Getting Started - Instructions does not match with current image?

Hello All,

I just got a Nano and I started following the instructions in the course. However, there is not way that it works with the latest flash image. When I tried to starts as suggested using only power and USB cable there is nothing in 192.168.55.1:8888

Actually, after many minutes I decided to stick a HDMI and there is some activities (anacron). Once activity stops I reboot.

So I tried to use GUI. Had accepted the terms, created an user account and updated Ubuntu.

STILL no USB network nor a USB device present.

Here is some logs:

from my desktop:

Thanks in advance for any help.

I guess I had the wrong image. I had the " Jetson Nano Developer Kit SD Card Image" from:

I am not sure the difference but NVIDIA could make this information clarified for users. At the particular page above it could have a warning or a note.

Hi vamarc,

From “Getting Started With Jetson Nano Developer Kit” page, the Download SD Card Image is the latest Image, r32.4.2.
Can you flash and boot success now?

Yes, thanks. As I said I initially had flashed the Developer Kit which does not have the Jupyter Notebook server; therefore, I could not follow the NVIDIA Nano course. All good now. Thanks Carol.
