Are the banana pi boards able to run a mainline kernel or close to it? I have a memory of getting real close to buying one of those, and then reading a comment on HN about having to run their Frankenstein setup
Given the similarities in port layout (just missing a HDMI and USB3 header), and that the case is nearly identical, I would guess that this router probably is a custom run of the exact same BananaPi board without those headers. Both also use MiniPCIe in 2026, which is a bit of an odd decision.
The page linked above contains links to their bootloader and Linux kernel tree (6.1 apparently), so chances are rather low.
Depends on the board.
Btw, I don't see anything about mainline in TFA, did I miss that?
FWIW there is also "OpenWrt mainline" and "Linux mainline"; OpenWrt carries a whole bunch of things on top of Linus' tree but I'd still call that "mainline".
