I just got a new Jetson Orin Nano Super, after followed guide to upgrade firmware to 36.4.3 and boot up JetPack 6.2 from SD card. sudo dmesg | grep i2c got following message

[    0.155997] i2c_dev: i2c /dev entries driver

After connected i2c oled display, I cannot find any device from i2cdetect.

I am pretty new on this system, any help is appreciated.

Hi,

How do you connect to the i2c display?
Could you describe in detail?
Also please refer to the related topics in

Thanks, the problem has been addressed. The i2c I am using is on bus 7 instead of bus 1.
