Feedback form is now closed.
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
