thanks for your answer.
As you know I’ m not a dev, sharing my built images (on a dedicated web site is not a problem :-) but provide a support is not thinkable.
I can continue to report the working and not working images, packages, and so on.
Feedback from users is a part of software development.
I report the working situation, images on the odroid forum for the n2, m1 and c4.
Unfortunately nobody created a manjaro arm post for the Odroid c2 in the dedicated odroid forum section.

Missing images (I build for years) on the manjaro web site download page are the n2 and c2, are those images necessary ?
