xeniter Posted October 1, 2018 Posted October 1, 2018 Hi i try to get a ov5640 camera running on a banana pi m2 plus board. i builded the csi driver and it gets loaded, however i am not able to take picture: root@bananapim2plus:~/cap-v4l2# ./cap 1280 768 4 1 -999 -1 -1 ---- cap parameters ----- width: 1280 height: 768 v4l2 buffers: 4 exposure: -999 hflip: -1 vflip: -1 Mode: V4L2_MODE_VIDEO Driver: "sun6i-video" Card: "sun6i-csi" Bus: "platform:camera" Version: 1.0 Capabilities: 84200001 v4l2: unable to enumerate input. v4l2: failed to init camera. root@bananapim2plus:~/cap-v4l2# dmesg [23141.993618] sun6i-csi 1cb0000.camera: -> sun6i_csi_set_power() [23141.993653] sun6i-csi 1cb0000.camera: -> sun6i_csi_set_power() =>DONE_1 [23142.007416] sun6i-csi 1cb0000.camera: -> sun6i_csi_set_power() [23142.007451] sun6i-csi 1cb0000.camera: -> sun6i_csi_set_power() =>DONE_2 Does anyone know how the video 4 linux call path is for initializing a camera? I loaded the ov6540 module but it never gets probed. i assume the i2c must be somehow linked in the dts file together, but i wasn't able to find a complete working example. my dts file now, which loads at least the sun6i-csi driver but it should be insert i2c section, if i put it there, i does not get loaded. csi { status = "okay"; port { #address-cells = <1>; #size-cells = <0>; // Parallel bus endpoint csi_from_ov5640: endpoint { remote-endpoint = <&ov5640_to_csi>; bus-width = <8>; data-shift = <2>; hsync-active = <1>; // Active high vsync-active = <0>; // Active low data-active = <1>; // Active high pclk-sample = <1>; // Rising }; }; }; camera@1cb0000 { compatible = "allwinner,sun8i-h3-csi", "allwinner,sun6i-a31-csi"; reg = <0x1cb0000 0x1000>; interrupts = <0x0 0x54 0x4>; clocks = <0x3 0x2d 0x3 0x6a 0x3 0x62>; clock-names = "bus", "mod", "ram"; resets = <0x3 0x1e>; pinctrl-names = "default"; pinctrl-0 = <0x27>; status = "okay"; phandle = <0x63>; // powerdown-gpios = <&gpio1 19 GPIO_ACTIVE_HIGH>; // reset-gpios = <&gpio1 20 GPIO_ACTIVE_LOW>; //powerdown-gpios = <0xc 0x3 0xd 0x0>; // PD14 active high ?? port { ov5640_to_csi: endpoint { remote-endpoint = <&csi_from_ov5640>; bus-width = <8>; data-shift = <2>; hsync-active = <1>; // Active high vsync-active = <0>; // Active low data-active = <1>; // Active high pclk-sample = <1>; // Rising }; }; }; According to the kernel doku: https://elixir.bootlin.com/linux/latest/source/Documentation/devicetree/bindings/media/video-interfaces.txt it should be a device node from the i2c, but then it doesn't load the camera modul. If i add compatible="ovti,ov5640" the ov5640 modul get loaded but does not to anything. no even a simple print, which modul/function/program should call the i2c probing? when i load i2c normal, the modul works (i2cdetect does probe something on the i2 lines). Next isse i have, the V4L2 looks like changed to a builtin modul, is it somehow possible to change it back to a modul? would like to printk debug the v4l2 async file. When i set it back in the config file to "m" it asks again and says this is a invalid option? Anyone an idea? or have a working dts file for a ovXXXX camera with i2c running with the sun6i-csi modul?
xeniter Posted October 3, 2018 Author Posted October 3, 2018 got it finally running, still some issues got first picture main problem was DTS setup (clocks and pins configuration) if anyone would like to get it running (OV5640 on a banana pi m2 plus board (sun8i-h3 allwinner) with latest dev kernel (4.18.11)) build armbian for banana with dev branch: ./compile.sh KERNEL_ONLY=no BUILD_DESKTOP=no INSTALL_HEADERS=yes BRANCH=dev RELEASE=stretch BOARD=bananapim2plus -j4 choose change kernel config, choose following as modul: CONFIG_VIDEO_OV5640=m CONFIG_VIDEO_SUN6I_CSI=m i prefer moduls for debug purposes adjust DTS file for Camera and CSI interface, not sure if its completely correct, at least i got a picture /dts-v1/;
