Introduction circleci is a kind of Continuous Integration platform that you can build your own build pipeline. The platform provides nice ways to integrate with existing code repositories as well good features to use. It is free to use when doing some Open Source project and additional costs when use for commercial or private purposes. Before test circleci, I’ve tried another platform called travisci. But I was looking to a feature which I could use to cache some objects easily and restore them later.

A index of layers OpenEmbedded Layer is not a new tool, at least since 2015 I know that it exists. And the main purpose is to allow anyone from Yocto Project community to share their works that have been done around build new Yocto/OE layers. How to share You can submit any kind of layer, just answering a couple of questions about your new layer and send it. The awesome part is that we can search by:

A tool to check layer I was reading the Yocto Project development manual when I found a topic (Making Sure Your Layer is Compatible With Yocto Project) about how to use a tool called yocto-check-layer to perform basics checks and detect if a specific layer is compatible or needs adjustments. So I tried to run that tool against the meta-erlang layer: joaohf@porco:~/tmp/poky$ source oe-init-build-env ~/tmp/yp/build joaohf@porco:~/tmp/yp$ yocto-check-layer ~/tmp/meta-erlang INFO: Detected layers: INFO: meta-erlang: LayerType.

Introduction One of the features that I most like when using Yocto Project is the possibility to use qemu and test my custom image very early without the needed of any hardware board. All of that is integrated when using Yocto Project. See more details about how to use in Using the Quick EMUlator (QEMU). But running one qemu instance is not enough when I need to test how an application behaved in a network environment.
