    research Armbian in 3D

    But those were supposably soldiers buried alive...

    What does your workbench look like?

    Here is mine:

    Orangepi zero plus2 H3 (4.19.20)

    I have been having the same problem for a number of images, I ended up having to add a user patch to use the uboot in May.
  5. Thanks to everyone for the work here, so if you use armbian-add-overlay on the created file below, it should just work in the future. usbotg2host.dts
  6. Alternatively, you could use a usb to ethernet connector, this would give you network (my user build next works just fine and boots - I just did it today).

    [Experiment] armbian on NanoPi A64

    That's right analog sound seems available (as shown by /proc/asound/cards) when using a pine64 5.70 next image with nanopi a64 but no sound ever comes out of the connection, wifi does work.

    BananaPi M2+, how to Overlayfs ?

    I haven't, but you may want to try this aufs blog post: https://superuser.com/questions/833576/differences-of-aufs-unionfs-and-overlayfs-from-each-other

    Orange Pi PC - A disaster ?

    If you add anything crappy to your system, your system would become crappy because it is contagious. I always baby mine and they provide me with joy.

    SPI issue on BananaPi M2 (sun6i)

    Still has SPI 110 errors, but seems less frequent on 4.19.y, double spi and analog audio still works.

    Small monochrome displays

    Wouldn't you opt for an oled display instead, brighter, smaller, and higher resolution for fifty cents more? And its using only 4 lines, sample usage:

    Recommended SBC below 20USD range.

    Here are some of my SBCs that are under $20 (see photo below). I have divided them into two categories, with hdmi and not. The ones on the left are without, and on the right are with. The ones without are mostly orangepi's and nanopi's. Just do a search on their web sites and if it is under $20, I have it. One thing to consider is the ones with two spi channels (e.g. nanopi core 1 - note core 2 is better but its over $20), this would allow connecting two spi screens. If you connect two relatively big 3.2 ili9341 screens, with the browser stretched across them, your experience would still suffer but it would be okay in some extreme situations. The ones with hdmi include, raspberrypi zero w (double spi), nanopi A64 (double spi), pcduino4 nano (double spi), nanopi m1 - same as pcduino4 nano (double spi), and the other three orangepi's. Bananapi zero is slightly over $20, I have it connected to a lap dock. Of these, the best is pcduino4 nano (get it on ebay between $5 to $16), supported well in software (armbian), and nanopi a64 ($19.99?) is my second choice, software support is getting there (may be?), at least double spi works with pine64 image (latest kernel). Raspberrypi Zero W is only $5 from my local store, and dual spi screen with camera works, you really can't beat it in price.

    Banana Pi Zero

    CSC supported is just as great as any other boards. The only thing I could not get working is hdmi sound, wifi works fine, both spi channels work fine - but not as well as other boards (more 110 errors), perhaps hardware related? I use it as a laptop with my lap dock, and a bluetooth dongle for sound.

    Mini handheld linux console :)

    You could easily do that with any SBC discussed in this forum, e.g. k1plus dual screen + bluetooth keyboard, or a zero plus 2 h5, 5 inch hdmi + bluetooh keyboard, or a pi zero with double 18650 batteries and a 2.4" screen
  15. The issue is question is missing spidev argument: param_spidev_spi_bus=0 I can confirm spi_spidev works in 4.17.11. But I could not get other user device tree overlays to work properly in 4.17.11.

    Dual screens anyone?

    Tinker board dual - work in progress:
  17. I must admit I don't really know what to do with my sbc's. After getting them set up there is nothing more I could think of to use them for. I guess part of the fun is in getting them set up, and to run them cool during native kernel builds. Just so it's not a complete waste of money, I spent more (though not a lot) to add dual screens to some of them. Any ideas what else I could use them for? I already have music players (a lot of them, DACs), NAS, home control, security camera, what else do you use them for? I haven't left any of them outside in the sun yet to try out solar power. So, I added dual screens to these ones (left to right, counter clockwise) nanopi neo core, bananapi m1 (original banana pi), pcduino 4 nano (same as nanopi m1), bananapi m2 (a31s), and raspberry pi 3. All of them have two separate SPI channels, it was fun in making them, getting videos to play in dual screens (though not accelerated, but still ran fine in software), but now what? Almost forgot, all of them are running Armbian next (except the raspberry) and thanks for the good work here!!!.

    Dual screens anyone?

    K1 plus dual with battery power:
  20. Accidentally clicked on kodi while looking for smtube and surprised to see it on my SPI display - no more DRI authentication errors :-) This was on a OPI Prime (H5), kernel 4.17.10.

    NanoPi K1 Plus to be released soon

    Happy to report both SPI channels worked properly with 5.47 stable using 4.14.51-sunxi64:

    failure rate of SBC boards

    I have no less than 50 SBCs from different vendors, including OrangePi, BananaPi, RaspberryPi, and NanoPi. All of my failures came from NanoPi, so much for providing boards with industrial quality. These were all DOA's: - one NanoPi Neo microSD slot failed to latch, new board, shipping not refunded - two of the mini shields for Neo Core/Core2 failed to do anything - I bought four of these kits, the failures were never refunded - four UNO dock V2 - I bought 4 of these, all of them not working, never refunded I do like the NanoPi boards when they work, but their quality control is terrible.
  25. Not sure if this has been reported - the usual way of enabling spi overaly "overlays=spi-spidev and param_spidev_spi_bus=x" seems to be broken and when an overlay fails at boot time, it tries to load the base dtb from /.../alllwinner/allwinner/*, note the extra allwinner in the path - so it fails. The pin definitions for the Euler SPI are wrong. When you manage to get both SPIs up. SPI 0 is being enabled as spi1.0 and SPI 1 being enabled as spi0.0. It also fails to merge board neutral ili9341 SPI definition files (at boot time) that has always worked on H3 and H5 boards. To work around for now, use the following ( spi0.dts, spi1.dts) to get the spidev's up - not sure why these worked and spi-spidev didn't (is it because of the parameter requiring fix-ups?). Also note they enable the wrong spi. After they are added, SPIs are working as you can use notro's fbtft (via modprobe) on them but not both at the same time. Cannot readily use 5.44 yet as the kernel headers are missing. I understand SPI is not in the matrix until 4.15 - how to report these issues so they can be fixed soon?
