Secure Boot Components

Where the BR-BCT table resides.

Dear vishal.gupta,

tegra194-br-bct files are in /drive-t186ref-foundation/platform-config/bct/t19x/bootrom
Please help to check the folder on your hostPC. Thanks.

I am really sorry for asking the incomplete question. I wanted to ask, Where the BR-BCT file will be stored on device. Is there any way to ensure the integrity of BR-BCT file, as this file is the input for Boot-ROM and my understanding is that the Boot-ROM will be the root of Trust for secure boot chain. So how NVIDIA is ensuring the integrity of BR-BCT or other BCT files.

Dear vishal.gupta,

Could you please refer to “Boot Loader Architecture” part in our doc for this topic?
