Hello,
Few days ago, I found that I2C doesn’t work.
I installed [Jetson Nano – Run on USB Drive]

Is that related? How can I fix it?

Detail is below.
Thank you for your help.

$ sudo i2cdetect -y -r
Error: No i2c-bus specified!
Usage: i2cdetect [-y] [-a] [-q|-r] I2CBUS [FIRST LAST]
i2cdetect -F I2CBUS
i2cdetect -l
I2CBUS is an integer or an I2C bus name
If provided, FIRST and LAST limit the probing range.

$ sudo i2cdetect -l
i2c-3 i2c 7000c700.i2c I2C adapter
i2c-1 i2c 7000c400.i2c I2C adapter
i2c-6 i2c Tegra I2C adapter I2C adapter
i2c-4 i2c 7000d000.i2c I2C adapter
i2c-2 i2c 7000c500.i2c I2C adapter
i2c-0 i2c 7000c000.i2c I2C adapter
i2c-5 i2c 7000d100.i2c I2C adapter

Why do you say that I2C doesn’t work?
You need to pass a bus number (for example, 1) to the first i2cdetect -y -r command.

Thank you for your quick reply.
Because PiOLED display doesn’t show any information.
It’s broken

I did correct command I2Cdetect, I2C works.

sudo i2cdetect -r -y 1
