Hi Gaetano, I'd be suprised if Buster did work with such a newer kernel. dwc2 is Pi specific and will not work on Allwinner/Sunxi hardware. The OTG usb controller is completely different, please see the wiki: https://linux-sunxi.org/USB_OTG_Controller_Register_Guide Overlays will only load overlays found in /boot/dtb/overlay/ while user defined ones exist in /boot/overlay-user/ As expected otg is the default mode, firstly those warnings are normal when decompiling the dtb back dts as not everything gets translated back. For small modifications you can use sudo armbian-add-overlay which compiles the overlay and places it within /boot/overlay-user This problem seems to occur every now and again in some kernel releases, please refer to here: for a solution. I would refer back to the board schematic before adjusting the dts. On the Pcduino2 and Pcduino3, the OTG micro USB passes through a small resistor rather than a fuse so causes a slight voltage drop. Just make sure that you have a good quality lead that ensures the board gets 5V but slightly over is better. sudo armbianmonitor -m Stop monitoring using [ctrl]-[c] Time CPU load %cpu %sys %usr %nice %io %irq Tcpu PMIC DC-IN C.St. 22:19:42 960 MHz 0.39 14% 9% 5% 0% 0% 0% 33.7 °C 30.2 °C 5.34V 0/6^C Best of luck Ryzer

I see there is a "UART" on the front board image, but I guess it does not work for you. Check the sorroundings for possibile missing resistors, sometimes they remove some small SMD resistors to make the UART non-functional. Also note that you must use an adapter that is capable of 1.5Mbps; not all of them can reach such baud rates (AFAIR pl2303 can't, but CH301 should work)

Disclaimer: I know it's not a good idea XD Is it possible somehow to upgrade the prebuilt image Armbian 12/OpenMediaVault 7 to Armbian 13/OpenMediaVault 8? Is there a guide?
