You can build a debian package from SWUpdate sources (check in debian directory and in the documentation) and you can add it to your rootfs. > Considering the situation > described here, is there any tutorial/web/anything that could be used as > a guide (for dummies) to suitable generate the images using Yocto? Any > help will be greatly welcome. Image generation is supported via the additional meta-swupdate layer, but this works until you are in a OE environment. Outside this, you have to generate images on your own.
