I flashed the last recent Armbian Bionic (desktop mainline kernel 4.14.y) dated on 22.08.2018. Most of the device tree is the same. One thing I noticed is SPI (fetched from the loaded device tree): Armbian spi@c005b000 { pinctrl-names = "default"; #address-cells = <0x1>; num-cs = <0x1>; pinctrl-0 = <0x49>; clock-names = "spi", "spi_busclk0"; resets = <0x12 0x2c 0x12 0x2d>; interrupts = <0x0 0xc 0x0>; clocks = <0x48 0x48>; samsung,spi-src-clk = <0x0>; #size-cells = <0x0>; dma-names = "tx", "rx"; compatible = "nexell,s5p6818-spi"; status = "disable"; reg = <0xc005b000 0x100>; dmas = <0x39 0x6 0x0 0x39 0x7 0x0>; reset-names = "pre-reset", "spi-reset"; }; FriendlyARM spi@c005b000 { reg = <0xc005b000 0x100>; dmas = <0x3a 0x6 0x0 0x3a 0x7 0x0>; interrupts = <0x0 0xc 0x0>; pinctrl-0 = <0x49>; compatible = "nexell,s5p6818-spi"; cs-gpios = <0x29 0x1e 0x0>; clock-names = "spi", "spi_busclk0"; reset-names = "pre-reset", "spi-reset"; clocks = <0x48 0x48>; num-cs = <0x1>; resets = <0x11 0x2c 0x11 0x2d>; status = "okay"; #address-cells = <0x1>; samsung,spi-src-clk = <0x0>; #size-cells = <0x0>; dma-names = "tx", "rx"; pinctrl-names = "default"; spidev@0 { reg = <0x0>; compatible = "linux,spidev"; spi-max-frequency = <0x989680>; status = "okay"; controller-data { samsung,spi-feedback-delay = <0x0>; }; }; fbtft@0 { fps = <0x21>; reg = <0x0>; debug = <0x0>; compatible = "sitronix,st7789v"; reset-gpios = <0x4b 0x8 0x0>; spi-max-frequency = <0x2faf080>; dc-gpios = <0x4a 0x1c 0x0>; rotate = <0x5a>; status = "disabled"; buswidth = <0x8>; controller-data { samsung,spi-feedback-delay = <0x0>; }; }; }; Because NanoPi Fire3 is not supported from Armbian, how can I still contribute? https://github.com/armbian/linux is only for sun8i / rockchip CPUs. Should I just clone https://github.com/armbian/build and the script knows how to fetch the correct kernel?

I made a preview of a NanoPi Fire3 CAD model: https://grabcad.com/library/nanopi-fire3-1 I hope someone can design an enclosure from the Fire3 model.
