    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
  3. 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.

    K1 plus dual with battery power:
  7. 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.
  12. 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?

    Display ili9341 on H5

    It runs almost everything now with Larry's work

    Does anyone get SSH & VNC disconnections?

    In my experience, most of the time the SBC hangs is when all 4 cores are busy for too long the system overheats and CPU scaling causing the system to be unresponsive. CPU scaling does work as far as cutting down the load but somehow the affected processes do not like it and i have to reboot.
  15. You could also try a multi hdmi monitor switch, they are not too expansive.
