1. Introduction In the previous article titled “How to Install a Linux Virtual Machine”, we explained the installation method for a Linux virtual machine. To build an embedded Linux development environment, it is necessary to configure the cross-compilation environment within the Linux virtual machine. Therefore, this article will introduce the configuration method for the cross-compilation … Read more
As the saying goes, the beginning is always the hardest. When starting out, do you feel completely lost, unable to find your way amidst a sea of new terms while searching online? Even going to the library to look for books seems directionless? With terms like ARM, Linux, and U-Boot, it can be overwhelming. Where … Read more
You may have noticed that among those working in embedded systems, there are far more people researching Linux than those working with WinCE. Many manufacturers also provide documentation primarily focused on Linux. I have always found it hard to understand; in fact, the interface of WinCE is much more visually appealing than that of Linux, … Read more
Many beginners are confused about the differences between Arduino, ARM, Raspberry Pi, and microcontrollers. All four belong to the field of embedded technology, which encompasses a vast body of technical knowledge. In fact, comparing these four is a mistake in itself. Today, I will explain these four technical terms! Arduino Microcontrollers come in many different … Read more
