i.MX8X QCA6174 driver and firmware

[mvelasco]

Dear community,

I am using a QCA6174A-5 chipset installed on PCIe interface of an i.MX8X module. I am using Yocto (sumo release) to build tha image. I would like to know if "firmware-qca6174" and "kernel-module-qca6174" recipes install ath10k firmware/driver. If not, I wonder if there is a way to install ath10k.

On the other hand, with  "firmware-qca6174" and "kernel-module-qca6174" I can see p2p0 and wlan0 interfaces, so these recipes work fine. However, I can not set txpower. For example, setting txpower to 900mBm = 9dBm :

iw dev wlan0 set txpower limit 900 

gives me nothing changes in wlan0's txpower parameter. It remains unchanged to 0dBm.

Interface wlan0
   ifindex 6
   wdev 0x1
   addr 00:0e:8e:92:98:8f
   type managed
   txpower 0.00 dBm

Is it a driver/firmware issue?

Thanks very much in advance,

MM

Hello,

Yes, as specified in the i.MX Reference Manual ATH10K driver requires certain nodes to be defined in the device tree, section 4.13.6 Device Tree Binding

This may be a driver issue, could you try with a more recent kernel version which also integrates more recent driver/firmware?

Hope this helps,

Best regards,

Aldo.
