Hi, I would like to know how I can change the i2c bus number where to connect the imx219 sensor? this one seems to connect on bus 6 for some reason? I check the tegra210-porg-plugin-manager.dtsi and tegra210-camera-rbpcv2-imx219.dtsi without luck. I would like to replace i2c bus on bus0. I know my I2C device is working fine since I can fully access it through /dev/i2c-0 with i2cdetect tool. Regards, Jérôme ---

You may need to check the context of the /proc/device-tree that was modify exactly as yours. You may need apply “the fix the dtb update failed” from below link. [https://elinux.org/L4T\_Jetson/r32.3.x\_patch](https://elinux.org/L4T_Jetson/r32.3.x_patch) ---
