Once this was done, we went ahead in creating our own layer, in order to define our own image and its contents it terms of packages. We used it to add a graphical splashscreen, and I also extended it to include Dropbear into the build. The whole thing went quite well.
This impression is also validated by the complexity of the output directory where all the build results are. Yocto Developer Day: hands-on session starting The next part of the hands-on was around the Eclipse integration of Yocto. Thanks to an agent running into the target, Eclipse is able to push the application binary to the target and start gdbserver on it, and therefore transparently start a debugging session for the user. Then, we went ahead in trying to use HOB , which integrates into Eclipse the possibility of selecting which packages should be built and integrated into the image.
Regardless of the contents of the hands-on, I was quite interested by how it was conducted. Instead of having some written lab instructions, and having everyone following, alone, those lab instructions, the instructor was simply demoing the various steps to be done on the video-projector screen, which we simply had to replicate.
It makes the session quite interactive, with of course the drawback that everyone needs to progress at the same pace. All in all, this Yocto Developer Day was interesting, and I hope to find some time soon to experiment further with Yocto.
A package recipe can modify the shared state caching to a task; for example, to always force a rebuild by marking it as nostamp. By default, the build system will use a shared state cache directory called sstate-cache on your build directory to store the cached data.
The cached data is stored in directories named with the first two characters of the hash. Inside, the filenames contain the whole task checksum, so the cache validity can be ascertained just by looking at the filename. The build process set scene tasks will evaluate the cached data and use it to accelerate the build if valid.
When you want to start a build from a clean state, you need to remove both the sstatecache directory and the tmp directory.
You can also instruct BitBake to ignore the shared state cache by using the --no-setscene argument when running it. It's a good practice to keep backups of clean shared state caches for example, from a build server , which can be used in case of shared state cache corruption. There's more Sharing a shared state cache is possible; however, it needs to be approached with care.
Not all changes are detected by the shared state cache implementation, and when this happens, some or all of the cache needs to be invalidated. This can cause problems when the state cache is being shared.
The recommendation in this case depends on the use case. Developers working on Yocto metadata should keep the shared state cache as default, separated per project. However, validation and testing engineers, kernel and bootloader developers, and application developers would probably benefit from a well-maintained shared state cache.
Setting up a package feed An embedded system project seldom has the need to introduce changes to the Yocto build system. Find Ebooks and Videos by Technology Android. Packt Hub Technology news, analysis, and tutorials from Packt. Insights Tutorials.
