I have INTEL Wireless-AC 9260 2230 2x2 AC+BT Gigabit vPro connected to the M2 interface on SK-TDA4VM board. Where can i get the drivers for this.

    Hi Deepankar,

    The drivers for the WiFi card are packaged with Edge AI SDK: https://www.ti.com/tool/download/PROCESSOR-SDK-LINUX-SK-TDA4VM

    On the prebuilt image, they will be under /lib/firmware. The driver can also be downloaded from Intel's website. Please reach out to Intel for information specific to the driver.

    Regards,

    Ok then I am assuming the drivers will load automatically. But what commands do i use to connect it to a Access point?

    I tried wpa_cli which gives a cli to connect but it is not supported. Then i checked with iw dev command. And the  wifi module seems to be in AP mode. Any suggestions on how  to supply the wifi passphrase and name? I tried to manually add a entry in wpa_supplicant.conf but that also did not help.

    Hi Deepankar,

    Here is the documentation for enabling the WiFi card through Edge AI SDK on the SK-TDA4VM: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-sk-tda4vm/08_02_00/exports/docs/wifi_oob_demo.html 

    Let me know if this helps.

    Regards,

    Thanks for the link. Meanwhile i also found another method that works. May be it will benefit someone

    Step 1: When you boot the board . The wifi module is in AP mode. 

    Step2: Connect over UART and first disable the interface

    • sudo ip link set wlp1s0 down

    step3: Now you can change the mode of wifi Module  from AP to "Managed" using  the following command.

    • sudo iw wlp1s0 set type managed

    step4: Bring the interface up

    • sudo ip link set wlp1s0 up

    step5: optional step: Check if the wifi module is scanning

    • iw dev wlp1s0 scan | grep SSID

    You should  see a list of available wifi devices

    Step6: Now we pass our wifi SSID and credentials to wpa_supplicant.conf

    • wpa_passphrase <name_of_my_ssid>  <my_password> | sudo tee /etc/wpa_supplicant.conf

    step7:  Enfore connection. Please note  that if you dont use & then you will not be able use the terminal. & makes the command run in background. But the outputs will still be shown on your console. You can also reroute the outputs to another null interface. Search for that yourself.

    • sudo wpa_supplicant -c /etc/wpa_supplicant.conf -i wlp1s0 &

    step8: check if connection was successful

    • iw wlp1s0 link

    You should now be connected to the internet. Add the commands in step 2,3,4,7 in .bashrc to automate it over every boot.

    CAUTION. The name of your interface can be something else. Then use that and not wlp1s0
