaries for HS-SE device using enterprise Certificate.

We are currently using U-boot for the processes and the ROM boot loader is not booting these binaries. 

We want to know the step-by-step process for building secure binaries so that the ROM boot loader will accept it.

    Hello,

    All the SDKs are designed to automatically generate signed images so you do not need to manually perform all those steps. Please ensure you are booting the correct generated image if the boot is failing.
