Issue with Camera Sysfs Entry Not Creating After Modifying DTS for Orin Nano in L4T 36.4.0

Hi @ ShaneCCC,

I have created a custom device tree overlay for our custom carrier board based on the Orin Nano. We didn’t make any hardware changes between L4T 35.4.1 and L4T 36.4.0. Everything worked perfectly with L4T 35.4.1.

However, since JP6.1, the camera is coming under the dtbo, so I modified my DTS file accordingly. After making the necessary changes, the sysfs entry is no longer being created.
Even i2c expander not probing pca9546. But if i added this expander entry in dtb. I2c expander probe getting passed

Could you please assist in resolving this issue? Any insights or guidance would be greatly appreciated.

Hello @pippalla.chakravarthi

Could you compare your device tree against the tegra234-p3767-camera-p3768-imx219-A.dts overlay?

The path is:

./hardware/nvidia/t23x/nv-public/overlay/tegra234-p3767-camera-p3768-imx219-A.dts
