    NicoD, your YouTube videos are why I chose Armbian.  I think the Armbian tools are awesome, and I'm grateful to those who created and maintain it.

    Are the existing real time classes in the CPU and I/O schedulers not enough in the standard kernel?
     
    Substantial portions of the RT patch set were merged back in kernel 2.6, and we're substantially past that point now.

    lanefu reacted to binarym in NanoPi R2S: lan0 goes offline with high traffic   
    Hi all !
     
    I faced the same issue with my Nano PI R2S : even with nightly builds, the r8152 randomly hanged and lan0 disappeared.
    I built a minimal armbian buster and revert the driver to previous 1.11 version.
    I also manually modified my /etc/udev/rules.d/70-rename-lan.rules with the following content:
     
    SUBSYSTEM=="net", ACTION=="add", DRIVERS=="rk_gmac-dwmac", KERNEL=="eth0", NAME="wan0" SUBSYSTEM=="net", ACTION=="add", DRIVERS=="r8152", NAME="lan0", RUN+="/usr/sbin/ethtool -K lan0 tx off rx off"  
    It manages correctly my home fiber with ~600Mbps for DL and ~300Mbps for UL.
    Under heavy charge, i didn't experiment lan0 freeze for at least 1h (previously, it froze every 10 minutes).
     
    I guess 2.5Gbps support is lost but:
    For people with 1Gbps network, it's enought. I have serious doubt regarding the ability of R2S to route 2.5Gbps traffic ;-)  
    For people interested and who do not have time/skill/machine for compilation you can download the image here (~950MB uncompressed) : https://drive.google.com/file/d/1RRvmObBDi58TRTnZN661PL0PYFRbAi0_/view?usp=sharing

    Here's a package comparison I did today of fresh installs (yesterday) of Armbian and Debian. Unfortunately, I forgot to do an update/upgrade of Armbian before listing the packages, so Armbian may appear to be slightly out of date compared to Debian, but the comparison took me too long to repeat it just for that update.

    lanefu reacted to hexdump in Jetson Nano   
    just a little update: i got the open source nouveau gpu driver working with the mainline kernel finally by using a self compiled xorg server from the latest sources (required - see: https://gitlab.freedesktop.org/mesa/mesa/-/issues/3505), a self compiled mesa 21.0.1 (not sure if this is really required) and the "nouveau.modeset=1" kernel cmdline parameter - what is nice is that it is opengl 4.3
     
    so far the good part, the bad part is that it is extremely slow (glmark2 score of 68) as it is clocked at the lowest gpu frequency by default and trying to increase the gpu frequency via /sys/kernel/debug/dri/128/pstate seems to make the system quite unstable or quickly hangs it (maybe my power supply - 5.1v/3a - is not powerful enough?)
     
    i'm also able to run a wayfire wayland session using the nouveau gpu driver, but it shows quite a few graphical artifacts when scrolling in a terminal or doing other activities - glmark2 score here is 83, but its also for lima or panfrost higher in wayland/wayfire than in xorg/xfce
     
    all in all it looks like the quality of the open source nouveau driver on the jetson nano (maybe even in general?) is not really the best and as it looks to me far behind the quality of the lima and panfrost open source drivers for the mali gpus in other socs

    lanefu reacted to Palaretri in Can't see eMMC on BPI-P2   
    Hi all,
    I'm working with a BPI-P2 board.
    I installed the last Armbian version for BPI-M2 as the two boards are basically the same except the RJ45 connector and the eMMC.
     
    I installed it on an SD card, and everythig worked perfectly.
     
    Now I need to put the OS on the eMMC and then completely remove the SD card, but I'm struggling.
     
    The default Armbian for BPI-M2 is not intended to support eMMC, so I'm not surprised that with this version the eMMC dosn't show up.
     
    So I tried to modify the dtb and enable the eMMC nodes, and then reboot.
    Here the changes I made:
     
    mmc@1c10000 {
                reg = < 0x1c10000 0x1000 >;
                pinctrl-names = "default";
                pinctrl-0 = < 0x0d >;
                resets = < 0x03 0x08 >;
                reset-names = "ahb";
                interrupts = < 0x00 0x3d 0x04 >;
                status = "okay";
                #address-cells = < 0x01 >;
                #size-cells = < 0x00 >;
                compatible = "allwinner,sun7i-a20-mmc";
                clocks = < 0x03 0x17 0x03 0x4a 0x03 0x4c 0x03 0x4b >;
                clock-names = "ahb\0mmc\0output\0sample";
                vmmc-supply = < 0x0b >;
                vqmmc-supply = < 0x0b >;
                mmc-pwrseq = < 0x0e >;
                bus-width = < 0x04 >;
                non-removable;
                phandle = < 0x44 >;
     
                mmc2-8bit-pins {
                    pins = "PC5\0PC6\0PC8\0PC9\0PC10\0PC11\0PC12\0PC13\0PC14\0PC15\0PC16";
                    function = "mmc2";
                    drive-strength = < 0x1e >;
                    bias-pull-up;

                    phandle = < 0x54 >;
                };
     
     
    Sadly this wasn't enought, and I still can't see the eMMC.
     
    I read a lot of threads, but I've not been able to find a solution.
    I guess that I have some problems with the uBoot or with the drivers not present in the kernel.
     
    I'm quite new to Linux, and I've never recompiled a kernel or a uBoot.
     
    Please, can someone help me?
     
    Thank you!

    lanefu reacted to zimme in Odroid C2 : no eth0 with latest image   
    I just wanted to write an update on this issue as I've ran into it also, but I figured out a way to make it work.

    My board was in a "broken" state where the network card wasn't working with any of the latest versions of Armbian using a newer u-boot like 21.04-rc3.
    I compiled my own versions to test the latest edge and using u-boot 21.04-rc4, etc. but nothing worked.

    I got it working by accident and I wasn't sure how but then I flashed the sdcard again with a different version and got into the broken state again.

    This lead me down an evening of frantically testing a bunch of things and that's when I discovered a way to get out of this broken state with a newer
    version of u-boot (21.04-rc or later).

    Grab the latest stable image which uses u-boot 21.04-rc3, flash it to an sdcard and boot the board and wait 5 min or something to make sure the board has actually booted (I'm running headless so no monitor connected).
    Once you're sure the board has booted, unplug the network cable and reconnect it. Then wait for a couple of minutes and then power cycle the board and that made the network card work again for me every time I
    got into this broken state.

    Hope it helps someone else and if not I guess that something else made my network card work again.

    lanefu reacted to vmiceli in Defaults for Ethernet coalesce?   
    Hello folks,
     
    I have completed my Armbian NTP server based on the wonderful little NanoPi Neo3. However something bothers me a bit, i.e. how much delay or latency is in eth0 (It is a 1Gbs port).
    By checking the default eth0 settings (ethtool -c eth0) I have the parameters below. In particular rx-usec = 327usec means that when a packet is received, the IRQ to alert the CPU can be delayed up to 327usec. With these settings on the nanopi (NTP server) I get about 1msec delay on the NTP client (Windows PC). By cutting the rx-usecs to 35 usecs I get a delay on the client of  about 450usec, so a massive improvement and 30% faster than rpi 4.
     
    At the moment, in order to change this parameter after boot, I have the two lines below into /etc/rc.local, the delay is needed as the command may be issued before eth0 is ready to accept it (I found this the hard way):
    sleep 10 sudo ethtool -C eth0 rx-usecs 35  
    The question: Is there a place where those eth0 defaults are saved? If there is a config file somewhere or even in the Kernel (I can re-build it) I could change them to a new default and avoid the rc.local hassle and delay.  I guess I like a leaner approach :-)
     
    Thanks!
     
    Enzo

    Foreward: Not sure if this better fits in board bring up, but I can't post there, so feel free to move if appropriate.
     
    I'm looking into the feasibility of using the Armbian build system to generate OS images for the Avnet MicroZed board. This board is based on the Xilinx Zynq 7000 platform, which is a SoC made up of a dual core 500 MHz CPU, and a Artix-7 generation FPGA. The CPU is nothing to write home about, but the FPGA opens up an interesting array of possibilities. Just in case you need an ARM board with 100+ GPIO, over two dozen serial ports, or your own function generator. Really, you're limited only by pin count, FPGA fabric usage, and what you can manage in Vivado. Xilinx also has an active presence on GitHub, and branches for kernels as new as 5.12, so sees active support.
     
    The big rub, is that the Zynq CPU boots off a VFAT partition, that contains a file named "boot.bin". This boot file combines the first stage bootloader (FSBL) and u-boot, and needs to execute a C application to assemble this file. The application is recently open sourced, and previously existing open source software also exists. But I'm not sure how best to integrate that with the build system, or identify that the platform u-boot package depends on this extra package.

    My understanding is that we are still building release images from master branch and the removal of this line from targets.conf:
    -rockpi-4b legacy focal cli stable yes means that focal legacy image for rockpi-4b will not be built.
    Lack of focal legacy image among 20.02.3 release images (built after the referred commit was merged) seems to corroborate that theory ;-)

    OMV Version 5.6.2-1 (Usul)
     
    So I would say that OMV is not the culprit out of the box. The system works fine but it always depends on what kind of plugins you are using etc. So far I have no docker installed here but I certainly will do that again. I do recommend the OMV Backup Plugin so I can boot from the latest stable release via SDcard if I mess up with something. That's also nice.
