this is indeed a good suggestion, I ran into such an issue myself, actually had it with Armbian and was pointed here by the Armbian devs: https://forum.armbian.com/topic/4767-powering-through-micro-usb Apparently even picking a different USB cable can make a difference. What I observed was that LEDs went off at some point during kernel startup and the board went dead. After being pointed to the above link I tried a much stronger USB power suppy (from an Acer netbook) and then it suddenly worked without any modifications to the software. > Also, although the Tinkerboard has the same pin layout as the > Raspberry Pi, unlike the Raspberry Pi the Rockchip people like to use > UART2 for the console rather than UART1.
