Yocto, RockPi and SBOMs: Building modern embedded Linux images

21 FEB • 2025 8 minutes TLDR: I wanted to generate an up-to-date disk image for a Rock Pi 4 using Yocto that included CUPS and Docker to both get a better understanding of Yocto and test the new SBOM generation feature. As with many single-board computers (SBCs) from China, the issue often isn’t the board itself but rather the software. RockPi from Radxa is no exception. If you go and download the latest disk images for this board, you will notice that they are all end-of-life (EoL). However, these boards are still great and work very well for many applications. This should be top of mind if you are building a product that uses any of these devices. I wanted to use one of the RockPi 4 boards I had for a simple print server. It’s not a customer product, of course, but let’s assume it was. Since it has the option to add eMMC storage, I find it more reliable than Raspberry Pi (I know the Raspberry Pi 5 allows for proper storage). However, given that I neither trust the Radxa disk image ... Read full article.
