I just started learning Yocto a few weeks ago, and just shipped my first embedded image. Here are a couple of learnings and thoughts: 1. Start with an empty image and build your way up. There can be some cross-effects between packages depending on what you exactly do, it's a lot easier to debug if you go step by step. The base image recipes are all listed in the documentation, start with one of them.[1] 2. Lean into Bitbake and the whole thing. The more you try to fight it, the more it fights back. I liked this guide as a starting point to get a feel for it.[2] 3. Find a way to quickly iterate on your images. Nothing worse than losing your train of thought! Since I wanted to include update functionality I added swupdate, which integrates reasonably well with Yocto[3] - although the documentation is a bit difficult to read at times. But being able to simply push an update through WiFi is really, really nice. 4. If you do some lower-level stuff you'll inevitably need to create configuration fragments. This process was REALLY opaque to me. Say you want to set build options for U-Boot - you'll have to: 1) run `bitbake -c menuconfig u-boot` to open the config menu; 2) when closing the menu, you save the configuration in the default location; 3) then you run `bitbake -c diffconfig u-boot` to generate a config fragment; 4) you copy the config fragment into your recipe-append-folder and add it to the SRC_URI variable; 5) you run `bitbake -c clean u-boot`. When U-Boot is built the next time it will apply your configuration fragment to the build process. These were the most important things that came to mind. Hope they help, and good luck on your journey! :) [1] https://docs.yoctoproject.org/ref-manual/images.html https://docs.yoctoproject.org/ref-manual/images.html [2] https://a4z.gitlab.io/docs/BitBake/guide.html https://a4z.gitlab.io/docs/BitBake/guide.html [3] https://sbabic.github.io/swupdate/building-with-yocto.html https://sbabic.github.io/swupdate/building-with-yocto.html
