How to use other GPIO pins as I2C in Jetson Nano?

I know in Raspberry Pi, I can use other GPIO pins as I2C by adding

dtoverlay=i2c-gpio,i2c_gpio_sda=23,i2c_gpio_scl=24,i2c_gpio_delay_us=2

to /boot/config.txt.

Is there a way to use other GPIO pins as I2C in Jetson Nano?

hello Hongbo-Miao,

you may refer to [url]https://www.jetsonhacks.com/nvidia-jetson-nano-j41-header-pinout/[/url].
please access Jetson Nano Pinmux spreadsheet via Jetson Download Center, for example, you could check I2C2_SCL and choose the type in the customer usage column.
suggest you also check Jetson Nano Developer Kit 40-Pin Expansion Header Configuration for the steps to customize the pinmux.
thanks
