I sounded new to openwrt, I have a ubiquiti AC HD, after many hours I managed to install the system on it, but the storage remained at 8mb.
The nand memory has 233mb and it is possible to use this space ???
The current minimums are 8/64 (for 23.05). 24.10 (in release candidate phase, not yet officially released as stable) increases that to 16/128. You've got quite a while before 32/256 will be a limiting factor (I can't say how long, but probably to the point that it won't make sense to be using wifi 5 devices).
If your problem is solved, please consider marking this topic as [Solved]. See How to mark a topic as [Solved] for a short how-to.
Thanks!
