+# Fydetab Duo
+
+The Fydetab Duo is an open source and hackable tablet by FydeOS.
+
+## Features
+
+- Display: **works**
+- GPU driver: **not working**
+- WiFi: **working**
+- Cellular: **untested**
+- SD card: **untested**
+- Sound: **untested**
+- Fingerprint: **untested**
+
+## Flashing
+
+Flashing requires `rkdeveloptool` and using it to write the new bootloader and eMMC image. To flash, press and hold the mask rom button on the board. Ensure a USB C cable is already plugged into the host computer. Run `nix build .#nixosConfigurations.<hostname>.config.hardware.rockchip.platformFirmware` and then use `rkdeveloptool ul result/rk3588_spl_loader_v1.18.113.bin`. The NixOS image can then be downloaded using `rkdeveloptool wl 0`, it is recommended to use the disko image configuration which is provided.
