This would depend on interest from Olimex as well. We haven’t started the conversation yet because the FreedomBox images for A64 OLinuXino have not been published yet. I think, however, there are no blocker for this now.
Olimex Teres A64 laptop is based on A64 OLinuXino, therefore imagine they are happy to have another consumer product based on the A64 platform. The only problem, I see with the A64 is the missing SATA port and no USB 3.0. I am not sure if this is a problem for people wanting to have the FreedomBox as a tiny NAS like system.
Slightly bigger issue is having only a single USB port. Despite it having 4 64 cores etc, the A64 chip is designed for tablets it seems. For a majority of our users, this is not a concern. Especially given eMMC gives good performance.
