I have been testing the wcn6855 support on the Qualcomm SM8450 platforms (Lantronix HDK8450). Loading firmware from linux-firmware doesn't work. It has Qualcomm WCN6856 chip onboard. Kernel: 5.18-rc7 + PCIe patches + driver to boot up the WCN6856. Distro: Yocto + meta-qcom Reproducible: each time. root@qcom-armv8a:~# uname -a Linux qcom-armv8a 5.18.0-rc7-00052-g1355d64bc314 #878 SMP Mon May 16 16:25:45 MSK 2022 aarch64 GNU/Linux root@qcom-armv8a:~# lspci -mnn 00:00.0 "PCI bridge [0604]" "Qualcomm [17cb]" "Device [0110]" -p00 "" "" 01:00.0 "Network controller [0280]" "Qualcomm [17cb]" "QCNFA765 Wireless Network Adapter [1103]" -r01 -p00 "Qualcomm [17cb]" "Device [0108]" 0001:00:00.0 "PCI bridge [0604]" "Qualcomm [17cb]" "Device [0110]" -p00 "" "" root@qcom-armv8a:~# md5sum /lib/firmware/ath11k/WCN6855/hw2.1/*.bin 460fbd5ddc57b3d2efbf1ca976f78b90 /lib/firmware/ath11k/WCN6855/hw2.1/amss.bin 88b3a4fbde8cab4493f0060ae3b5dee3 /lib/firmware/ath11k/WCN6855/hw2.1/board-2.bin 7fd1c2337b0b6502588d3141e205e735 /lib/firmware/ath11k/WCN6855/hw2.1/board.bin d1460fc1c4595d0d22f82d5baeaabbd8 /lib/firmware/ath11k/WCN6855/hw2.1/m3.bin f67be83659c790fe15d1e42af501e9fa /lib/firmware/ath11k/WCN6855/hw2.1/regdb.bin root@qcom-armv8a:~# dmesg | grep ath11k [ 2.794913] ath11k_pci 0000:01:00.0: Adding to iommu group 1 [ 2.802754] ath11k_pci 0000:01:00.0: BAR 0: assigned [mem 0x60400000-0x605fffff 64bit] [ 2.810980] ath11k_pci 0000:01:00.0: enabling device (0000 -> 0002) [ 2.818429] ath11k_pci 0000:01:00.0: MSI vectors: 1 [ 2.823473] ath11k_pci 0000:01:00.0: wcn6855 hw2.1 [ 3.778991] ath11k_pci 0000:01:00.0: chip_id 0x2 chip_family 0xb board_id 0xa7 soc_id 0x400c0210 [ 3.788036] ath11k_pci 0000:01:00.0: fw_version 0x110f0c35 fw_build_timestamp 2022-03-30 09:05 fw_build_id QC_IMAGE_VERSION_STRING=WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.7 [ 3.812838] ath11k_pci 0000:01:00.0: 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=167 from ath11k/WCN6855/hw2.1/board-2.bin [ 14.101999] ath11k_pci 0000:01:00.0: failed to wait board file download request: -110 [ 14.110098] ath11k_pci 0000:01:00.0: qmi failed to load bdf file [ 14.116308] ath11k_pci 0000:01:00.0: failed to load board data file: -110 The same behaviour can be reproduced with each firmware version from ath11k-firmware repo.

Interestingly enough the chip_id differs between these firmware versions.

Dmitry mentioned in the ath11k list: The devices I have here use the following board IDs: bus=pci,vendor=17cb,device=1103,subsystem-vendor=17cb,subsystem-device=0108,qmi-chip-id=2,qmi-board-id=167 bus=pci,vendor=17cb,device=1103,subsystem-vendor=17cb,subsystem-device=0108,qmi-chip-id=2,qmi-board-id=140
Note, there are two different issues: - missing board files - inability of the firmware to load the board file, as shown by the following lines: [ 14.101999] ath11k_pci 0000:01:00.0: failed to wait board file download request: -110 [ 14.110098] ath11k_pci 0000:01:00.0: qmi failed to load bdf file [ 14.116308] ath11k_pci 0000:01:00.0: failed to load board data file: -110

This report is about missing board file for Lantronix HDK8450. Also don't try firmware or board file releases from outside of linux-firmware or my git repo[1], they are completely unsupported in ath11k. [1] https://github.com/kvalo/ath11k-firmware
