Running Armbian on RK3318/RK3328 TV box boards involves addressing several low-level integration challenges across the bootloader, kernel, and device tree layers. The boot chain typically follows Rockchip’s MaskROM → SPL → U-Boot → kernel path, so ensuring a compatible U-Boot build with correct FIP and device tree selection is critical for stable booting from eMMC, SD, or USB. Kernel support (preferably ≥5.15 or 6.x) should include Rockchip DRM/KMS for HDMI, MPP/V4L2 for hardware video decoding, and panfrost or Mali GPU drivers for OpenGL acceleration. Device trees must accurately define clocks, pinctrl, power domains, Ethernet PHY, Wi-Fi (usually SDIO or USB), regulators, and thermal zones to avoid boot or stability issues. HDMI audio is handled through ASoC/DRM audio paths, while IR remotes, LEDs, and UART consoles require proper GPIO and input bindings. Armbian-specific integration demands a clean /boot/armbianEnv.txt, proper overlays, and firmware blobs for Wi-Fi/BT and GPU if proprietary. Finally, validating DRM, VPU, and network functionality through serial logs, dmesg, and v4l2-ctl ensures the image reaches production-grade stability.
