  1. Ok, got it! I've moved finally to Ubuntu Focal server: make SSD from disk image make eMMC from the same disk image edit /boot/ on eMMC to my needs make SSD via USB 3.0 as root file system in kernel parameters Kernel upgrade is hard but possible.
  2. There was unneeded line in /etc/samba/smb.conf: ; socket options = TCP_NODELAY IPTOS_LOWDELAY SO_KEEPALIVE SO_RCVBUF=8192 SO_SNDBUF=8192
  3. I am observing huge difference in samba speed (both ways to/from PC on Gigabit Ethernet) with Rock Pi 4B. Earlier I had Debian and Ubuntu provided by Radxa and recently speed has gone from 115 MB/s to ~12 MB/s. I moved to Armbian which is currently available for download. Before any updates I had 115 MB/s transfer speed. When I updated to Armbian 20.08.11 Focal with Linux 5.8.15-rockchip64 the speed has go down to ~15 MB/s. The bigger change that happened was kernel upgrade. I exclude problems like: PSU (it is over enough), home network (nothing has changed) and SSD
  4. Hi All! I've recently moved to Armbian (Debian buster server) on my Rock Pi 4B - from Ubuntu provided by Radxa (some way failed upgrade). However system is booting from eMMC which has Radxa kernel and then directly to Armbian file system on SSD connected via USB 3.0. Great is that Armbian is working with Radxa kernel, which I want to change to 5.8.14-rockchip64. My question is how should I prepare /boot folder on eMMC (which is FAT file system) to boot Armbian kernel? Is there any other way (reformat eMMC for ext4@32768 sector for /boot folder) to achieve this?

    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.

    @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!

    @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?
  16. 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 ad
  17. @chwe maybe some introduction: what are these abbreviations? BSP, DT, DTS, config file, defconfig file, dtsi.
  18. 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.
  19. @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.
  20. @chwe @NicoD thank you guys, I really appreciate your effort. Board is in China so I have no possibility to move on. I'll let you know what will happen next. Maybe some Skype in night hours would be good for that, I'll let you know in a private message. I have CEST time here but willing to go over night to make the things work, as you will have time to help me. However support from seller is ready to help me giving ready solution, which I cannot accept. I was asking them for instructions, as I will reflash the board few times so their solution is not acceptable.
  21. @chwe OPi is at this moment at seller's place (China) awaiting AliExpress decision to make me a refund. If that will not work, I'll get the board from them and then I will have time to mess with it. Research that I have done tells me, that there are some files needed to run Wi-Fi and Ethernet as I expect, and they are files in the below folders: /system/etc/firmware/ /system/vendor/firmware/ I know that I've put some files in these folders and everything with Wi-Fi and Ethernet has began to work. However Wi-Fi was holding up the device after few hours of beign used
  22. @chwe I do not clearly understood what you have written here and what you are trying to achieve. Can you please elaborate more and explain what are you trying to say and achieve?
  23. @NicoD yes, you are right. I was convinced that in case of boards like RK3399 it will be the same as for RPi3B+ and previous - that the provided boards and software will be functioning properly out-of-the-box.
  24. @chwe you didn't understood what I've written here. You catch parts of my posts and complain about each one taken separately. Do understand the whole problem, not only parts of it! Then, after understanding the whole situation you are allowed to comply about the whole problem, not only parts of it. I won't be explaining further as normally thinking person would agree with me 100 times about the above and even didn't negotiate my undeniable right to get my money back. I understand that most of you here are engineers that like to mess with such hardware, but there are also rules of n
  25. @chwe My intention was not to rant the company, but warn potential buyers from making the same mistake. Yes, it is AliExpress and it is far after dispute possibility as the board I've bought about 3 months ago. I was fighting 2 months with the board and with the support to make things work as expected. Two weeks ago I've sent the board to support as they suspected hardware problem. It wasn't hardware problem. They offered me their own OS for the board - flashed by them - what destroys my expectation for this board to be applicable to my needs and violates the given 3 bullets list. There was no
