    Rock PI 4

    I bought here https://pishop.at/index.php/single-board-computer/rock-pi-4-model-b-4gb-detail with overall price (with shipment) €114.78 (504.44 PLN). I've seen the same model €105 from Spain without shipment...

    @Dante4 unfortunately there are some countries which they are not shipping to. Poland is one of them.

    @NicoD I will need to order heatsink. For now it is just a test board. I'll try not to heat it too much.

    My Rock Pi 4 B 4GB just arrived. Unluckily I don't have PSU for it yet.

    Rock PI 4

    @martinayotte I am not asking about Armbian. I am asking about the mentioned OSes. I have Armbian on armv7l and it is 32-bit. At least provided binaries are 32-bit. I ask about bitness of the provided OSes for Rock Pi 4. There is no Armbian for this board.

    @martinayotte I am not asking for CPU bitness. I am asking if these OSes images are 64-bit!

    Rock PI 4

    @hipboi I already have this one. I was asking if these are 64-bit or 32-bit...

    Thank you for the links! Are these 64-bit Debian/Ubuntu?

    @mboehmer Where did you get Debian for this board?

    RK3399 Orange Pi

    Well, guys, I am just letting you know that: I will get my money back for Orange Pi RK3399 or just sell it as it does not meet my standards, that is it has USB 2.0 instead of USB 3.0 and following the unresolved by support problems (Wi-Fi, Ethernet) I am rejecting this board as it does not comply with my needs I was interested in Firefly RK3399 which has no bugs like OPi RK3399 but will not currently invest money in it, however it seems like a great board Move my RPi 3 B+ in-house hosting to Virtual Private Server as I need more performance power So this is how ends my adventure with single-board computers. From now on I will be using them just for testing purposes. Anyway thank you all very much for help and comments. I appreciate your effort and wish you good luck in your battles with these quite fun parts of electronics.

    @chwe maybe some introduction: what are these abbreviations? BSP, DT, DTS, config file, defconfig file, dtsi.

    RK3399 Orange Pi

    Well, not 90 days, but 30. Yes, for future I need to test the hardware in a shorter period of time and send it ASAP to get refund. In this case seller should act like a good EU company and just make a refund, not making any problems as they just did.

    RK3399 Orange Pi

    @Igor that is another one reason to make the seller refund me. Nobody needs a hardware, when there is no proper software for it. If company wants to make hardware omitting software, then it should take responsibility for its actions. No more theory needed for that.
