What Are the Problems with Embedded Linux?

_______________

Linux is ubiquitous. It runs most internet servers, inside Android* smartphones, and is used on millions of embedded systems that, in the past, ran Real-Time Operating Systems (RTOSes). Linux can (and should) be used were possible for embedded projects, but while it gives you extreme choice, it also presents the risk of extreme complexity.

How to Choose a Real-Time Operating System

By Tim Loveless | Principal Solutions Architect on Oct 14, 2019 10:32:00 AM

_______________

Choosing an RTOS is not as simple as choosing a car.  We know about cars; we know their strengths and weaknesses and we intuitively understand compromises like performance vs practicality or luxury vs price.  We see all kinds of vehicles on the road, so the range of available cars is obvious. When choosing an RTOS, the middle ground is crowded—dozens of general-purpose RTOSes with broadly similar characteristics compete.  They all have a scheduler, services, libraries, middleware, technical support, and graphical tools. Any one of them could genuinely do a good job and so choosing between them is a mixture of quantitative metrics (like features and price) and qualitative measures (like past-experience, personal-preference, and reputation).
