Boot Time Optimizations - Alexandre Belloni, Adeneo-Embedded

Sign up or log in to save this to your schedule and see who's attending!

A common problem faced by automotive vendors when embedding Linux is the long boot time before the system is functional. There are many ways to improve boot up time. For a particular project, we had to answer a CAN message from Linux userspace in less than 420 ms from going out of CPU reset. We will describe our methodology and the techniques we finally chose to implement in that particular use case. We will also detail how we measured the boot time efficiently. A live demo will show the results of our work.
