[Verse 1] When your board won't boot and the kernel screams Silent hardware mocks your engineering dreams Device tree corruption leaves you in the dark Time to hunt the phantom nodes that missed their mark [Chorus] Check proc device tree first, your roadmap to the truth Compatible strings and reg values give you proof Phandle references broken, interrupts gone astray Debug device tree issues, make your hardware obey [Verse 2] Navigate to proc filesystem, device tree awaits Every node becomes a folder, properties as gates Read the actual runtime values, not your source file dream Kernel parsed and loaded shows you what's really seen [Chorus] Check proc device tree first, your roadmap to the truth Compatible strings and reg values give you proof Phandle references broken, interrupts gone astray Debug device tree issues, make your hardware obey [Verse 3] Missing reg addresses haunt your memory maps GPIO controllers vanish into binding gaps Clock references dangle, pointing into void Status equals disabled leaves your drivers unemployed [Bridge] Overlays and fragments scattered in the wind Compare your source against what the kernel pinned Dtc compiler warnings whisper secret clues Address cells and size cells, mind the binding rules [Chorus] Check proc device tree first, your roadmap to the truth Compatible strings and reg values give you proof Phandle references broken, interrupts gone astray Debug device tree issues, make your hardware obey [Outro] When silicon stays silent, don't despair or flee Your answers wait in proc filesystem's device tree
