" summary

Explains how ARMhf boots from boot ROM to bootloader to kernel and why wrong offsets or wrong DTB stop a device dead, shows using vendor BSPs and matching kernel versions, and recommends a serial/TTL console for debugging when HDMI is absent or driverless. Covers firmware blobs and txt mapping for Wi‑Fi found in the Linux firmware package, contrasts SD card boots with native SATA for reliability, and demonstrates bringing a board and attempting real boots and kernel swaps so attendees can reproduce fixes.
