AM5728: Unable to get correct capture with ov5640 (green/pink screen issue)

Devashish Tiwari

Part Number: AM5728

Hello,

I have a custom board based on TI's AM5728 EVM. I am using the latest Linux PSDK 6.03 on it. I have ported the OV5640 Camera on the custom board.

I am trying to capture using yavta test but I am failing to do so. The capture file is producing incorrect output.

Following are device tree entries that I have used -

clk_ov5640_fixed: clk_ov5640_fixed {
                        compatible = "fixed-clock";
                        #clock-cells = <0>;
                        clock-frequency = <24000000>;
                };
clk_ov5640: clk_ov5640 {
                        compatible = "gpio-gate-clock";
                        #clock-cells = <0>;
                        clocks = <&clk_ov5640_fixed>;
                        enable-gpios = <&gpio5 18 GPIO_ACTIVE_HIGH>;
                };

&vin3a {
        vin3a_ep: endpoint {
                remote-endpoint = <&cam>;
                slave-mode;
        };
};

&vip2 {
        status = "okay";
};

&i2c3 {
        status = "okay";
        clock-frequency = <400000>;

        ov5640@3c {
                compatible = "ovti,ov5640";
                reg = <0x3c>;
                clock-names = "xclk";
                clocks = <&clk_ov5640>;
                powerdown-gpios = <&gpio5 17 GPIO_ACTIVE_HIGH>;

                port {
                        cam: endpoint {
                                bus-width = <8>;
                                data-shift = <2>;
                                hsync-active = <1>;
                                vsync-active = <1>;
                                pclk-sample = <1>;
                                remote-endpoint = <&vin3a_ep>;
                        };
                };
        };
};

I have enabled ov5640 driver in the kernel and I am taking care of all its dependencies as well. I am using the same driver code which is present in Linux 6.03 PSDK. Path for the driver is -

~./ti-processor-sdk-linux-am57xx-evm-06.03.00.106/board-support/linux-4.19.94+gitAUTOINC+be5389fd85-gbe5389fd85/drivers/media/i2c/ov5640.c

After booting to the kernel with the above changes, I am getting -

1. Camera device detected at i2c

PROBLEM -

I am trying to run yavta test and capture the stream in a file. When I try to play the file on my PC using ffplay, I am getting a complete green screen or pink screen on the player.

I am using the following command to capture the stream -

Also, I don't get why I am getting 2.930 fps in the output of yavta command. I am setting fps to 30 as default in the probe() function of the driver code (attached below).

I am using the following command to play the steam on my PC -

Also, the output I am getting is completely green and pink images on the player.

Please note that I don't have any display device connected to the custom board as of now. Hence, I am first capturing the stream in a file and then playing it on PC.

Kindly suggest why I am getting the incorrect output. Also, is there any other utility by which I can capture correctly from the camera device?

Hi Devashish,

From the output, I can see that your capture is working fine but the data is not correct.

I believe this may happen in case you pinmux is not setup correctly.

You can confirm this by doing a hexdump of the generated file to see if all the bytes are same.

Also refer to the appnote https://www.ti.com/lit/an/spracd3/spracd3.pdf that may be of help in debugging

Specially the section 4.1.2 about checking if pinmux is correct. You can verify if all the data lines are

toggling or not.

I used 7yuv tool on the PC to easily visualize the captured frames.

You may find it useful.

Hi Nikhil,

I took the hexdump of a capture file and I can see that all bytes are not the same in the output.

Here's the PINMUX configuration that I am using for the custom board.

I stumbled upon this app note (https://www.ti.com/lit/an/spracd3/spracd3.pdf) earlier and I ran iodelay-config utility on host/PC to generate vin3a-probe.sh script.

While running vin3a-probe.sh on the custom board. I could see that data lines are not toggling.

But then I also ran this same script on the TI AM5728 EVM and I got the same output. The data lines are not toggling even on EVM. The capture, however, works on AM5728 EVM. Note that the camera module on AM5728 EVM is different (OV10635).

I also tried to run a capture and then probe the data lines simultaneously but still got nothing on the custom board and EVM. I am attaching the script and its output below.

Also, I would like to update you that I have changed data-shift to <0> from <2> after discussing with my hardware counterpart, in case it matters.

Hi Nikhil Devshatwar,

I would like to update you on the new observations. The script I was running earlier did not have the correct values of GPIO and pad addresses. On changing, the values of GPIO, I could now see that the data lines are toggling whenever I start a capture.

The script I am running is as follows -

Please note that I am using the following values of control line polarities in device tree entries on the custom board.

hsync-active = <1>;
vsync-active = <1>;
pclk-sample = <1>;

Since the data lines are toggling, I am hoping there is no issue with the PINMUX configuration.

However, I am still not able to get the correct capture from the camera.

Hi Devashish,

I'm in exactly the same situation here...trying to get OV5640 to work with AM5728. Let me know if you found the solution.

Hi Nikhil,

I would like to update you about the progress with the camera module on the TI AM5728 based custom board

I am now able to get the preview from the camera and can display it on LCD.

I am using dmabuftest (https://git.ti.com/cgit/glsdk/omapdrmtest) to display camera preview on LCD. I am using following command -

dmabuftest -s 54:1024x600 -d /dev/video1 -c 1280x720@YUYV

The LCD resolution is 1024x600. I have attached a video recording from the phone of the same. I now have following queries -

1. Due to space constraints, the camera module is placed at a physical orientation of 90 degree counterclockwise on our board. Therefore, the preview is also rotated by 90 degrees during capture. The OV5640 datasheet does not support degree rotation. It only supports 0 degree and 180 degree rotation. Is it possible to rotate the camera preview by 90 degree from SoC side?

2. The camera preview is coming only in half of the LCD screen at 1280x720 resolution. And the image seen in preview is not complete but stretched. What timing register settings (HTS, VTS) can be used to resolve this issue?

3. Also while using camera with lower resolution (640x480), same issue is observed. The image is displayed only on half of the screen. Also, some horizontal lines are seen in the preview. How to resolve this?

Kindly acknowledge and revert.
