    I can not switch channels other than 36 and 44

    Getting the 5GHz channels - you need to set the regulatory domain... look at cfg80211 in your messages...

    Lichee Pi zero

    Yep, it's a bit tight for a full flavored linux - but hey, OpenWRT/LEDE has squeezed into tighter footprints than 64MB... I'm just a bit puzzled as to why Allwinner chose to not put some NAND in the package along with the DDR2 on the V3s - going TSOP was a good move, IMHO...

    Lichee Pi zero

    I've had $5 ChinaPost EMS ePacket from another vendor as well - sometimes slow and sometimes fast (last order was 5 days from Shenzen to San Diego, previous order was 3 weeks)

    Quick Pinebook Preview / Review

    Outside of the PineBook and the RPi based items... ChromeOS - Samsung Chromebook Plus (1st gen) and Acer R13 (CB5-312T-K5X4) support Crostini (Linux KVM as guest OS running Debian) and Android's Google Play Store... both of these are ARM based, and there are other ARM chromebooks that might also be useful...

    New development board, how to add it to Armbian?

    FriendlyARM does do a decent job compared to some of the others out there... between what they provide and what the Linux-Sunxi folks have put together it's fairly easy to work with the Allwinner FE boards at least. SolidRun is really good on their documentation, and would be considered a good model to emulate.

    New development board, how to add it to Armbian?

    Based on previous experience. Documentation - be really clear and concise with docs - the Product Requirements (why we're doing it), the Product Definition (how we're going to do it), the Hardware Design Spec (how it's going to be done), SRD/SDD for software if this is a software driven project - and most important, the Business Plan for the project. If you're focused on the developer market, the documentation is going to be the key driver of your success in either finding partners, or selling the project off to a third party. There's always an exit - fail and roll it up, sell the design to someone else that can scale, or scale up oneself if one has the money to do it. (in my case, we chose door number two - sell the design - the documentation was the one item that saved the project - the hardware is history, but the architecture was enough that we were bought out - hardware is expensive to forge the path, and cheap once it's done, software on the other hand...) Biz Plan - it's the vision - what we're doing, and how we do it within a budget - the product, the competitive space it's going to be in, how will we make money? The biz plan is the most important - and that's to understand the risks going in - if one is working out of Taipei or San Diego, keep in mind that once the product is out there, there's going to be a shedload of folks in Shenzen that will do their very best to reverse it and build clones*, and they will sell them at BOM or close to it, undercutting your product... * Because - this is shenzen, and that's what they do, build product... Software support is going to be key - the boards you have, they can be done for less than $20USD, so one has to look at the value added components...

    How to completely disable log2ram?

    The ones to look for... again, it's there for a good reason, just like armbian-zram-config.service (which some might be aware of as docker and k8 can have issues with swap in general) $ 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 to disable the ramlog service - systemctl disable armbian-ramlog.service as sudo

    The RAM bump is enough... Best of luck with the project - wish you and the team great success!

    NanoPI M4

    I would agree - not everyone mills aluminum cases out of larger blocks unless they're a certain company out of cupertino... Silly Excess here - and for a startup - costing is going to be a problem...
  11. Prior to entering an issue... One of the challenges of using an image based install is how to cover to machine unique items... Good example here is the systemd-machine-id... some systemd units can use machine-id in place of gethostid... https://www.freedesktop.org/software/systemd/man/machine-id.html It's supposed to be a unique qualifier for installation - but if this is written into the image, it's going to likely be the same for every image out there... Can always regen it on the shell - but this could also be in the first run script... $ cat /etc/machine-id \ && sudo rm -rf /var/lib/dbus/machine-id \ && sudo rm -rf /etc/machine-id \ && sudo dbus-uuidgen --ensure \ && sudo systemd-machine-id-setup \ && cat /etc/machine-id The other is the ssh_host* keys - which is a bit more important, as we don't neccessarily want every install to have the same ssh_host oriented keys... $ sudo /bin/rm -v /etc/ssh/ssh_host_* $ sudo dpkg-reconfigure openssh-server $ sudo systemctl restart ssh This one can cause issues with subsequent sessions, if the openssh-client is doing strict checking - easy enough to fix using ssh-keygen -f "<local path to .ssh/known_hosts" -R ipaddr Are there other considerations - for example, locally administered OUI's for Ethernet/WiFi if they don't have a eeprom burned global OUI? Thoughts?
  12. And since you mention RASPI - Raspbian include the RealVNC Server and Client, and RealVNC clients are available for most platforms. I used to use NX (From NoMachines) a long time ago - it's neat stuff, but time has moved on...

    Hey - I know you I think the old adage applies here - good artists copy, great artists steal - keep in mind that many of the AW H-series boards are very similar, so uBoot and Device Tree is really the challenge, and there, it's probably not as hard as trying to bring up a completely new SoC from an outside vendor. BTW - Nice board, clean layout - if one could bump up the RAM and eMMC (let's say 2GB/32GB), it could be a compelling little board...

    If you must... armbian-ramlog is a good place to start looking, along with armbian-zramconfig
