MIPI-CSI on iMX8M Mini with ADV7282A-M

Hello,

I am trying to run iMX8M Mini with ADV7282A-M chip, but I have some problems with drivers.

For now I'm using these drivers specifically:

ADV7282A-M: /drivers/media/i2c/adv7180.c
MIPI-CSI-2: /drivers/media/platform/mxc/capture/mxc_mipi_csi.c
CSI-BRIDGE: /drivers/media/platform/mxc/capture/mx6s_capture.c

But it looks like this drivers from /media/platform/mxc/ cannot work with ADV driver from /media/i2c/. Is this true?

In dmesg every part separatly looks totaly fine, ADV, MIPI-CSI and CSI-BRIDGE are completly initialized but when I'm trying to use it with "v4l2-ctl --all" there is no capabilities (like resolution 0/0).

Hi @khang_letruong , 

1) I can't use https://source.codeaurora.org/external/imx/linux-imx/tree/drivers/media/platform/mxc/capture/adv7180... (I really would like to) because this is driver only for iMX6. You can't compile kernel for iMX8M Mini with this driver, because iMX8M Mini don't have IPU (which is necessary for this driver). 

2) I'm sending my Device Tree and Dmesg logs in attachment.

dmesg:

Hi @khang_letruong 

Did you make your modification within imx8mm.dtsi or imx8mm-evk.dtsi ?  imx8mm.dtsi should not be modified.

No, I've created new DT file 'visionsom-8mm-custom.dts' which is directly loaded by U-Boot as the main Device Tree file. This file body is: 

 

/dts-v1/;

#include "freescale/visionsom-8mm.dtsi"
#include "adv7180.dts"
#include "ksz8081.dts"

/ {
    model = "VisionSOM i.MX8MM ACO Custom";
};

 


'imx8mm.dtsi' file is loaded by 'freescale/visionsom-8mm.dtsi' and in the 'adv7180.dts' file are my changes mentioned earlier. 
'freescale/visionsom-8mm.dtsi' is available here: https://github.com/SoMLabs/somlabs-linux-imx/blob/somlabs_imx_5.4.24_2.1.0/arch/arm64/boot/dts/frees... 

I thing that this is working, because adv7180.c driver is loaded - and this is configured in this 'adv7180.dts' file with my changes.

Hi again,

And you should enable the debugging message of above driver to see where it was stuck, for example :
- Is the i2c communication successful?
- What /dev/videoX is registered for your driver?
- ...
Best Regards,
Khang.

Hello @khang_letruong khang_letruong,

This driver (adv7180.c) is working totally fine, it's not a case. Driver is fully probed and loaded, in system DMESG there is a message "adv7180 0-0021: chip found @ 0x21 (30a20000.i2c)".
Also all i2c addresses are successfully initialized (0x21, 0x42, 0x44).
But this driver is not creating any /dev/videoX (it's not supposed to).

The driver which is creating '/dev/video0/' device is:
https://source.codeaurora.org/external/imx/linux-imx/tree/drivers/media/platform/mxc/capture/mx6s_ca...

And it is listed when i'm doing 'v4l2-ctl --all'.... BUT this driver is not "talking" with adv7180.c driver.

I read somewhere that mainline drivers from /drivers/media/i2c/ are not working with drivers from /drivers/media/platform/mxc/ because there are using different V4L2 API. Is this true?

What should I do now?

Thanks

Hi @KubaACO ,

Looking at the entry point of the driver you are using :

static int adv7180_probe(struct i2c_client *client,
                         const struct i2c_device_id *id)
{
        struct adv7180_state *state;
        struct v4l2_subdev *sd;
        int ret;

        if (!i2c_check_functionality(client->adapter, I2C_FUNC_SMBUS_BYTE_DATA))
                return -EIO;

        v4l_info(client, "chip found @ 0x%02x (%s)\n",
                 client->addr, client->adapter->name);

        state = devm_kzalloc(&client->dev, sizeof(*state), GFP_KERNEL);
        if (state == NULL)
                return -ENOMEM;

        state->client = client;
        state->field = V4L2_FIELD_INTERLACED;
        state->chip_info = (struct adv7180_chip_info *)id->driver_data;

        state->pwdn_gpio = devm_gpiod_get_optional(&client->dev, "powerdown",
                                                   GPIOD_OUT_HIGH);
        if (IS_ERR(state->pwdn_gpio)) {

                                ADV7180_DEFAULT_VPP_I2C_ADDR);
                if (!state->vpp_client) {
                        ret = -ENOMEM;
                        goto err_unregister_csi_client;

        else
                state->powered = false;
        state->input = 0;
        sd = &state->sd;
        v4l2_i2c_subdev_init(sd, client, &adv7180_ops);

        }

        ret = v4l2_async_register_subdev(sd);
        if (ret)
                goto err_free_irq;

        return 0;

err_free_irq:
        if (state->irq > 0)
                free_irq(client->irq, state);
err_media_entity_cleanup:
        media_entity_cleanup(&sd->entity);
err_free_ctrl:
        adv7180_exit_controls(state);
err_unregister_vpp_client:
        if (state->chip_info->flags & ADV7180_FLAG_I2P)
                i2c_unregister_device(state->vpp_client);
err_unregister_csi_client:
        if (state->chip_info->flags & ADV7180_FLAG_MIPI_CSI2)
                i2c_unregister_device(state->csi_client);
        mutex_destroy(&state->mutex);
        return ret;
}

 

It's still early to make the following conclusion :

This driver (adv7180.c) is working totally fine, it's not a case. Driver is fully probed and loaded, in system DMESG there is a message "adv7180 0-0021: chip found @ 0x21 (30a20000.i2c)".
Also all i2c addresses are successfully initialized (0x21, 0x42, 0x44).

I would suggest you to put an info message to make sure that your driver has been successfully probed (adv7180_probe() returns 0):

        ret = v4l2_async_register_subdev(sd);
        if (ret)
                goto err_free_irq;

         v4l_info(client, "Driver for adv7282-m successfully probed\n", client->addr);
        return 0;

- Otherwise, add an error message (v4l_error(...) ) for each return different than 0.

I would guess that the I2C communication from the iM8M Mini SoC to the adv7282-m has not been established yet.

K.

Hello @khang_letruong 

First of all - Thank you so much for trying to help me! I hope we can find a solution together.

Unfortunately - there is some mistake. adv7180.c driver which I'm using is:
https://github.com/Freescale/linux-fslc/blob/5.10-2.1.x-imx/drivers/media/i2c/adv7180.c and in this driver function 'adv7180_probe()' is different from the one you are quoting.

As You can see in this driver: 

v4l_info(client, "chip found @ 0x%02x (%s)\n",
		 client->addr, client->adapter->name);

this log is printed at the very end of the probe function so I assume all this function is working correctly.

What do You think about it? 

PS Could You give me a link to driver file which You are quoting?

Hi @KubaACO ,

What do You think about it?

Sorry for the confusion. I took it from a very old version, I switched to that version to check how I did implement my own driver for iMX8M Mini before as you said : 

1) I can't use https://source.codeaurora.org/external/imx/linux-imx/tree/drivers/media/platform/mxc/capture/adv7180... (I really would like to) because this is driver only for iMX6. You can't compile kernel for iMX8M Mini with this driver, because iMX8M Mini don't have IPU (which is necessary for this driver).

And, I put my own driver to the same location as the ov5640_mipi_v2.c under drivers/media/platform/mxc/capture/ in which there's another adv7180.c driver developed / maintained by Freescale/NXP while the drivers/media/i2c/adv7180.c is upstream and developed by Analog Devices, its maker.

Regards,
K.

@khang_letruong 

Ok, sorry but i'm not quite understand:

And, I put my own driver to the same location as the ov5640_mipi_v2.c under drivers/media/platform/mxc/capture/ in which there's another adv7180.cdriver developed / maintained by Freescale/NXP while the drivers/media/i2c/adv7180.c is upstream and developed by Analog Devices, its maker.

So You wrote Your own driver to the ADV7180 (or similar)? And with this driver it is all working fine?

Hi @KubaACO,

So You wrote Your own driver to the ADV7180 (or similar)? And with this driver it is all working fine?

I meant the location of custom driver for iMX 8M Mini could be under drivers/media/platform/mxc/capture/ if it was a completely new one. I did develop/port custom driver(s) for iMX 8M Mini and place under the mentioned location : https://community.nxp.com/t5/i-MX-Processors/Custom-camera-driver-adaptation-on-iMX8M-Mini/m-p/10907...

Effectively, the one maintained by Freescale/NXP (https://source.codeaurora.org/external/imx/linux-imx/tree/drivers/media/platform/mxc/capture/adv7180... is an older one (it mainly supports adv7180) and has dependency on IPU (in menuconfig). 

The upstream driver developed/maintained by Analog-Devices (https://source.codeaurora.org/external/imx/linux-imx/tree/drivers/media/i2c/adv7180.c?h=lf-5.10.y) seems more generic and supports wider range of decoders (including one with MIPI-CSI2 outputs). I have also successfully used this driver for ADV7280-M in another platform (Nvidia Jeson) with small adaptation.

Btw, I tested the later on the EVK and with the ADV7280-M :

 

root@imx8mmevk:~# dmesg | grep adv7180
[    6.827569] mxc_mipi-csi 32e30000.mipi_csi: Registered sensor subdevice: adv7180 2-0021
[    6.843251] adv7180 2-0021: chip found @ 0x21 (30a40000.i2c)

 

I think that the /dev/video0 is always there as it is populated by the presence of csi-bridge node :

 

root@imx8mmevk:~# v4l2-ctl --list-devices
i.MX6S_CSI (platform:32e20000.csi1_bridge):
        /dev/video0

vsi_v4l2dec (platform:vsi_v4l2dec):
        /dev/video2

vsi_v4l2enc (platform:vsi_v4l2enc):
        /dev/video1

 

and if the mipi-csi interface is well configured (number of lanes, hs-settle, clk-settle, ...) as well as well connected to the output of the decoder, you could obtain the image data :

 

 

root@imx8mmevk:~# v4l2-ctl --list-formats-ext -d /dev/video0
ioctl: VIDIOC_ENUM_FMT
        Type: Video Capture

        [0]: 'UYVY' (UYVY 4:2:2)
                Size: Discrete 720x576
                        Interval: Discrete 0.033s (29.970 fps)

 

I believe that at this step, the ADV728x-M is ready to send data out on its MIPI-CSI interface. The rest would be to adapt the capture driver (mxc_mipi_csi.c, mx6s_capture.c) on the SoC side to receive the output data format of the decoder correctly.

Best Regards,
K.

Hi @KubaACO,

I would say this one : https://source.codeaurora.org/external/imx/linux-imx/tree/drivers/media/i2c/adv7180.c?h=lf-5.10.y , seeing the list of supported devices include yours :

#ifdef CONFIG_OF
static const struct of_device_id adv7180_of_id[] = {
	{ .compatible = "adi,adv7180", },
	{ .compatible = "adi,adv7180cp", },
	{ .compatible = "adi,adv7180st", },
	{ .compatible = "adi,adv7182", },
	{ .compatible = "adi,adv7280", },
	{ .compatible = "adi,adv7280-m", },
	{ .compatible = "adi,adv7281", },
	{ .compatible = "adi,adv7281-m", },
	{ .compatible = "adi,adv7281-ma", },
	{ .compatible = "adi,adv7282", },
	{ .compatible = "adi,adv7282-m", },
	{ },
};

MODULE_DEVICE_TABLE(of, adv7180_of_id);
#endif

 

But it might requires certain tuning depending on the input video format (PAL/NTSC) as well.

Best regards,
Khang.

Hi @KubaACO ,

But this driver is not creating any /dev/videoX (it's not supposed to).

Is it possible to share you device-tree and more log (dmesg), please ?

Hi @KubaACO ,

There's another driver probably in your expected location : https://source.codeaurora.org/external/imx/linux-imx/tree/drivers/media/platform/mxc/capture/adv7180...

/* This function attaches this structure to the /dev/video0 device.
	 * The pointer in priv points to the adv7180_data structure here.*/
	adv7180_int_device.priv = &adv7180_data;
	ret = v4l2_int_device_register(&adv7180_int_device);

You can also give it a try.

Best Regards,
K.
