Many people often ask this question, so here is a summary for everyone’s reference. It must be stated that the following steps are targeted at Linux systems and do not focus on WinCE. You may notice that among those engaged in embedded systems, there are far more people researching Linux than those working with WinCE. … Read more
For embedded Linux systems, the process from powering on to the operating system startup requires a boot process, which is reflected in the boot program, known as the Bootloader. Concept and Role of Bootloader The Bootloader is the boot program for embedded systems, and it is the first program that runs after the system powers … Read more
Generally speaking, manufacturers purchase various programmable ICs from semiconductor manufacturers, and the data area is blank. Before assembly, the latest version of the control program and data can only be written using an IC programmer. This is a necessary process, more important than IC testing. Generally, it is completed by the final electronic manufacturer, which … Read more
What is a map file? In simple terms, a map file is a mapping file that combines programs, data, and IO space after compilation by the compiler. Many highly skilled engineers first think of analyzing the map file when encountering memory overflow or out-of-bounds situations. The map file provides important information such as function sizes … Read more
