Help me, hava a nice day!

I have WCN7850. I compiled the kernel with CONFIG_ATH12K and followed the instructions on the wiki for the firmware, but I'm also getting “failod to fetch board data” (and in my case it's also failing to load the firmware, too).

One issue per bug report, please. I will hide the other reports because otherwise it will be impossible to track this bug. More info here:

https://wireless.wiki.kernel.org/en/users/drivers/ath12k/bugreport

xiaoniu, what device or QCN9274 board are you using? That's important for finding the correct board file.

I have the same bug. I've built a homeserver using a "Wallys DR9274-5G&6G" M.2 card. It's using a QCN9274 chipset in split configuration, so 2x2 5 GHz and 2x2 6 GHz.

The complete datasheet can be found here:
https://www.wallystech.com/upload/DR92745G6G.pdf

I am using Kernel 6.10.4 on Fedora Server 40.

I have installed ath12k firmware for QCN9274 (since it isn't even in linux-firmware yet!) manually via the official instructions here: https://git.codelinaro.org/clo/ath-firmware/ath12k-firmware/-/blob/main/README.md?ref_type=heads

Firmware is correctly installed under /lib/firmware/ath12k/QCN9274/hw2.0:
- board-2.bin
- firmware-2.bin

Sadly, the wifi card is not found. Any advice on this would be greatly appreciated. Here's my dmesg output:

This is because your device do not have board-id (0xff). And board-2.bin do not have bdf for board-id=255 (0xff). You can encode your bdf to board-2.bin or use directly as board.bin.

Thank you very much. Can you provide instructions on how to do this?

Ronald, did you find a solution?

I have posted several weeks ago on the mailing list as Kalle suggested but got zero response. :(

https://lore.kernel.org/ath12k/7519810f2dc252d430157ee4409f6654@posteo.de/

Is there really no possibility to get this card working?

Ok, no problem! Thanks for the info!

I would still really, really like a solution to my problem. I have built a homeserver and want to use the aforementioned QCN9274 card (Wallys DR9274-5G&6G) as my wifi access point. This bug is now a year old and no solution. :(

"wlpuah" said in comment #7: "You can encode your bdf to board-2.bin or use directly as board.bin." I have asked the mailing list on how to do that but got no response there. :(

If you or anyone else from the ath12k team could take a look at it and supply a short howto here, it would be much appreciated!

Hey there. I'm not from the ath12k-team but had some struggle with my QCN9274-board as well and did a lot of reading and at least found some "tweaks".

To encode bdf to board-2.bin, you would need an individual board-file, preferably from the manufacturer of your board -> Wallys. My humble experience taught me that most board-designers of QCN9274 boards don't have an adjusted board-file (yet) but you could try it with the "standard"-files from the ath12k-developers.

Go to:

https://git.codelinaro.org/clo/ath-firmware/ath12k-firmware/-/tree/main/QCN9274/hw2.0

and download the "board-2.bin". Since October, this is now also part of the official "linux firmware"

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/ath12k/QCN9274/hw2.0?h=20241017

but Codelinaro is a bit more recent. Anyway, use the "ath12k-bdencoder" from the qca-swiss-army-knife

https://github.com/qca/qca-swiss-army-knife/tree/master/tools/scripts/ath12k

to extract the board-files from the "board-2.bin". The board files look like this -> bus=pci,qmi-chip-id=0,qmi-board-id=*

They have individual IDs at the end, which stand for the band. "1" is for 2,4Ghz, "2" is for 5Ghz and "4" is for 6Ghz.

Take the one you need / want and rename it to "board.bin".

Put "firmware-2.bin", "board-2.bin" and "board.bin" in

/lib/firmware/ath12k/QCN9274/hw2.0/

and reboot your system. That's how I got my Emwicon WMX8402 going... still not working with all the features it promises, somehow using kind of the wrong regdb and still many bugs but at least it's pretty stable. I owe the guys from quic big time, they're doing a really good work!

Thanks a lot! Tried it, to no avail.

1. Get "board-2.bin" and "ath12k-bdencoder" as described above.
2. ./ath12k-bdencoder --extract board-2.bin
3. Find out that from the extracted files, there is none that can be applied to my split-phy card, since it uses both 5 GHz and 6 GHz (2 channels each).
4. Resist urge to throw card in trash.

There simply seems to be no board.bin for split-phy cards yet, not even a "standard" one from the ath12k team.

My board is also advertised as dual-band or more exactly wide-band, unfortunately I have to decide for one band, at least for now.

Did you try with only 5 Ghz (for example), did that work?

And did you contact Wallys for an adjusted / individual board file?

I tried with only 5 GHz (board id 2). Strangely, nmcli reports the connection as "active", but there is no SSID being generated (checked with my smartphone and a wifi scanner app).

Do you also have the "Invalid module id 2" line?

It could be fine (because we're intentionally using the wrong board.bin), or it could be a difference between your card and mine that prevents me from doing the same trick that you did.

It would be cool to use at least 5 GHz as a workaround, but it's no replacement for a correct board.bin from Wallys.

> And did you contact Wallys for an adjusted / individual board file?

Yes, I have contacted someone from Wallys today!
Waiting for a response.

Hopefully Wallys can provide the correct board.bin for their card (maybe even for all of their complete Wifi 7 lineup!). With that, it should be easy for the ath12k team to make all of their cards work out-of-the-box on every Linux distribution worldwide.

We could then recommend them as "the" standard manufacturer for Linux Access Points.

I got almost the exact same output as you

and mine works fine with hostapd (far from perfect, like I said before, but stable). So maybe it's something in your config? But that should not be discussed here.

Greetings

Thanks, I'll look into it!

The difference between our setups will be that I'm using NetworkManager and you're using hostapd. So the *workaround* not working for both of us seems to be a config problem on my end.

So to sum it up, it seems we can use Wifi 7 cards with QCN9274 chipset in AP mode, when using the manual steps described here in comment #14. But only with a single frequency (2.4 GHz OR 5 GHz OR 6 GHz).

Reason why we can't use split-phy cards is because of lacking board.bin for split-phy cards.

Best would be to have a board.bin from the card manufacturer, but second best option would be a default board.bin from the ath12k team.

The ath12k team could provide a board.bin for split-phy configuration to solve this problem and enable the workaround for cards like mine.

Would this be possible to do, @ath12k team?
