Hi, Balena team!
Did you have a chance to check this board? https://www.khadas.com/vim3
It seems @gabolema has gotten Balena running using a Jetson Nano image (?).
Here: Getting below error for wifi-connect on jetson nano - #8 by builder555
Would be great if anyone else could confirm. Seems like a great board, and Khadas Vim2 goes for real cheap on Amazon.
