Description Dmitry Baryshkov 2022-05-16 16:04:59 UTC

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.

The same behaviour can be reproduced with each firmware version from ath11k-firmware repo.


With the earlier firmware from ChromeOS (https://chromium.googlesource.com/chromiumos/third_party/linux-firmware/+/d233ddd89abe06448070471963a58c0a7da81d79/ath11k/WCN6855/hw2.0) I'm getting the following trace (and
WiFi device probes and works). Interestingly enough the chip_id differs between
these firmware versions.

Using the firmware from Qualcomm I has able to get the board to work (note, it uses WLAN.HSP.2.0):

Comment 1 Kalle Valo 2022-05-16 16:33:32 UTC

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

Comment 2 Dmitry Baryshkov 2022-06-01 12:33:34 UTC

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

One issue per report, please. 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.
