Board-level Linux integration, U-Boot, device trees, kernel drivers and peripheral bring-up. Separate power and hardware checks from software adaptation, and define a recoverable boot path.
Classify Yocto shared objects as development symlinks, real unversioned libraries or plugins, then adjust packaging without hiding runtime dependencies in development packages.
Trace Yocto buildpaths warnings to debug records, compiler macro expansion or generated literals, then repair the producer and test location independence.
Resolve each DFU alternate into the MMC backend layout and explicit block range before approving a factory transfer.
Validate transfer extent and source identity after a successful filesystem load, with destination bounds established before reading.
Trace lifecycle boundaries and return values instead of treating a tree listing or an intermediate activation flag as proof of a ready peripheral.
Trace Yocto application overlays from matching machine/recipe flags through backing-mount, helper, overlay and aggregate-service dependencies, then distinguish writable access from persistence.
Trace PACKAGE_CLASSES ordering through writer inheritance, IMAGE_PKGTYPE and rootfs/SDK backend selection, and distinguish secondary package-output failures from image assembly.
Select original, patched or configured archiver outputs by their actual source stage, explain directory-backed originals and out-of-tree configured content, and request companion records separately.
Derive Scarthgap source paths from archive members, per-URI subdir and tar striplevel, distinguish unpack=0 and verify S against the actual unpack output.
Locate uninative configuration, reuse, host-glibc compatibility and installation branches, then interpret native loader and shared-state effects without overstating cache disablement.
