Using l4t_create_default_user.sh, can I turn off the display lock and adjust the screen off time as follows?
Can I set each nano network address to be multiplexed using l4t_create_default_user.sh? (E.g. using loops in a script)
No, it does not have this function. This is not an official tool. But just a tool for debug.
What is the customizable scope with l4t_create_default_user.sh?
You could add anything to this script if you want.
FYI, the script is using qemu to run commands to create users and groups. If you know the command used for setting things like display lock defaults, then you could create your own similar script. The trick is that you must know the command. A copy of the user create script, but designed to run other custom commands, could work.
Create the user account using oem-config and then clone out the system image. After then, use this system image to flash your board, and it may have the account you set previously.
I found the following information on the jetson linux developer site.
However, this seems to be done right after flashing. Does this mean that what you do in this process can be added when making a mass flashing blob?
If first boot has been completed prior to cloning, then yes, this is included in the cloned image, and in any system flashed with that image. You could go even further, and complete “sudo apt update” and “sudo apt-get upgrade”. You could install custom software too if desired, or standard NVIDIA optional packages, such as CUDA.
Some content may be tied to the specific Jetson, e.g., some network software might look for a specific MAC address, and it would be an error to transfer this to all Jetsons during flash (this would be rare though).
The l4t_create_default_user.sh could be modified to do nothing more than change the created user’s password (assuming the account already exists, then you wouldn’t want to try to create it again), and perhaps log the password for documentation to ship. Then setup would be complete, but each Jetson would have its own password, and no longer be considered a “default” password (it would be illegal to set a default password when shipped to California).
I have not used mass flash though, so I can’t claim to have tested the mass flash variation of this.
I have not explored this much, but on a running Jetson, you might be interested in: /usr/sbin/nv-oem-config-firstboot /etc/init/oem-config.conf /usr/share/doc/nvidia-l4t-oem-config/
