    my experience. H96 board with rk3399.
    Take the distro from Orangepi site, dd it on the SD-card. insert and turn on power. It is running.
    Later, the kernel changed (recompiled by me) to
    root@localhost:~# uname -a
    Linux localhost 4.4.114 #11 SMP Mon Mar 12 08:46:26 UTC 2018 aarch64 aarch64 aarch64 GNU/Linux

    The problem is with dtb file: partially it works.
    USB2 is ok, HDMI is ok, Ethernet is ok.
    But:
    [ 0.809301] cdn-dp fec00000.dp: Direct firmware load for rockchip/dptx.bin failed with error -2
    (file dptx.bin present)

    So, USB3 (and DP) is off (both type-C and normal USB3 blue socket; it works in Android on the same board; dtb file taken is the same as in Android distro).
    Also, I cannot check AV output and ALSA shows only SPDIF, that has no controls.
    I think the only need is any correct dtb file to work with the board.

    I have bought Orangepi RK3399 via aliexpress. On orangepi www site are img's files of linux dabian 9 and ubuntu 16.04. But this file not full system img that can be flash via RK_Android_Toll. They are precompiled rootfs files. According to the manual i have downloaded Linux4.4_SDK and build kernel ./build/mk-kernel.sh rk3399-orangepi. I also build uboot ./build/mk-uboot.sh rk3399-orangepi. i used existed roofs file debian9 and compile img system file ./build/mk-image.sh -c rk3399 -t system -s 4000 -r out/debian9.img. Then i entered hardware to the maskroom mode and ./build/flash_tool.sh-c rk3399 -p system -i out/system.img. Finally i flashed system.img to the emmc memory. But when i plug in device i have black screen. Nothing is booting. Others people have the same problem. Something must be wrong with the precompiled roofts files or Linux4.4 SDK. People ask on orangepi forum about this problem but forums' admin say only "do things according to the manual". I must say manual is not clear. No other support from orangepi. Do you plan to build armbian for orangepi RK3399 device?
