Here are some tips compiled from our seasoned engineers on what they wish they’d known about embedded linux back when they were “newbs”. Newcomers and seasoned veterans alike should get some good nuggets of information and possibly a fun perspective looking back at our own humble beginnings. We’ll try not to overwhelm you as we make our way through the list. We’re not here to rewrite the books, but do want to provide a personal perspective. If you’re in the camp of people who’ve been using desktop Linux, just be aware embedded Linux is a different animal, especially when it comes to space constraints, different CPU architecture (ARM), resilience to sudden power outages, and inability to install any mainline Linux kernel or distribution you please. And maybe you’re in the microprocessor camp moving towards a more generalized and capable embedded Linux system. Either way, we’ll assume you have at least some knowledge of Linux as we walk through this guide.
