Thank you for the documentation. I read them and configured the values

Thank you for the information. At present, I haven't tried it on any
board as I am using it as Sandbox but I have BeagleBone Black and
Raspberry Pi 3B.

Yes, I am trying to execute it as Sandbox and while executing through
sudo please find the information given below:

sudo ./barebox

add stickypage initially unbacked by file

I am doing ping but it doesn't have any dns entry and route to resolve it.

Please let me know for any other information.
