IMX95 and MX95MBCAM bring up issue

[Rathore-pioneer]

Hi,

I am using imx95 evk with 3 mx95mbcam connected via maxim serdes.
when I use default image which was already there in emmc then I am able to capture frames and record the video but when I use an image which is generated from yocto it's not working.
here is error logs for reference:

this image(imx-image-full) is generated with yocto.
It does not have any modification related to camera.
Yocto Image kerenl version is: 6.12.49
Default mmc Image kernel version is: 6.6.20

There is an issue with version 6.12.49.
Downgrade my yocto setup.
I rebuilt the image with version 6.12.20(default emmc0 image version), and the camera is working as expected, similar to the default emmc0 image.

Hi,

Thank you for your interest in NXP Semiconductor products,

First, confirm you have made the proper settings,

1. Selected the appropriate DTB.

imx95-19x19-evk-ox03c10-isp-it6263-lvds0.dtb
imx95-15x15-evk-ox03c10-isp-adv7357.dtb
imx95-19x19-verdin-ox03c10-isp-lt8912.dtb

2. Declared the necessary environment variables.

W=1920
H=1280
RAW=SBGGR16
CAMERA0="/base/soc/bus@42000000/i2c@42530000/max96724@27/i2c-mux/i2c@0/mx95mbcam@40"
CAMERA1="/base/soc/bus@42000000/i2c@42530000/max96724@27/i2c-mux/i2c@1/mx95mbcam@40"
CAMERA2="/base/soc/bus@42000000/i2c@42530000/max96724@27/i2c-mux/i2c@2/mx95mbcam@40"
CAMERA3="/base/soc/bus@42000000/i2c@42530000/max96724@27/i2c-mux/i2c@3/mx95mbcam@40"

3. Confirm gstreamer pipeline with the format that is documented for this camera "format=YUY2"

libcamerasrc camera-name="$CAM_NAME0" ! video/x-raw,format=YUY2 ! queue !

This is a documented reference that was displaying multiple cameras, but you can adapt it to your preview.

Regards
