    sfx2000 got a reaction from NicoD in Poll : What board images do you trust to use?   
    Depends on the vendor - some do a better job than others...
     
    And there, depends on the SoC's being used.
     
    Not naming names there to avoid slanting the poll...

    Hmm... actually yes - is the role of Armbian to teach users about Linux? Probably not, IMHO, they're better served by the Pi Folks - Raspbian is good training wheels for folks dipping their toes into Linux
     
     
    The average Armbian user is not a paying customer - there are no Service Level Agreements dictating that any bug of a defined severity level must be fixed within a specific timeframe.
     
    So yes - just ignore it for the most part, step in if is sounds fairly interesting - sounds a bit mean spirited perhaps, but generally folks will step in to help out, and if it's really a bug that is directly traceable back to Armbian code - then if it pops up enough, fix it directly, or delegate it to someone who is maintaining it (better to delegate, as that person knows the code likely better).
     
    So if someone has problematic hardware - "my whoflungpI Zero2W with the built in XYZ WiFi adapter doesn't work" - well, it might be crap hardware, and in the sub-$50USD field of hacker boards and TV boxes, there's a fair amount of crap - can't fix bad hardware, and there, someone will tell them, use something that does work.

    Always hard to mask HW w/SW, but that's always been true - and sometimes it's upstream at a chip level errata.
     
    Don't sell the community here short - there are plenty of active contributors here that have specific skills, and some do this kind of work in their day jobs - but it is a valid point that it's unpaid, volunteer time, and resources are never enough.
     
    The fact that Armbian is on the radar as a serious distro is a good sign of the quality of the community.

    16MB SPI NOR is a good choice, not just for uBoot, but one could put an entire operating system in there (openwrt for example)
     
     
    I agree - @chwe - solder down is going to offer benefit of cost and board space - 16GB is plenty of space considering the other connectivity.

    QC/Atheros IPQ4019 - more relevant here for the ARM folks - IPQ4019 is a quad core Cortex-A7@800MHz
     
    Buys us GigE on WAN/LAN ports, along with ATH10K for dual-band 802.11 a/b/g/n/AC Wave2 along with USB3.0 for the USB user facing port.
     
    BOM cost is higher, as it manf. costs with more layers, and more power needs - and numbers there do not make sense for an affordable board for this community - $100 GOGS there...

    Quick update on DingleBerry Pi...
     
    Schematics - done - It's essentially a respin of the QC/Atheros reference design into a Pi board form factor.
    Layout/Gerbers - done - 4 layer board, single sided - nice to have a friend with an Orcad license from Cadence.
     
    Specifics
    MIPS24kc @ 650Mhz - big endian 802.11n - ATH9K driver - 2*2:2 for 300Mbps at 2.4GHz (wide channels) - PCB trace antennas Two 100Base-2 Ethernet - WAN dedicated port, LAN on switched port One USB-A for peripherals MicroUSB for Power/Console 32MB SPI-NOR flash - uboot and OS 128MB SPI-NAND flash - extending FS for application and user space 64MB DDR2 RAM SW - OpenWRT Master on the ATH79 target Bootloader - uboot with Pepe2K mods (web server fail-safe)  
    The 4351 does have PCIe, but I've decided not to implement
     
    Performance Targets:
    Reference board is good for 100Mbps WiFi and NAT LAN/WAN performance so fairly balanced there. Power - 5V5DC, 1000ma for PS - right now with everything active on reference design, we're around 850ma at max load.  
    BOM is reasonable, COGS says we're around $50USD to cover the NRE and breakeven with 1K boards with kits (box, cables, boards, ac adapter)
     
    I will not build/ship at a loss... So the next step before doing the engineering sample boards it to gauge the potential market interest.

    Hi guys,
     
    I guess some might have heard that we (Kobol Team) were spinning a new project to succeed to Helios4. Here it is... Helios64
     

     
     
    We didn't have to look too far for the board name since in essence the goal was to redesign from scratch Helios4 with a 64-bit SoC and try to improve every key features that made Helios4 a very targeted board for NAS setup.
     
    Right now we are at the prototyping test phase, hopefully in a 2 month time will have dozen of Eval boards to send around for evaluation and review... and if all goes well first batch should be available for order in Feb / March 2020.
     
    Happy to answer any question :-)

    sfx2000 got a reaction from gounthar in SBC recommendations for a wireless router   
    EspressoBIN is ok - has it's limitations, but living within them, it's good - good enough that pfSense/NetGate built a FreeBSD routing distro on it as a commercial product.
     
    EspressoBIN is interesting for many, as not only Armbian, but it's supported in other distro's, and OpenWRT has full support.
     
    If you don't mind OpenWRT - the GL-Inet B1300 is a great little box - It's based on the Qualcomm Atheros IPQ4028, which is a routing chipset with working dual-band WiFi - the factory firmware is built off Qualcomm's QSDK fork of OpenWRT (Chaos Calmer), and there's full support in OpenWRT 18.06 and master...
     
    QSDK has all the QCA accelerators for routing offload, and the closed source Wave2 Wifi drivers, so it's very well sorted.
     
    Factory firmware also includes OpenVPN Client/Server, along with Wireguard Client/Server, and gives direct access to OpenWRT's LUCI interface - their UI is a skin of LUCI, and for many might be good enough. I should mention that it also has Cloudflare DNS-over-TLS support built in - and all the OPKG's that OpenWRT has in their distro.
     
    For $90USD, it's a lot of bang for the buck, and a very hackable little device.

    FWIW -  There's armbian specific services in systemd that you might want to actually disable - armbian-ramlog for example, as when it runs out of space it gets ugly.
    systemctl list-unit-files | grep armbian armbian-firstrun-config.service            enabled         armbian-firstrun.service                   disabled        armbian-hardware-monitor.service           enabled         armbian-hardware-optimize.service          enabled        armbian-ramlog.service                     disabled        armbian-resize-filesystem.service          disabled        armbian-zram-config.service                disabled  Anyways - the ram logging and ZRAM stuff tend to be problematic for some that come into Armbian from other platforms...
     
    The two services I would disable from SystemD are below:
    armbian-ramlog.service armbian-zram-config.service  
    I know folks might be offended here - but disabling this results in expected behavior.

    Did you use the armbian-build-system for generating the image/kernel? :  https://github.com/armbian/build
    This can be done in a VirtualBox or a unused real PC.
    I think there you havent to activate much i2c stuff, but after booting activating i2c through the armbian-config and reboot.
     
    For myself I disconnected the OLED-Screen and did put the Neo2 now in the silver NAS-Case from FriendlyARM
