Thanks, I am working on that but having trouble finding information on how exactly that is done. I’m continuing to work on it. Can you suggest any resources?
While you’re here I want to ask if you can provide any more information on the fact that the 2020 image simply does not work, and neither does the buildroot guide here: https://www.96boards.org/documentation/som/tb-96aiot/build/buildroot.md.html
Both result in a non-booting board with this output over UART:

I have followed the buildroot guide exactly and everything works, after adding the ./build.sh step you mentioned in another thread, but the resulting image just doesn’t boot. I want to supply more information but I don’t think I can because like I say, it all goes smoothly up until failed boot with the message above. Can you please investigate and update the document?
I have tried different buildroot guides with varying levels of success, such as this based on a different board and buildroot repo:
As long as the buildroot guide is broken, editing dts files won’t do any good.
