Revealed earlier this year as a Raspberry Pi rival, Google’s Coral Dev Board single-board computer (SBC) and System-on-Module (SoM) just received a much-improved, more stable and up-to-date Mendel Linux OS, which is based on the latest Debian GNU/Linux 10 “Buster” operating system series and ships with Linux kernel 4.14 LTS, Python 3.7, and U-Boot 2017.03.3, as well as upgraded GStreamer, OpenCV, and OpenCL components. Google urges all Coral SBC users to upgrade their Dev Board or SoM to Mendel Linux 4.0 “Day” as soon as possible by following their internal documentation on how to flash a new system image, which is currently only possible on GNU/Linux and macOS platforms. However, before flashing a new image, users should keep in mind that all system and local data will be deleted during the installation process.
