I just dont know what happen I just came from my work , suddenly no internet and wifi signal from my R4 , check it though serial and no output , toggle both mmc and nand with same issue , sim led on , wan eth and lan 1 leds both on…change my power supply to usb c pd with the same issue nothing at all…
I have similiar problem, try to disconnect al things beside board. i see that You don’t have g led light up as mine.

did it work again when you disconnected all the cards?

Nope, i have three so i can compare voltages, but i think that cpu died.

Similar cases here:
@sinovoip and @simon respond like this:
- You can contact our sales or [email protected] and ask for support.
4 dead boards already damn, hoping the board I ordered doesn’t end up dying

I think it’s faulty DC adapter. Always use USB-PD when possible, it’s much more safe for the board.
Nope, all voltages are ok, cpu died i belive. I’ve used dell original psu usb-c.
got a reply from banana pi customer service. I told them the cards (FM350 , Asiarf 7916) and sfp I’m using which are 1.25G Huawei SFP module since my switch was capable of SFP only.Does it means we need to use 10G modules only in our R4 ?
Nope, sfp slots works with 1gig, 10gig and 2.5gig i’ve persolanly tested. Problem with dying is more complicated.

Mainline openwrt is different, openwrt mainline is the master branch and is non stable and the other builds are stable like 23.05 but both are official
Every day, I learn more.
It is a bit off topic but I can not call the openwrt version from firmware-selector mainline?
And I have to call the version from bananapi “official”.
This feels wrong …
Banana pi is basically official openwrt with MTK sdk in it, in reality all OpenWRTs are pretty muc official, only RooterOS etc are forks with heavy modifications
So, second try,
I just read your comment, not the whole chat.
There are differend versions of openwrt. BananaPI has there own special version.
I’m not up-to-date about the drivers of any version! But history shows that at the beginning of the hardware release, the Banana Pi OpenWrt version could be seen as an attractive option. This is because it has the driver (for their specially recommended hardware) implemented.
With the “natural evolution” of this OpenWrt version → (https://firmware-selector.openwrt.org/), the game changes because it supports more hardware (like your huawei SFP). This is already happened with R3 → I didn’t think someone is still using the Banana Pi version for the BPI-R3 for any advantages.
So, with this information, you shouldn’t be surprised about the answer. The documentation (Getting Started BPI-R4 | BananaPi Docs) shows only 10G for R4 SFP:
If I were Banana Pi support, I would ask you, “Are you using our software and our recommended hardware? If not, you might encounter compatibility issues.”
For debugging with bananapi, I would may use there Version!
