Camera module for OLinuxINO A64

[Eric976]

Hello guys
I just bought a OlinuxINO A64 board but I'm kind of lost with the camera input. Can someone help me?
1) The MiPi input has 20 pins? Which camera module have you guys already used there?
2) I bought an IR Camera for Raspberry PI, I though that it would work with OLinuxINO, but it didn't, because the RPI camera has 22 pins, and even with different order. Is there a way to convert?
3) To use a CSI camera, just using the GPIO extension connector, right?

Please, share your thoughts about camera modules with this board with me.
Thanks in advance.

We haven't used the MIPI interface ourselves. One important thing for the MIPI connector and options is that it is MIPI DSI (not MIPI DSI-2 which is the more widespread standard). There are a lot of places with more information about the DSI you can also read in wikipedia: https://en.wikipedia.org/wiki/Display_Serial_Interface and also here: https://www.mipi.org/specifications/display-interface

Another important point is that it is not clear how good the Linux and mainline support for the MIPI DSI is - even if you establish the hardware connections you might need to alter the Linux image to get it working.

What is the RPi camera that you bought exactly? Pi NoIR Camera V2? It is CSI I think.

Yes, CSI is available on the GPIO header.

Thanks for your answer.
I bought the OV5647 module with 22 pins, for the Raspberry PI Zero standard, this camera had all prerequisites that I was looking for, that are good price, 5MP, full hd and infrared vision.
I checked the pins for the 22 pins connector, it seems to use the MiPi pins. So I bought a adaptors from FPC to DIP to connect everything together using wires in the prototype phase. Is there a better way to test this camera module with the A64 board?

[Eric976]

Hello guys
I'm still stuck with the camera issue...
I saw the list of cameras that are compatible with OLinuxINO board that is available clicking in "Camera Support List" here https://www.olimex.com/Products/Components/Camera/CAM-GT2005/.
So I bought the camera OV5640, with all pins for a CSI connection, using the pins available in the GPIO connector.
I connected but it didn't work automatically, how can I configure it?

Hello
Can someone help me? I'm still stuck with this situation. 

[Eric976]

Hello again, guys
I think that I'm almost there...

I came back to the first camera module that I was testing, the OV5647, because I saw the driver already included in the kernel. So let me post some results I have so far with the board A64-OLinuxIno Rev C.

The hardware connections that I've done

One more update, I can see the driver, but there is no video in the device "video0".

I keep trying.

                                };

        };

        fragment@1 {
                target = <&dsi>;
                __overlay__ {

                        vcc-dsi-supply = <0x04>;

                        port {

        };

        fragment@2 {

                __overlay__ {
                        status = "okay";
                };
        };
};

I added the fragment 2 to solve the D-PHY error, that I said before, and I added "vcc-dsi-supply = <0x04>" because I had an error related to this.

Someone?

[LubOlimex]

I looked again everything and I think there is a major problem with the setup. I believe the interface is called MIPI_DSI for a reason. "DSI" is short of "Display Serial Interface". The MIPI connector is only output, aka it can be only used with a display, and NOT with a camera.

There were many places this was mentioned but unfortunately we missed it the first time around.

I checked again the datasheet of the main chip A64, and if you look at the features listed on page 10 the only image input interface mentioned in "2.7. Image In" is CSI (not MIPI). The datasheet is here:

https://dl.linux-sunxi.org/A64/A64_Datasheet_V1.1.pdf

So CSI cameras can be used with A64 chip, track the CSI signals. CSI signals are from PE0 to PE13 and all are free and available on the GPIO1 connector. It is pins 5,7,9,11,13,15,17,19,21,23,25,27,29,31.

Ok =/
So I will come back to the camera OV5640, but the driver is not included yet, I'll research more about this.

[Eric976]

Hello
So I came back to a module with the OV5640 camera. The module is from Alientek company and it already has a crystal and the different voltages needed for the camera.
And for this it was necessary to recompile the kernel, to add the OV5640 driver. The driver I used was the c file available in the Olimex Kernel (https://github.com/OLIMEX/linux-olimex).

My dts file is as following:

I could get a picture using the fswebcam available in https://github.com/avafinger/fswebcam and following the instructions.
But I cannot get any video, I tried with gstreamer, ffmpeg, cheese, VLC... I'm always getting a message related to memory or pipeline, mostly about pipeline.
What can this be? Is it hardwarerelated or software?

[LubOlimex]

Nice! If you have gotten a picture then things are going alright. Especially the hardware connections are alright. Shame that fswebcam is meant only for taking pictures. Probably some of the software settings in the command line of the tool are unfitting for the video. There might be other packages required. Stick with one video capturing software and check its related forums for similar errors. Maybe it is just something in the settings, but it might be a sign of missing kernel mpodules.

I got a video! =D
But a recorded one, not real-time. VLC and Cheese are still not working.
The problem with the pipeline was a misconfiguration done using the command media-ctl.

I tested using this pipeline
