IMX95 and MX95MBCAM bring up issue

Rathore-pioneer — Mon, 16 Feb 2026 06:45:44 GMT

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:

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

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.
