i.MX8X QCA6174 driver and firmware

Question asked by MMar Velasco on Jun 2, 2020

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
