How to check cam_i2c_scl on the software is which group /dev/i2c-?

你好,我在使用jetson orin nx的mipicsi接口,我把相机的iic接在了cam_i2c上,我想知道实际软件上使用的时候是哪一组 i2c-*? 我在设备树中配置时如何区分,是 i2c@3180000 ?
还有mipicsi-*的序号在设备树中如何区分,我使用的是csi0的4lane,
我已经参考了这个链接,但还是不太清楚,希望你能解答一下,谢谢,我使用的sdk是35.5.0版本的。

hello Towe_Roll,

it’s i2c3.
you may see-also Jetson Orin NX Series and Jetson Orin Nano Series Pinmux.
or… by checking TRM. I2C3, 0x03180000
software side started from 0, you’ll see its aliases with i2c2 = &cam_i2c;
