Questions about T26x BCT

Robotics & Edge Computing Jetson Systems Jetson Thor

Hi,

I’m working on a Jetson Thor platform (T26x, Jetson Linux r38.2.1) and bringing up a custom carrier board based on the Jetson Thor Adaptation and Bring-Up guide.

I have two questions related to the BCT documentation:

  1. T26x BCT (Boot Configuration Table) Deployment Guide link is not working

In the Jetson Thor Adaptation and Bring-Up page, it says:

For information about customizing the configuration files, refer to the T26x BCT (Boot Configuration Table) Deployment Guide.

I can’t find a valid link for this document in the online Jetson Linux Developer Guide (r38.2.1); every reference to “T26x BCT Deployment Guide” appears to be non-clickable or unavailable.

Is the T26x BCT Deployment Guide publicly available?

If yes, could you provide the correct download link or file name/location?

If not yet public, is there any recommended alternative document we should use for T26x BCT details?

  1. Is T26x BCT design the same as T23x? Where to find detailed T26x BCT documentation?

The Developer Guide has a detailed description of the T23x BCT here:
T23x Boot Configuration Table (BCT) Introduction:

Architecturally, is the T26x BCT design essentially the same as the T23x BCT design described in that page?

Are there T26x-specific differences in the BCT structure or fields that are not covered by the T23x document?

Where can I find detailed T26x BCT documentation?

Any pointer to the correct document or official guidance for T26x BCT customization would be very helpful.

Thanks in advance!

Hi LeoChang_8,

Basically, the BCT configuration for T234 and T26x should be similar.
You can refer to the documentation for T234 first.

I will check with internal about the broken link for T26x.

Hi LeoChang_8,

I’ve checked with internal that the following link should be valid for T26x rather than T23x as its title.
T23x Boot Configuration Table — NVIDIA Jetson Linux Developer Guide
r38.2.1 does not support Orin(T234) series.
Pleas just refer to that document for T26x BCT configuration and we will update the developer guide for later release.
