I burned “jetcard_nano-4gb-jp451.zip” on a micro SD card and loaded the micro SD card on to my Nano 4GB B01.
I then powered up the Nano 4GB by plugging the USB barrel plug adapter into the USB battery pack.
I proceeded to connect my Windows PC to the Jetson Nano 4GB via a micro USB cable.
Opening the Chrome browser on my Windows PC and navigating to 192.168.55.1:8888 resulted in no response from the Nano 4GB whatsoever.
So I shutdown the Nano 4GB, attached a HDMI monitor, keyboard and mouse, powered back up and observed the Ubuntu Desktop appear on the monitor.
I also noticed a warning that the OS could not create /home/jetson/.config/nautilus because it did not have write permission.
I then proceeded to use the Desktop Terminal, per the Jetracer installation instructions, to setup a Wifi connection with my home WiFi router.
The OS then proceeded to update itself and perform a reboot twice. After each reboot the OS complained that it could not create /home/jetson/.config/nautilus because it did not have write permission. It appears that the “jetson” directory is not accessible for either OS or program reading or writing.
When attempting to install the JetCam and torch2trt Python packages I received a message that they already existed so I deleted both of them and proceeded to reinstall them both following the Jetracer installation instructions. I also received numerous warnings that the files in the “jetson” directory were not readable or writeable due to a lack of permissions.
The Jetracer package installed without issue except for the warning that the installation program could not read or write to the files in the “jetson” directory.
After completing the software installation I proceeded to use the jetracer notebook to run the first example “basic_motion.ipynb” which ran without an issue. I then began example “interactive_regression.ipynb” and was able to view the camera video output, but did not continue beyond that point for the time being.
I guess the “** but not yet fully verified **” warning for the latest jetracer image release for the Nano 4GB should be taken seriously as I have documented above.
