What problem does it solve?

Manually rebuilding kernel-side BSP artifacts (DTBs, OOT modules, kernel Image) after source changes under bsp_sources/ is error-prone and inefficient, as it requires manually following NVIDIA's full build recipe even when only a subset of artifacts are affected by recent changes.

Core Features & Use Cases

• Dirty-repo aware build modes: Auto-detects modified source repositories to run only the required build mode (dt, oot, kernel, or full) instead of the full build chain, saving significant time on incremental changes.
• Composite overlay registration: Automatically handles build, Makefile, and flash configuration registration for kernel device tree custom overlays, ensuring custom DT changes are correctly included in rebuilt artifacts.
• Trace-to-dirty manifest generation: Produces a manifest listing only artifacts affected by source changes, which downstream promotion steps use to copy only relevant files to the BSP image, avoiding baseline divergence noise.
• Use Case: A BSP engineer making a device tree change for a custom carrier board can run this skill to automatically rebuild only the affected DTBs, register the custom overlay, and generate the manifest for promotion, eliminating manual make command errors and missed registration steps.

Quick Start

Invoke the jetson-build-source skill with no argument after making source changes under bsp_sources/ to auto-detect the required build mode, rebuild affected kernel artifacts, and generate the manifest for downstream promotion steps.
