iMX8MP MIPI-CSI2 Problem with ADV7280 and Camera

[brky06]

Hi,

In our custom board, we got a problem with getting analog video from MIPI-CSI-2 lane and ADV7280 Chip. We have arranged the device tree according to our custom board, where we have used adv7180.c since iMX8MP does not have adv7280.c driver. I have tried all the suggested solutions and examined all the related issues on nxp communities, but none of them helped in our case. We simply can't make the connection between adv7280 and mipi-csi, although the chip is found by the system. Below, you can see the related part of my dts file and dmesg. The error that we have get can be seen below as well.

The important part of the dmesg is

On demoboard, here instead of subdev_notifier_complete, we should have got the 

adv7180 ==> mxc-mipi-csi2.0 connection, but we can't get it. It works fine with demoboard using ov5640.

When we try to use the gstreamer, we can't get the video on screen and we get the following error:

A few things to try:

1. Did you set the input channel for your video correctly? The chip has multiple channels. I had to add some code to enable some v4l2-ctl IOCTL to switch between channels.
2. Press CTRL-C to stop the gstreamer launch and try to run the gst pipeline again right after to see if the pipeline rolls or not. We had issue that the pipeline would not roll for the first time. It seems to have something to do with some clocks turned off by power management and only become active after the streaming is on causing issues. 

good luck.

[zibo_zhao]

We are using the same solution MIPI-CSI -> ADV7280-M. Any known working solution yet? Thanks!

[petero5]

Hi @zibo_zhao
Did you manage to find a solution to "mxc-mipi-csi2.0: is_entity_link_setup, No remote pad found!"?
Thank you, Peter

[zibo_zhao]

No, we have not yet. we did the patch for goko_gr so the warning is gone. But still have not tried the Video part yet since we have not got our board back yet.

[zibo_zhao]

BTW, we are also using 5.15-kirkstone
@nxp support, please give some advice. Thanks!

[petero5]

Also getting "mxc-mipi-csi2.0: is_entity_link_setup, No remote pad found!"
What was the solution please?
NXP i.MX Release Distro 5.15-kirkstone
compatible = "adi,adv7280-m";

[Goko_gr]

Hi @Dhruvit,

We have already tried the solution that you have recommended 2 weeks ago, and it makes the

created link [adv7180 1-0020] => [mxc-mipi-csi2.0]

connection. The correct usage of it is as follows.

static int adv7180_link_setup(struct media_entity *entity,
struct media_pad const *local,
struct media_pad const *remote, u32 flags)
{
return 0;
}

static const struct media_entity_operations adv7180_entity_ops = {
.link_setup = adv7180_link_setup,
};

You must add the last struct in order to work.

However, now the problem is we don't get any video output from the camera with a gstreamer command. The above addition connects the linkage between adv and mipi, but i think adv7180 still don't think porperly. The command we use is

gst-launch-1.0 v4l2src device=/dev/video3 ! video/x-raw,width=720,height=240 ! queue ! fpsdisplaysink sync=false

I have added prints in all of the functions in adv7180.c, and i think the problem is we don't enter the required functions in adv7180.c driver. I tried to fix it by looking the ov5640.c driver, since it is the default working driver, but i have not found any solution so far. For example, we can not enter

static v4l2_std_id adv7180_std_to_v4l2(u8 status1)

static int __adv7180_status

static int adv7180_querystd

these functions.

So, to make it brief, all we asking from you is that stable and working adv7180.c driver which works perfectly with the iMX8MPlus. If we somehow get a camera view , it will be enough for us to move on. Updated adv7180.c driver would be helpful. Any help will be greatly appreciated.

[Dhruvit]

Hi @brky06,

I have sent you an email regarding the issue. Please refer to the same.

Thank you.

Best Regards,
Dhruvit.

Hi @Dhruvit 

I have the same issue:

mxc-mipi-csi2.0: is_entity_link_setup, No remote pad found!

Could you share the solution with us too please?

Thanks

[eduardo3]

This is what we have done with the imx8x (imx8qxp). May or may not help in your case.

Hi @Dhruvit 

We are having the same issue:

Would you be able to share the solution with us too please?

Thank you

We have got definitely the same problem. In addition, the people we have worked with have been encountered with the same problem for a long time with MIPI and ADV7280, but none of us got any answer from NXP yet. Any help would be very useful. Thanks.

[Maruti]

Hi,

In our custom board, we got a problem with getting analog video from MIPI-CSI-2 lane . As you mentioned earlier we also got the same error "mxc-mipi-csi2.0: is_entity_link_setup, No remote pad found! " .
And also the error is solved but when i give the gst command the result is below :
root@imx93-iwg50m-osm:~# gst-launch-1.0 v4l2src device=/dev/video0 ! videoconvert! videoscale ! video/x-raw, width=360, height=240,framerate=25/1 ! autovideosink sync=false

Any help to solve this issue will be highly appreciated. Thanks for your help in advance.

[KimberlyCarvajal]

Hi Maruti,

Your log indicates that the color formats of the input and output are different, this mismatch won't allow to capture the buffers
[ 1487.989391] input fmt YUV4
[ 1487.992371] output fmt YUYV

The adv7280 works with the YUY2 (YUYV) format which looks that is not implemented in the isi source formats.

 Also there is a missmatch on the resolution you are trying to capture
[ 1487.995314] mxc-isi 4ae40000.isi: input_size(720,288), output_size(360,240)

Looks like the ADV7280 is configure to capture NTSC interlaced 720x288 and you are trying to capture 360x240.

Hi @KimberlyCarvajal 
Thhanks for your response 

Any solution from your side ? Thanks in advance 
Regards

Maruti

[KimberlyCarvajal]

Hi @Maruti,

Yes, RidgeRun has developed this support before for the i.MX8 and other NXP devices. It is require to modify the files drivers/staging/media/imx/imx8-isi-cap.c and drivers/staging/media/imx/imx8-isi-fmt.c by adding the YUY2 colorspace to the isi in/out formats structs to match the hw capabilities.

The modifications can be done on your side, a new kernel image requires to be built and installed, if you require RidgeRun to provide this support, please contact us at support@ridgerun.com, you can check more RidgeRun information at:

• www.ridgerun.com

Hi @KimberlyCarvajal 
Can i get  patch for the modifications that you done on drivers/staging/media/imx/imx8-isi-cap.c and drivers/staging/media/imx/imx8-isi-fmt.c files.

[eduardo3]

I had to modify the driver to avoid that size issue. See if this helps you.

Hello @eduardo3 

Thanks for your resposnse
I have modified the driver code as in your patch but the output has no difference. can you pls share your dts changes .
