Jetson Build Source

This is the build orchestrator for Jetson BSP kernel-side artifacts. It sits between source customization and image deployment, rebuilding device trees, out-of-tree modules, or the kernel itself based on what changed in your bsp_sources checkout. Four build modes (dt, oot, kernel, full) auto-select from the dirty repo set, or you can force one. The skill owns composite DTB overlay registration and delegates all build primitives to NVIDIA's upstream Makefiles rather than duplicating logic. It writes a manifest that jetson-promote-image reads at deploy time to stage rebuilt artifacts into the BSP image tree. Typical flow is auto-chained after a customize step, but you'll invoke it manually when pulling commits from teammates or recovering from interrupted builds.

Build BSP Source

Purpose

Rebuild the kernel-side artifacts (DTBs, OOT modules, in-tree modules, kernel Image) implied by changes under <source.root_path>/bsp_sources/, and write a manifest that /jetson-promote-image reads to stage those outputs into the BSP image. The skill never writes into <bsp_image.root_path> itself.

Prerequisites

Active target-platform profile with bsp_image: and source.toolchain: resolved (run /jetson-init-image and /jetson-init-source first).
<source.root_path>/bsp_sources/ populated with the kernel-side checkout layout /jetson-init-source materializes.
<bsp_image.root_path>/Linux_for_Tegra/source/kernel_src_build_env.sh present (extracted from public_sources.tbz2).
Host packages: flex, bison, libssl-dev (hard); git, build-essential, bc, zstd (warn-only).
Cross-toolchain at ${source.toolchain}gcc resolvable on disk.
