Porting U-Boot and Linux on New ARM Boards: A Step-by-Step Guide
summary
Step‑by‑step recipe to get U‑Boot and Linux running on an i.MX6 custom board: create board file, Kconfig, defconfig, board header, makefile and DTS, enable drivers in Kconfig and wire up pinmux. Uses U‑Boot, Linux kernel, device tree, Kconfig/defconfig and basic driver inspection. Result is small patches — 510 lines of U‑Boot patches with ~100 lines of pinmux, a few lines in arch Kconfig and makefiles, and ~1,000 lines for Linux DTS/config — Ethernet, I2C, eMMC/SD, PCIe and audio boot and work after a U‑Boot/kernel bump.
