  1. Thanks for fast reply.

    I poked around DTB and i try to enable SPI, which was set to disabled, I changed it to okay, but after recompiling DTB and rebooting nothing happend.
    There is also entry onewire-touch, but I don't know what to do with it.

    spi@c005b000 {
                            compatible = "nexell,s5p6818-spi";
                            reg = <0xc005b000 0x100>;
                            interrupts = <0x0 0xc 0x0>;
                            dmas = <0x39 0x6 0x0 0x39 0x7 0x0>;
                            dma-names = "tx", "rx";
                            resets = <0x12 0x2c 0x12 0x2d>;
                            reset-names = "pre-reset", "spi-reset";
                            #address-cells = <0x1>;
                            #size-cells = <0x0>;
                            samsung,spi-src-clk = <0x0>;
                            num-cs = <0x1>;
                            clocks = <0x48 0x48>;
                            clock-names = "spi", "spi_busclk0";
                            pinctrl-names = "default";
                            pinctrl-0 = <0x49>;
                            status = "okay";
                    };
    //------
    
    onewire-touch {
                    compatible = "friendlyarm,onewire-touch";
                    interrupt-parent = <0x2e>;
                    interrupts = <0x10 0x0>;
                    i2c-bus = <0x6e>;
                    pinctrl-names = "default";
                    pinctrl-0 = <0x6f>;
            };


    In modules I found module onewire-touch, but nothing after loading.

    About DTB editing, I was able to find very little information about modifying. Can I be pointed to somewhere, where I can get info about it?


     

  2. Hello,

    I'm trying to get working my NanoPi Fire3 with HD702 screen and I found out some issues.
    I'm running Armbian_20.02.7_Nanopifire3_bionic_legacy_4.14.174 image on it.

    First and most significant is that the ethernet port isn't working properly. I cannot ping anything and if I try to deactivate and activate ethernet connection in Network Manager it says:

    After reboot, it's connected via eth, but if I try to ping something is also fails

    I connected my HD702 screen to board and if I install xubuntu-core/desktop... it works, but It's running via fb, thus it's slow and FriendlyArm OneWire touchscreen isn't working. I wasn't able to find information if is OneWire touchscreen supported in your kernel, or how to get it working.
    I wasn't able to find any information if is GPU in S5P6818 supported or if it's possible to have accelerated desktop environment on it.

    My last question is if SPI on this board works.

    Thanks in advance.
