    Pine A64 MIPI DSI mainline

    in Pine A64

    Posted

    Hi Learnincurve ,

     

    I have a banana pi M2U and a SOM with R40 or A40i that I tried to run mipi_dsi over there but at this moment is not working ... I will try to download or clone the github from amarula and understand what change to run mipi_dsi on the Core R40 that have the same register that A31 and A64... If I run the mipi_dsi I post here how to do that...

     

    Best Regards Diego

    Enable sound on Banana Pi M2 Ultra

    in Beginners

    Posted

    I can enable bananpi M2 ultra sound (headphone and mic on pcb)  You must add this on the dtsi file.

     

            dma: dma-controller@01c02000 {
                compatible = "allwinner,sun8i-h3-dma";
                reg = <0x01c02000 0x1000>;
                interrupts = <GIC_SPI 27 IRQ_TYPE_LEVEL_HIGH>;
                clocks = <&ccu CLK_BUS_DMA>;
                resets = <&ccu RST_BUS_DMA>;
                #dma-cells = <1>;
            };

            codec: codec@01c22c00 {
                #sound-dai-cells = <0>;
                compatible = "allwinner,sun8i-h3-codec";
                reg = <0x01c22c00 0x300>;
                interrupts = <GIC_SPI 30 IRQ_TYPE_LEVEL_HIGH>;
                clocks = <&ccu CLK_BUS_CODEC>, <&ccu CLK_CODEC>;
                clock-names = "apb", "codec";
                resets = <&ccu RST_BUS_CODEC>;
                dmas = <&dma 19>, <&dma 19>;
                dma-names = "rx", "tx";
                allwinner,codec-analog-controls = <&codec_analog>;
                allwinner,audio-routing =
                    "Headphone", "HP",
                    "LINEIN", "Line In",
                    "MIC1",    "MBIAS",
                    "MIC1", "Mic",
                    "MIC2", "HBIAS",
                    "MIC2", "Headset Mic";
                status = "okay";
            };

            codec_analog: codec-analog@01c22f00 {
                compatible = "allwinner,sun8i-a23-codec-analog";
                reg = <0x01c22f00 0x4>;
            };

     

    Then modules that must be loaded are

     

    sun8i_codec_analog     24576  1
    sun4i_codec            32768  3
    snd_soc_core          118784  2 sun4i_codec,sun8i_codec_analog
    snd_pcm_dmaengine      16384  1 snd_soc_core
    snd_pcm                65536  2 snd_pcm_dmaengine,snd_soc_core
    snd_timer              24576  1 snd_pcm
    snd                    45056  3 snd_timer,snd_soc_core,snd_pcm
    soundcore              16384  1 snd

     

    to test the player execute that to check the sound

    $ aplay /usr/share/sounds/alsa/Front_Center.wav

     

    then execute

    $ alsamixer

    to control the volumen and gain

     

    To enable mic do that.

    1) open alsamixer;
    2) press "tab" to switch to capture;
    3) press "bar" on the first capture channel;
    "L_____R" red sign should appear;
    4) select by arrow key MIC as the source of the first
    input source;
    2) record a test file:
    arecord -f cd -D hw:0,0 -d 10 test.wav
    play it back to test i.e.:

    mplayer test.wav

     

    Thats all ...

    Enable Panel LCD on R40 AllWinner???

    in Advanced users - Development

    Posted

    I can compile the kernel 4.14 for H3 , modify the device tree and then put this to my bananapi M2 ultra with R40 Core and can enable the HDMI connector success.  I get an image on the screen on my monitor.

    But now I can enable the LCD (RGB pinouts port H) to get image on my display 7" but I do not know how to do on the device tree file to enable a PANEL or something more . Someone have a device tree file that have enable the LCD (RGB ouput) to take an example to know how to do that because on the web almost all the people usually use the hdmi connector.

     

    Thanks at all ...

     

    PD: I get success on R40 to modify the SPI, smartcard, ethernet drivers and have an Ubuntu 16.4 running (desktop) on the Bananapi M2 Ultra. Then I will explain how to do that.
