Jetson Orin Nano Developer Kit Can‘t Use I2C0 or I2C1

Jetson Orin Nano Developer Kit

I am using the Jetson Orin Nano Developer Kit with the 5.1.1 version of the SDCard image. I need to use either the IIC0 or IIC1 interface, so I tested these interfaces using the iic-tools tool and captured waveforms using a logic analyzer. However, I found that no signal was captured by the logic analyzer regardless of whether I used the commands “i2cdetect -y 0” or “i2cset -f -y 1 0x51 0x00 0xff”.

is it correct that the IIC1 interface corresponds to pins 3 and 5, and the IIC0 interface corresponds to pins 27 and 28 on the Jetson Orin Nano Developer Kit?

in sysfs, pin 3 \ 5 is i2c7 bus, not iic1. all right
