The adventure of porting Zephyr to a hearing aid, a life-changing device that uses almost no power, almost no space and will be produced in millions.
This is the story of molding Zephyr into a project that also supports the most exotic development environments, like those found in the making of an FDA approved medical device like a hearing aid sold to millions of users.
The challenges, to name a few; - Zephyr as a modular component - Porting Zephyr to a custom processor - Making Zephyr (bluetooth stack) endianess portable - Supporting a fully proprietary toolchain - Improving and generalizing tracing infrastructure - Making it run with a lemon as a battery
