    For what it's worth, I gave up on OPi.GPIO some time back, and switched to the standard libgpiod instead (e.g., see https://git.kernel.org/pub/scm/libs/libgpiod/libgpiod.git/about/).  Use of libgpiod eliminates almost all pain in terms of permissions to manage GPIOs for non-root users.

     

    I still use OPi.GPIO and it works fine for non root users with the proper udev rules. When I started using it I had to patch it to delay opening the files (the udev rules take some time to apply), but now it does it itself (it checks that the file is accessible before giving up).


  2. There are no drivers for the camera in mainline kernel. You have to use a version based on a legacy kernel (https://dl.armbian.com/orangepilite/Ubuntu_xenial_default_desktop.7z). I don't know the progress in mainline regarding gc2035.

    Edit: looking  at the table here  I see that the csi driver has been mainlined in kernel 5.0. Without that the camera cannot work. What I don't know is if the gc2035 driver is available in 5.0

    Dear olivluca, I read "man gpio". There no command "set"! May be need to use command "write"? And I dont know, how can understand what pin need activate for supply CSI of  OrangePiPcPlus??? PL10? PG11? where can I to read it? I'm really afraid to give voltage on wrong pin!

     

    The "gpio" there is an uboot command, not a linux one, so "set" is correct. I cannot help on the correct gpio to set for your board, mine is an opi pc.


  4. In the EU

    is this a Brexit shape of things to come?

     

     

     

    No, it's an EU thing

    Edit: didn't finish - but there are variations depending on each country. Here in Spain, over 22€ you have to pay VAT + handling charges (IIRC 20 or so €), over 150€ you have to pay VAT + customs duties + handling charges. Less that 22€ you pay nothing (in theory).

    But many parcels pass through customs with no charges (they cannot control everything).

    I also tried to boot the images with the 4.XX kernels and it won't work. Only the 3.14 - no issues there.

     

    Why is that?

     

     

    Because there is no dtb that works for the KI pro. The dtb for 3.14 cannot be used since the format changed.

     


  6. @erbas I didn't pursue this further. I'm currently running libreelec but with kernel 3.14, as it seems nobody has a working dtb for newer kernels and I'm not able to write one. With libreelec the dvb driver more or less works but worse than under android (with android I can tune both dvb-s/s2 muxes as well as dvb-t, with libreelec I have more difficulty tuning some dvb-s/s2 muxes and cannot tune dvb-t at all).

    Perhaps later I'll try armbian again on this box, but for the time being libreelec it is.
