    Espressobin support development efforts

    Yesterday, I recorded the commands and the outputs ... -All I can see about systemd is 'processing triggers for systemd', so I'm not sure systemd is at fault directly. I can see a lot of library updates, so I would expect that this could be caused by an updated library that systemd is using. -only a simple guess, though.

    Espressobin support development efforts

    I haven't tried debian - and I do not have much time on my hand, because my server needs to be set up completely within a few days, as I'm going back home. Sadly, it seems the Ubuntu I'm running does not allow me to "reboot" without hanging, so I can't maintain much via SSH from home (because it'll cost me 6 hours to travel each way plus around $200, which I currently cannot afford). -I just thought I'd like to mention this, so that others will have fewer problems and the maintainers may know about it.

    Espressobin support development efforts

    Using Ubuntu, I just found out during the last three days that if I do a fresh install of 5.50 on my EspressoBIN and as the first thing issue apt-get update && apt-get upgrade, followed by a reboot, then the network will never come up and I'll have to log in using a serial console.

    EspressoBIN - static IP address

    After struggling with this for 3 days (this was absolutely no fun at all), I now finally came to a conclusion: apt-get update && apt-get upgrade -causes the network connection to be lost - right after a fresh installation, so my problems were completely unrelated to the modification of the interfaces.
  5. I know the MacchiatoBIN does consume more power, but it's also a way faster creature, so I accept that. -It's not easy to find anything that gets near the MacchiatoBIN (especially due to its two 10Gbit connections). As for energy consumption, the MacchiatoBIN can easlily run on solar panels with a battery bank and a backup from mains power; that's what I'm aiming for. The EspressoBIN (when the board is perfect) is good - CPU performance might not be in the top, but it is better than a fair amount of SBCs. I could wish for a better design - I especially hate that the 2.5Gbit connection to the Topaz switch was sacrificed in order to get a USB3 port (I'm way against anything USB), but also the problem with unstable boards is a concern. -AND that GlobalScale could make themselves find some cheap USB cable manufacturer that is just as unreliable as their boards does not add anything positive to the experience. I've also seen that Turris now use GlobalScale for their new board - and that scares me away from purchasing one. I'm a bit dissapointed with SBCs; it all started out good in the early Raspi days, but the imagination of the board vendors are just limited to what someone else made. I very much expected to see that native SATA would become standard on the boards (not SATA via USB) - and I also expected multiple Gbit Ethernet ports; I also expected performance to grow and the amount of RAM to grow. -But the vendors keep making boards with similar specs to previous boards - especially TV-box vendors. If I were to design a board, I'd pick one hgih-performance CPU (like the 7040 or 8040) and add a whole bunch of cheap 64-bit China chips as slaves, then inter-connect them via an on-board network switch/PHY; this would make a great compute-cluster (and build-farm). Each slave should have at least 1GB RAM (perferrably 2), one SPI-flash and one SATA connector per slave as well. Yes, it'd be fairly expensive if the board had 16 or more slaves, but I think it'd be worth it. I very much look forward to see Cortex-A76 (and even Cortex-A75) boards. I hope that the chip manufactures will add built-in support for both at least multiple 6G SATA and multiple PCIe 3.0 lanes, so we can have some "WOW"-board - yes, I'm dreaming quite a bit..
  6. Hopefully they don't provide cheap china-cables (like the broken cable shipped with my bad espessobin). How I wish EspressoBIN was made by Solid-Run instead of GlobalScale - I'm pretty sure they would have done a proper job. I'll be going for the MacchiatoBIN soon; I don't know if I'll succeed in setting up the Espresso, but at best it'll get a job as NAS server, but I don't trust it enough to make it a mail or web server.

    EspressoBIN - static IP address

    I know 'vi' will cause me additional frustrations, so I'm trying to avoid using it. -But I just re-installed ubuntu 4.17.3, then did the following as the very first thing: sudo add-apt-repository ppa:chris-lea/redis-server sudo add-apt-repository ppa:nginx/stable sudo apt-get update sudo apt-get install redis nginx sudo apt-get upgrade ... then I applied your modifications to 10-br0.network saved and rebooted. As soon as the board is in uboot, both LEDs are on (which is what they should be), but later during boot, the right-hand LED is turned off (which indicates that things won't work). I do not get any IP-address. If I log in via the terminal (now I got some portable PC with Windows and 'RealTerm', since I'm worn out moving my Mac back and forth more than 30 times), then ifconfig -a | grep addr won't show me any IPv4 address; not the static one I wanted and neither one assigned by DHCP. The router does not indicate a dynamically assigned IP address either. If I copy the original files back and reboot, the board stays off the network; it seems I can't get it online by restoring settings. -Do I need to "kick" something in anyway; eg. restart systemd, tell it to reload or flush or something like that ?
  8. That sounds very likely. -And likely that's why they're now shipping boards with a single 2GB chip instead of two 1GB chips.

    I just realized that my bogus .txt-files were causing the above, so I deleted them (even before I reached that you mentioned I should delete them). -I used head and tail to construct the configuration files, since I can't use nano in my terminal. I tried this, and I'm pretty sure that the files in systemd/network match the ones you gave me. (I checked using hexdump -C), and ensured that line-endings were 0x0a only. As far as I understand, I should not delete 10-eth0.network or 10-br0.net*, correct ? I'm willing to try a re-install, since I haven't done much customization yet - but that would unfortunately not help others getting in the same situation...

    I just recalled that before the network stopped working, I did the following: add-apt-repository for redis-server add-apt-repository for nginx apt-get update apt-get upgrade modify nginx configuration (I didn't think about mentioning it ealier, because the network was of course working until I made a reboot) -I think that the 'apt-get upgrade' might have something to do with my network no longer being brought up.

    I entered a few of the commands you listed and got the following output: (sorry, some of the lines seem to be truncated; especially parts with important information): -so zram loads (I don't think this is fatal), but it seems that there's some trouble loading modules. I noticed that resolv.conf has been changed at some point (it suddenly contained google's DNS instead of OpenDNS, which I or the router had provided earlier via DHCP). 'could not open moddep file' looks like a clue.

    Thank you so much again for your help. I've tried your setup and made a #reboot and also a hard reset for rebooting, but still no luck. Unfortunately, it seems something else must have gone wrong, because I noticed that when things worked, both the left and right LEDs on the WAN connector were lit, but currently only the left one is lit (seen from the side where you plug in the wire). Sadly I'm color-blind, so Ican be specific about the color. What should I look for in the terminal when it boots ?

    ... And suddenly it seems it doesn't work anymore (no matter how many times I reboot).
  14. That is a perfectly valid solution and I understand completely. -Fortunately it seems I have one good board, but I also have one which is flakey. Yeah, it seems some of the boards suffer from production issues; my guess would be that they're probably not soldered perfectly. (eg. I've heard some people having problems running at higher frequencies, while others have no problems). -My good board is stable, while my bad board crashes at random. GlobalScale does not reply to my emails after I told them that I had a bad board (I've always kept a nice tone). I know there's nothing wrong with the Armada; it's a high quality CPU. The RAM is likely also of good quality, but the placement of the RAM is, if you ask me, not a good choice. -I'd say that some of the PCB-design is not done very well; ESPECIALLY that idiotic Molex connector. You never supply power on a male connector (basic electric/electronic knowledge) - because they easily short circuit. You don't see the pins come out of wall-sockets either - for a good reason. -And now Odroid seem to want to copy this stupid ritual, which means I don't need to think about purchasing anything Odroid. ... By the way, I got the EspressoBIN to boot directly from the low-cost JMB321 port multiplier; the boot device just need to be connected to interface 0 (which is located in the center on most low-cost Addonics/Syba/StarTech/Deltaco/DatOptic/iocrest/whatever port multipliers). -I plan on changing to a JMB575, though - just wanted to make sure that I could use a PM before purchasing the JMB575.

    Thank you for the quick reply. Your answer did give me ideas on what to search for and I ended up with the following:, which seems to work for me - just in case others need a starting-point: $ cat 10-wan.network # see: # <https://www.freedesktop.org/software/systemd/man/systemd.network.html> [Match] Name=wan [Network] Bridge=br0 DHCP=no Address=10.0.1.2/8 Gateway=10.0.0.1 I've kept my DNS in resolv.conf (since systemd falls back to that if no DNS is specified).
