Description Dmitry Baryshkov 2023-08-01 21:24:48 UTC

Several Qualcomm platforms incorporate a variant of ath10k / wcn3990 WiFi device.
In particular:
- sm6115 / qrb4210 (used in Qualcomm Robotics RB2 platform) 
- qcm2290 / qrb2210 (used in Qualcomm Robotics RB1 platform)

Unfortunately these devices reject the wlanmdsp.mbn from linux-firmware (because the platform / signature do not match).

Qualcomm / Thundercomm have provided the wlanmdsp.mbn (WLAN.HL.3.3.7.c2-00723-QCAHLSWMTPLZ-1) file for these platform under the redistributable licence (see LICENSE.qcom in linux-firmware).

With this firmware the device probes and seems to work, but regularly generates the following warning:

ath10k_snoc c800000.wifi: chan info: invalid frequency 0 (idx 41 out of bounds)

Comment 1 Dmitry Baryshkov 2023-08-01 21:31:33 UTC

For the reference, relevant dmesg parts.
