Linux BSP & Board Bring-up

Trace GLIBC locale generation, locale-base installation, application translation packages and final locale archive conversion as distinct Yocto mechanisms.

Diagnose the exact Yocto rpaths and useless-rpaths predicates, then trace CMake build-to-install path rewriting without confusing a narrow QA pass with complete runtime validation.

Reproduce shell task failures from generated run scripts while accounting for stale symlinks, working directories and orchestration outside the replayed body.

Diagnose package upgrade ordering across multiple Yocto builders through binary versions, shared PR Service history, revision request keys and sstate coordination.

A small-flash appliance must keep useful reboot diagnostics while leaving space for product data. Why can configured journal limits and vacuum output differ from expected retention or total use?

A sensor or serial interface works in an interactive shell but the shipped service cannot open it. Which service boundary must be qualified without disabling all hardening?

An appliance has watchdog settings but a stuck application does not recover, or restarting the application is confused with resetting the board. What failure does each observer actually cover?

Diagnose SDK path failures through the actual installer selection rules, ELF interpreter and recognized-section rewrites, text filtering and symlink relocation.

Bind multiple Yocto Git inputs to distinct names, revisions and checkout destinations, then compose their revision identity without confusing those controls.

Diagnose missing dynamic Yocto packages by separating PACKAGES_DYNAMIC promises from do_split_packages discovery, naming, eligibility and optional dependency behavior.
