Amazing you'd suggest an R4 given it's support is fundamentally broken. Sinovoip's OEM build is an ancient 21.02 one. Whereas in the official one wifi is completely broken, working SFP is pure luck as "many" modules (all four fiber ones I've got here) on kernel 6.6 either don't show at all or just fail to come up. This was known to OpenWrt's mediatek maintainer who preferred to "spot and fix" it on the go: https://github.com/openwrt/openwrt/commit/6257ea018a7d5b8d4b68b1057a08555866628b4c#diff-9fc0744d11dcf8c439cb54cdfbeb91dc46b7bb1dfc10f3281d843b57e3b31468 https://github.com/openwrt/openwrt/commit/6257ea018a7d5b8d4b... Meanwhile there are about two kernel devs working on mediatek in their free time who've only begun upstreaming R4 support, eg. Frank W.'s DTS parts… for kernel 6.14. (The other dev is Eric. W.) To quote Frank W.: "The patches i posted are mainly patches adding basic support,only slightly changed to get accepted for mainline. There is no network part yet,also no sfp. Maybe i add sfps in next round,but without full network part (which is much work) it will not work." ( https://forum.banana-pi.org/t/bpi-r4-and-sfp/16945/330 https://forum.banana-pi.org/t/bpi-r4-and-sfp/16945/330 ) Edit: The R4 also needs a soldering mod for certain SFP modules, and prior board revs have resistors that break SFP if NVMe is present (I'd say: sure to get 1.1, but Sinovoip originally shipped that rev broken as well, and didn't increment to 1.2 for the fixed ones).
