    I am releasing this patch in the hope of you may find it useful. I have also included a sample dts file.  It seems to work in 48mhz quite well with very few SPI errors. (Note that the pieces of the driver has been around for some time but I have never seen it put together without further work. Hopefully this patch would make it readily usable. I have tested it on 5.5.18 and quite happy with it.)

    Sample file is for nanopi neo.


  2. I replaced all of my orange pi zeros with them as camera servers - combined with esp32s to serve as remote monitors. The one shown in previous message is a spare one to use as tool chain builder, also can be used standalone.

    install all the necessary systems (Win Debian Ubuntu etc) together and select the desired system when you turn on your PC. This is much better than using virtual versions.

    VMs are a must, hosts should not be connected to IP networks for security but the VMs can. VMs can be generated on the fly using templates (file copies).  It is far easier to blow away a file than a partition. The goal should be to run more VMs simultaneously, not rid of them. :)


  4. If you can live with hdmi being not working in the mean time, I would recommend OPI One Plus or Lite2. They are just faster H5's and they work with
    little heat sinks. I used them to compile the esp32 cross tool chain which took like two hours and they just worked. Before this I also had high hopes
    for k1 plus but it crashed like 20 minutes into the compilation - this was using the bigger stock heat sink without fan - my PCs are already making
    enough noise for me. Heat is the biggest problem for any serious computing using these boards. Note that CPU throttling worked amazingly well on these
    H6 boards, the temperature never got higher than 78C and the CPUs were throttling between 1.5/73 to 1.8/78. They are also cheaper, for the lack of
    USB's, I use a $2 hub, SPI lcd works in 4.20, but not 5.1.

    +- BUT also no soundcard (HDMI or analog) which seems to be available in the Pine64-image when started 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.


  6. 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.
