Summary
rkdebian is a build system that produces a bootable Debian 12 Bookworm image for the Doogee U10 tablet powered by the RK3562 SoC. The pre‑release image (May 14 2026) supports full touchscreen, Wi‑Fi, Bluetooth, 3D acceleration, and NPU inference via the RKLLM stack, enabling local LLM execution with models like Qwen3‑0.6B. The image includes default applications such as Firefox ESR, Chromium, FreeTube, Plasma, and a suite of command‑line tools. Build scripts support U‑Boot, kernel, rootfs, and image generation, with options for GPU stack, display server, and CPU governor.
Benchmark results show Qwen3‑0.6B generating 4.92 tok/s on the RK3562, outperforming Qwen2.5‑1.5B. The build system also provides support for delimited file I/O, comparison tolerance, and a comprehensive test suite. Users can flash the image to an SD card and boot the tablet into a full Linux environment, with the ability to revert to Android by removing the SD card.
rkdebian offers a practical solution for developers and enthusiasts who want a Linux experience on the Doogee U10 without unlocking the bootloader or modifying internal storage.
