Latest Engineering Guides
All guides →Android Kiosk Mode on Rockchip Devices (Lock Task, Device Owner, Boot to App)
Turn a Rockchip Android board into a single-purpose kiosk: device-owner provisioning, lock-task mode, booting straight into your app, and what to bake into the ROM instead.
Build Mainline U-Boot for Rockchip (RK3588, RK3568, RK3399)
Build a mainline U-Boot image with TF-A and the Rockchip DDR blob, then write it to SD, eMMC or SPI flash.
Build the Rockchip Linux Kernel (Vendor BSP and Mainline)
Cross-compile a Rockchip kernel on an x86 host, install the Image, DTB and modules, and know when to choose the vendor BSP or mainline.
Configure GPIO on Rockchip: Pin Numbering, Device Tree and libgpiod
Convert GPIO3_B5-style names to Linux line numbers, drive pins with libgpiod, and describe them properly in the device tree with pinctrl and overlays.
Convert YOLO to RKNN and Run It on the RK3588 NPU
Export YOLO to ONNX, quantise and convert it to .rknn with RKNN-Toolkit2 on an x86 host, then run it on the board with RKNN-Toolkit-Lite2, using all three RK3588 NPU cores.
Flash Any Rockchip Board with rkdeveloptool (Linux & macOS)
Build rkdeveloptool from source, set up udev permissions, and flash raw images, partitions and SPI flash on Rockchip boards.
