Yea, for sure, it might sound very loose compared to something like a microcontroller. But embedded is very broad. Some of our devices run Chromium, for example :-)
Hi! We either use Yocto recipes for 'regular' embedded (meta-imx and meta-browser are good starting points) but we also apply nxp-specific patches on top of Chromium from Debian and use the usual standard tooling like `sbuild` to run it inside the containers (renting out AWS arm64 instances in this case, because building Chromium requires a metric ton of cores and memory. Cross-building is quite challenging, so I wouldn't recommend that).
