Yocto Image Package Lists: Explain Why a Recommended Package Appears
Trace why Yocto installs a recommended package and choose between selective recommendation filters, blanket filtering and a hard package exclusion.
-
-
Yocto Package Architecture: Avoid Reusing Machine-Specific Output as Architecture-Independent
Classify Yocto packages using payload and dependency invariants, and diagnose why text-only recipes can still be inappropriate for allarch.
-
Yocto AUTOREV: Understand When a Moving Revision Enters Task Metadata
Explain Yocto AUTOREV resolution, revision-cache behavior, pre-task source lookup, and the separate package-version identity needed before freezing a release revision.
-
Yocto Fetcher Checksums: Diagnose Named Inputs and Cached Downloads
Diagnose Yocto archive checksum failures through named URI flags, download filename collisions, actual mirror selection, done-stamp digest reuse and strict missing-checksum policy.
-
Yocto File Ownership QA: Find Host UID Leakage in Installed Artifacts
Diagnose Yocto host-user-contaminated findings by tracing ownership-preserving copies, respecting Pseudo’s simulated view, and inspecting numeric package ownership.
-
Yocto Kernel Modules: Package the Module for the Kernel ABI Actually Deployed
Trace an out-of-tree Yocto module from selected kernel source and build artifacts through symbol versions, split packages and the kernel actually booted.
-
U-Boot AM335x Board Identity: Follow EEPROM Failure into Pinmux and DDR Selection
Trace AM335x EEPROM failure state into warning-only pinmux handling and concrete DDR defaults, distinguishing unreadable and unsupported identities.
-
U-Boot Boot Timing: Distinguish Timestamp Marks, Accumulated Work and Stage Handoffs
Interpret timestamp marks and repeated-work accumulators correctly, then verify record completeness and cross-stage handoff before optimizing boot time.
-
U-Boot ARM64 Linux Handoff: Audit Registers, Cleanup and the Final Branch
Audit the direct ARM64 Linux entry contract, final architecture branch and board/device cleanup beyond the starting-kernel banner.
-
U-Boot i.MX8MM DDR Training: Trace Failure Returns Before Trusting the Next Stage
Follow i.MX8MM EVK training results through multiple passes, controller initialization and the board wrapper that ignores the return.
