9 Summary

The minimal platform support framework in U-Boot and Linux accelerates TI AM62x board bring-up from weeks to hours, with this application note providing a structured, step-by-step roadmap for custom board-porting efforts. By utilizing this modular approach (which covers iterative testing, debugging, and documentation) developers can efficiently validate hardware and apply these scalable methodologies to other TI K3 SoCs and ARM-based processors.
