Hi, I've just tested my pcDuino3 and pcDuino3nano boards. I compiled Ubuntu 18.04, Dev kernel as headless and desktop for nano and non-nano) with vagrant. Interestingly, the nano "flavour" seems to work fine on both boards (4.20.7-sunxi Kernel , HDMI, USB, Nework on pcDunino nano (except for the not-working network on the pcDuino3 board, obviously). But I cannot boot the non-nano version on either board. I connected a serial output and it hangs at: U-Boot 2018.11-armbian (Feb 07 2019 - 13:21:03 +0000) Allwinner Technology CPU: Allwinner A20 (SUN7I) Model: LinkSprite pcDuino3 I2C: ready DRAM: 1 GiB MMC: Tried different cards, different PSUs, no change.

I can confirm the unstable behaviour described by denox for pcDuino 3 and pcDuino 3 nano with Armbian 5.37 / 5.38 as well. The same goes for the dev kernel 4.15 RC9. Maximum uptime was 2 days, but 5 to 20 hours was more common. My installation is pretty basic: Armbian Xenial, Desktop disabled, mariaDB, Apache2, owncloud. Last stable kernel seems to be 4.13.16 (Armbian 5.35) for both boards: uptime 6 days and counting.
