Thank you very much for your responses, it totally make sense. I will try to build it myself, tho I have never done that, and my knowledge is very limited. I'd love to help one day, but this really is beyond what I can offer, for now.
Are there no more update coming for the armsom-w3?
I was planning to put the new ubuntu with KDE that showed up one month ago, and since a few days, it is not available anymore, there is only the trixie minimal.
I was just wondering if it was normal or if the support was dropped for the armsom-w3 board.
