Do you have this issue on older kernels?

I didn't test older kernels, but I have another wifi adapter brand with different vid/pid that uses the WCN6855 and it works fine

Any update on this?

I repeat again: Do you have this issue on older kernels using QCNFA765?

Hi Bagas,

please tell me which kernel version I should check, I don't see the reason why an older kernel should make a difference?
From my point of view the vendor-id/device_id for this hardware is just missing in the firmware.

I've got the 6.0.12 kernel with the same WCN6855 firmware running on another piece of hw from another brand:

It doesn't really answer my earlier inquiries. Again: Using 6.0.12 kernel,
can you reproduce this issue WITH your QCNFA765 device?

I'm sorry for confusion.
The problem persists on both kernel 6.0.12 and 6.2.12

Yeah, in this case the kernel version doesn't make any difference as the
issue seems to be the missing board file for this Silex device in
board-2.bin.

I'll try to find one but most likely Silex only has the correct board
file. Does anyone if Silex has it available somewhere? Also any pointers
to the actual product and support information would be helpful.

I do have the board file available and I am looking to have those integrated into the linux-firmware repository. See also https://lore.kernel.org/all/20240829120037.GB30406@francesco-nb/


$ strings board-2_US_EU_JP.bin | head -1
QCA-ATH11K-BOARD

To be precise, my device is named SX-PCEAX, the one in the title does not exists according to google and to the Silex website, so I assume it is just a typo.

So does that board file work for you when you rename it to board-2.bin
and install it to correct location in /lib/firmware? That's not clear
for me.

Yes, it works fine.

The need is to have the required board support file integrates in the linux-firmware git repository

This is needed to
 - Enable multiple Wi-Fi devices using the ath11k driver in the same system/distribution
 - Have the device working out of the box with any linux distribution integrating the upstream linux-firmware

Any update on this?

I have the files that I received directly from Silex, and from some investigation it seems that I would need to extract some payload out of it using some tool from `qca-swiss-army-knife` (https://github.com/qca/qca-swiss-army-knife/blob/master/tools/scripts/ath11k/ath11k-bdencoder).

At least this is what I understood from some old discussion here, https://lore.kernel.org/all/87lea6m3pc.fsf@kernel.org/

I can provide the whole board-2.bin file or I can extract what's required with the mentioned tools (I never did it).

Just let me know how to move forward.
