Enabling Zephyr on Your Hardware Platform
summary
Step‑by‑step recipe for getting Zephyr running on an actual board using i.MX7 Cortex-M4: import vendor HAL sources (he uses an imported FreeRTOS BSP), add Kconfig and CMake entries, write SOC/DTS files plus a DTS fixup header, and add drivers and a board DTS. Practical tips: implement the UART early, use printk and J‑Link for bringup (implement UART first). Notes: Zephyr generates C macros from DTS (Python tooling), and there are already more than 100 boards available so split upstream work into HAL, driver, SOC, and board patches.
