I'm getting the following error with v5.17-rc2 kernel and a WCN6855 card: chip_id 0x2 chip_family 0xb board_id 0xff soc_id 0x400c0200 failed to fetch board data for bus=pci,vendor=17cb,device=1103,subsystem-vendor=105b,subsystem-device=e0b8,qmi-chip-id=2,qmi-board-id=255 from ath11k/WCN6855/hw2.0/board-2.bin However, I have another card working fine with this data: lspci: Network controller [0280]: Qualcomm Device [17cb:1103] (rev 01) Subsystem: Foxconn International, Inc. Device [105b:e0ce] dmesg: chip_id 0x2 chip_family 0xb board_id 0xff soc_id 0x400c0210 Apparently, only subsystem ID is different. I'm using this firmware for both, most recent commit: https://github.com/kvalo/ath11k-firmware This is the info from the failing card: 03:00.0 Network controller [0280]: Qualcomm Device [17cb:1103] (rev 01) Subsystem: Foxconn International, Inc.

Can you tell more about the WCN6855 card? Did you buy it from somewhere separately or is it included in a laptop (what model) etc? This helps to find the board file.
Created attachment 300476 [details] image of the card We received some spare cards from partners to test them and enable support in RHEL, but I haven't been able to find exactly where it came from. Here I attach an image of the card, just in case it helps.
Created attachment 300477 [details] back side image That "2102" in the back might indicate it was manufactured on 2nd week of 2021, maybe?
board-2.bin from this directory should have the correct entry now: https://github.com/kvalo/ath11k-firmware/tree/master/WCN6855/hw2.0
I confirm that it's working now. Thanks!
