This page provides examples and usage notes for common tasks/issues related to typical embedded Linux systems.
==How to write <code>.wic</code> image files to SD cards==
Yocto build system can generate [https://www.yoctoproject.org/docs/2.4.2/dev-manual/dev-manual.html#creating-partitioned-images-using-wic <code>.wic</code> image files]. These files are usually written to SD cards to create bootable devices.
The simplest way to write such images is to use [https://www.balena.io/etcher/ Balena Etcher] tool, which is available for Linux, macOS, and Windows hosts. Using Etcher is straightforward, nonetheless many tutorials and examples are available on the Internet.
Advanced users can also use the well-known [https://en.wikipedia.org/wiki/Dd_(Unix) <code>dd</code>] utility. This tool should be avoided unless the user knows what they are doing. If the target device is not specified properly, <code>dd</code> can wipe out all the data on host's disk drive! For more details, see for instance [https://opensource.com/article/18/7/how-use-dd-linux this article].
