Description Johan Hovold 2022-05-27 08:15:41 UTC
The Qualcomm sc8280xp Compute Reference Design (CRD) has a QCNFA765 WiFi/BT module but there's currently no matching board file in ath11k-firmware:

  ath11k_pci 0006:01:00.0: chip_id 0x2 chip_family 0xb board_id 0x8c soc_id 0x400c0200
  ath11k_pci 0006:01:00.0: failed to fetch board data for bus=pci,vendor=17cb,device=1103,subsystem-vendor=17cb,subsystem-device=0108,qmi-chip-id=2,qmi-board-id=140 from ath11k/WCN6855/hw2.0/board-2.bin

lspci:

  0006:01:00.0 Network controller: Qualcomm QCNFA765 Wireless Network Adapter (rev 01)
          Subsystem: Qualcomm Device 0108

Note that the device-id matches one of the ids for the board files requested here:

Comment 1 Kalle Valo 2023-03-17 09:50:47 UTC
I now updated board-2.bin which contains a board file but for Lenovo X13s variant:

https://github.com/kvalo/ath11k-firmware/commit/fa6886ff0d62e9d84e5985e01fc75da0157c2887

I don't know yet if that should be used also with the sc8280xp CRD.

Is there any more information about this CRD products? For example a link to a product page would be really helpful
Comment 3 Johan Hovold 2023-03-20 12:48:49 UTC
The CRD is Qualcomm's "compute" reference design for sc8280xp (i.e. a laptop similar to the Lenovo X13s).

You can probably find more details inside Qualcomm, but here are a couple of related links:
