Embedded Linux Development using Yocto Projects - Second Edition

By: Otavio Salvador, Daiane Angolini

Overview of this book

Yocto Project is turning out to be the best integration framework for creating reliable embedded Linux projects. It has the edge over other frameworks because of its features such as less development time and improved reliability and robustness. Embedded Linux Development using Yocto Project starts with an in-depth explanation of all Yocto Project tools, to help you perform different Linux-based tasks. The book then moves on to in-depth explanations of Poky and BitBake. It also includes some practical use cases for building a Linux subsystem project using Yocto Project tools available for embedded Linux. The book also covers topics such as SDK, recipetool, and others. By the end of the book, you will have learned how to generate and run an image for real hardware boards and will have gained hands-on experience at building efficient Linux systems using Yocto Project.

Booting our baked image


The build process will likely take some time. There is a huge amount of work being done behind the scenes but it is a straightforward process.

After the build finishes, we need to deploy the generated image to the board, this is a process that varies from one board to another. We will cover the instructions for each board in the following sections.

Booting BeagleBone Black from the SD card

After the build process is over, the image will be available inside the build/tmp/deploy/images/beaglebone/ directory. There are many files, but the Texas Instrument BSP generates a ready-to-use SD card image.

The file we want to use is core-image-sato-beaglebone.wic.

Make sure you point to the right device and double check to not write in your hard disk.

In order to copy the core-image-sato image to the SD card, we should use the dd utility, as follows:

$ sudo dd if=core-image-sato-beaglebone.wic of=/dev/sdX bs=1M

After copying the content to the SD card, insert it into the SD card slot...
