Follow the same steps as for FHD/1080p, but for UHD/2160p (3480x2160). I am only able to get 4K@30Hz working: $ cvt 3840 2160 30 # 3840x2160 29.98 Hz (CVT) hsync: 65.96 kHz; pclk: 338.75 MHz Modeline "3840x2160_30.00" 338.75 3840 4080 4488 5136 2160 2163 2168 2200 -hsync +vsync $ sudo xrandr --newmode "3840x2160_30.00" 338.75 3840 4080 4488 5136 2160 2163 2168 2200 -hsync +vsync $ sudo xrandr --addmode HDMI-1 "3840x2160_30.00" $ sudo xrandr --output HDMI-1 --mode "3840x2160_30.00" Once you have this working, you can make this permanent by creating an xorg config file with your modelines. Here is my /etc/X11/xorg.conf.d/10-monitor.conf: Section "Monitor" Identifier "HDMI-1" Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync Modeline "3840x2160_30.00" 338.75 3840 4080 4488 5136 2160 2163 2168 2200 -hsync +vsync Option "PreferredMode" "3840x2160_30.00" EndSection

This boots for me - I've enabled verbosity=7 in /boot/armbianEnv.txt and can see it booting the kernel, it sits for about 30 seconds at the following line: systemd-journald[385]: Received request to flush runtime journal from PID 1 ...but eventually does boot to the login prompt. USB3 seems to work on this build, but still no luck on the ethernet side of things. Out of interest, I plugged in an external USB3 ethernet adapter and that works perfectly.

Thanks again so much for all your work, @krachlatte! I have tried setting a static IP, as well as using ethtool to set the link speed to both 100 and 1000 full duplex, but no luck. The static IP is applied, but the device is still not able to reach the network. Running the udevadm command does not appear to generate anything - the /etc/udev/rules.d/70-persistent-net.rules file is still not present afterwards. Yes, I have the 8GB eMMC version, and this appears to be detected in this build (mmcblk1):

The new image boots, but again no network or HDMI output. This time the local eMMC (/dev/mmcblk1) appears to be detected. Boot log: ifconfig: ethtool -S eth0: ethtool eth0: /etc/udev/rules.d/70-persistent-net.rules does not exist. lsmod: lspci -v: dmesg:

This is now booting for me, but without network or HDMI output. There is quite a long delay where it just sits at 'Starting kernel ...', but eventually the login prompt appears This is the serial boot log:

Okay, managed to find a USB-TTL converter . This is the output (it just hangs at that point): U-Boot SPL 2018.09-rc1-armbian (Feb 11 2019 - 08:44:18 +0100) DRAM: 2048 MiB Trying to boot from MMC1 NOTICE: BL31: v2.0(debug):32bcba0 NOTICE: BL31: Built : 23:07:19, Feb 8 2019 NOTICE: BL31: Detected Allwinner H6 SoC (1728) NOTICE: BL31: Found U-Boot DTB at 0xc070e20, model: OrangePi 3 INFO: ARM GICv2 driver initialized NOTICE: PMIC: Probing AXP805 NOTICE: PMIC: AXP805 detected INFO: BL31: Platform setup done INFO: BL31: Initializing runtime services INFO: BL31: cortex_a53: CPU workaround for 855873 was applied INFO: BL31: Preparing for EL3 exit to normal world INFO: Entry point address = 0x4a000000 INFO: SPSR = 0x3c9 I get the same results as gnjack - the OrangePi One Plus image boots (and correctly outputs over HDMI), but has no networking.

Still not booting for me. Sorry but I don't have a serial interface here with me so I can't provide any logs at this stage .

Hi krachlatte, I have downloaded and flashed your base image and it does not boot for me - no LED activity at all (the 'official' images from http://www.orangepi.org/downloadresources/ boot just fine).
