I do run a Neo3 for years 24/7 without problems. Please avoid the rage. Of course, you may have a faulty unit. At the same time, if you want to run a relatively bare board, you should be ready to learn how to do it. This looks like a connection issue before even being able to connect to the board. Can you connect to any network using the USB Ethernet adapter? Your home router, for example? Could you maybe also connect the board to your home router using Ethernet? Are you sure your UART chip supports baud 1500000? CP2102 does not, CH340G and FT232RQ do IIRC (please re-check before buying). Best Lukas

Meanwhile, I got a used device and I'll see how I setup the infrastructure for continuously maintaining the device.

Dear community, dear @Igor (as maintainer of NEO3 CSC), thanks a lot for the NEO3 support. This board ran rock solid for me approx. two years straight – much more stable than my other SBCs running Armbian (due to various reasons, no offense :)). However, the board failed to boot with "ERROR: Did not find a cmdline Flattened Device Tree". It appears that ``rk3328-nanopi-neo3-rev02.dtb`` went missing. This must have happened when upgrading the package ``linux-dtb-current-rockchip64`` from 21.08.2 to 22.02.1. As a workaround, it helps to (download the CSC image for the board again, get the file out of the image,) place the file in ``/boot`` and set ``fdtfile=../rk3328-nanopi-neo3-rev02.dtb`` in ``/boot/armbianEnv.txt`` I think it's a pity that support for this board broke, which works so well with Armbian. Any chance we can get the dtb back into the package? Cheers, Lukas
