It more or less still depends on the companies that create the bin blobs and proprietary SoC software (just check the bin blob tar ball to see the amounts … it’s a lot. Maybe not all the stuff is needed, but that’s another story).
Will all those different companies update their different software if Android/the API changes? Or will their hardware be to old and they will not care anymore due to R&D costs and the need to sell new stuff?
There is nothing FP can do. The only thing that we can hope (and that is something that makes project ara still interesting) is that Google makes the Android APIs for the modules so clean that most bin blobs will work for a long time.
I don’t believe it, but we will see. Maybe the APIs are “stable” enough already?
Maybe some FP insider info could help here to understand how critical this is issue is. Are bin blobs a problem between Android versions? Or is this not a problem?
