The Fuse Configuration File is a crucial component in the secure boot process of the Jetson Orin Series, including the AGX, NX, and Nano modules. The provided context mentions that the Jetson Orin Fuse Specification Application Note contains more information about fuses and fuse names for the Orin SoC.

Unfortunately, the context does not provide a direct link to the Jetson Orin Fuse Specification Application Note. However, it does mention that the document is titled “Jetson Orin Fuse Specification Application Note” with a TBD (To Be Determined) document number, version, and date.

To obtain the document, you can try the following options:

  1. Check the NVIDIA website: You can visit the NVIDIA website and search for the document title “Jetson Orin Fuse Specification Application Note.” If the document is available, it should be listed in the search results.
  2. Contact NVIDIA support: You can reach out to NVIDIA support and ask for the document. They may be able to provide you with a link to the document or send it to you directly.
  3. Check the NVIDIA developer portal: The NVIDIA developer portal may have a section dedicated to Jetson Orin documentation, including the Fuse Specification Application Note.

Once you obtain the document, it should provide a detailed explanation of each parameter in the Fuse Configuration File, including their purpose, format, and any specific requirements or constraints.

In comparison to other Jetson modules, the Fuse Configuration File for the Jetson Orin Series is specific to the Orin SoC and may have different parameters and requirements than other modules, such as the Jetson Xavier or Jetson Nano.

To give you a better understanding of the Fuse Configuration File, here is a summary of the information provided in the context:

  • The Jetson Orin Fuse Configuration File is used in the secure boot process of the Jetson Orin Series.
  • The file is specific to the Orin SoC and contains parameters that are unique to this module.
  • The Jetson Orin Fuse Specification Application Note provides more information about fuses and fuse names for the Orin SoC.
  • The document is not available in the provided context, but it can be obtained through the NVIDIA website, support, or developer portal.

In summary, to get the documentation that explains each parameter in the Fuse Configuration File, you should try to obtain the Jetson Orin Fuse Specification Application Note through the NVIDIA website, support, or developer portal.

hello meng.li,

please visit download center for the Jetson Orin Fuse Specification.
besides.. you may see-also Jetson Orin Series Modules Fuse Update Field Services Bulletin for detail update to the FUSE_BOOT_SECURITY_INFO_0 fuse for ALL Jetson Orin Series Modules.

Is there any detailed example steps to show?

  1. generate all the necessary keys
  2. burn them into fuse.

I have study some a secure boot related docs, but I am sure the correct things to enable a orin nano module into secure boot mode. If there is a detailed example steps, I can refer to it, and avoid breaking my orin nano module by accident.

thanks,
LImeng

hello meng.li,

please refer to developer guide, Burn Fuses with the Fuse Configuration file.
you may see-also Topic 300161 for the steps of burning fuses (flash and boot-up successfully) with Orin-NX-8GB for your reference,

In the link Topic 300161, the third step as below
(3) $ sudo ./tools/kernel_flash/l4t_initrd_flash.sh --flash-only -u rsa_priv-3k.pem -v sbk.key jetson-agx-orin-devkit internal
Does this command flash all the secured images that includes bootloader images, kernel, dtb and rootfs into board?

thanks,
LImeng

hello meng.li,

it’s flash to internal storage (QSPI) only, it’s not flashing root file system.
