Surprisingly, this ancient 8086, XT/AT level “antique” can run Linux? That’s right—ELKS (Embeddable Linux Kernel Subset), a mini Linux system specifically designed for 16-bit x86 platforms without an MMU. Next, let’s discuss what it is, its uses, its pain points, and its pros and cons. What exactly is ELKS? ELKS is an early branch of … Read more
In previous articles, we discussed the overall ecosystem of embedded Linux and provided a hands-on guide on how to compile firmware using Buildroot. This time, we will focus on how to use Buildroot to package custom software into the firmware. This article will first discuss the concept of the platform daemon and provide a simple … Read more
Stop getting caught up in the hype; microcontrollers and embedded Linux are not the factors that determine your ceiling. Some students see job postings for Linux positions offering monthly salaries of 20,000 to 30,000 and get excited, thinking they can earn that much too. However, they fail to consider the cost of getting from their … Read more
