We do appreciate your constructive feedback to developers. What are testing images (WIP)? ¶ĭo not use testing or edge images in a productive environment. If in your specific case something does not work well, you are always free to try an image with an other kernel included. The level of kernel support however always depends on the board family. Untested, unstable, can break at any time, for experienced users only. edge is as the name implies cutting-edge and usually following the latest mainline kernel or 3rd party development branch.current is usually following current mainline LTS kernel and considered fully supported and can bring up features video acceleration for example.Use if either current is not available or something does not work well. legacy is either a vendor provided kernel or an old LTS mainline kernel.Some boards have different options due to their hardware specialities - router or IoT boards. Other (unsupported) builds may also be available (like Debian Bullseye/Sid or Ubuntu Lunar/Mantic).


The download for each image consists of three separate files:įor each board we usually provide various image types: a reliable SD card (see below “How to prepare a SD card?”).a proper power supply according to the board manufacturer requirements (basic usage example: 5V/2A with DC Jack barrel or thick USB cable).
