How to Integrate My (Proprietary) Code in Zephyr
summary
Shows exactly how to link a proprietary static library into Zephyr: build the external lib with its own system, package headers alongside a binary blob, and declare it in modules.yml used by West blob. Demonstrates choosing back end via CMake variable versus environment variable, using Cadence HiFi 4 Nature DSP as the case study, and building freestanding apps by set ZEPHYR_BASE & run CMake then Ninja. Includes a proof‑of‑concept out‑of‑tree interrupt driver and the Sound Open Firmware port that successfully runs under Zephyr.
