Thanks Werner for your support. I did make a copy renamed it and changed the name inside too. This image also works okay. one thing i did differently was to use tritium-h3 as base because i felt that it represented the hardware more accurately(please correct me if im wrong)
I have a few queries:
1. How can i test that all hardware is working correctly, if not then what should i do to correct them.
2. the build currently takes more than an hour to complete. Is there any way to speed this up?
3. What more i should do so that board could be added to armbian build config. Im willing to put more work into it.
Thanks again for so much help.
