Dear all,

 

we want to use a QCA9277-3 WiFi but need a Linux 4.14 driver. As fas as I know the qcacld-2.0 only supports 4.9 kernel and the ath10k driver does not support SDIO at all. Is there any chance to get QCA9377-3 working with kernel 4.14 and even newer ones?

Hi Wolfram,

Can you download the code from here: https://source.codeaurora.org/external/wlan/qcacld-2.0/log/?h=CNSS.LEA.NRT_3.1
This branch has 4.14 support.

You can use this command for checking-out: 

#make a dir
#cd dir
#git init
#git clone git://source.codeaurora.org/external/wlan/qcacld-2.0.git -b CNSS.LEA.NRT_3.1

Thanks.

Dear all,

I want  to use monitoring mode for QCA9377-3 on kernel 4.14. However, I am having multiple build errors (log at the bottom).

I have the following configuration:

 

I have successfully compiled a functioning driver using an older branch from our vendor's repository (https://github.com/8devices/qcacld-2.0/tree/caf-wlan/LNX.LEH.4.2.2.2), but it does not support monitoring mode.

Do you have any more instructions or guides on how to build?

Thanks


Log output:
make -j 4 all

Hi Silvia,

Please check https://www.qualcomm.com/products/qca9377.

The SDK available here has Monitor mode support. Check th ePorting Guide Section "8.5 Install the WLAN host driver alternate modes" for details.

Thanks.
