Dear NXp,

As i am not able to bringing up the wifi module that is connected on imx8 Nano evk board, running below commands to bring up the interface, included wifi-tools to my .bblayer.

is there any other packages need to be add .bblayer to bring up this ?

CMD outputs...

root@cu:~# ifconfig wlan0

ifconfig: wlan0: error fetching interface information: Device not found

root@cu:~# ifconfig wlan0 up

ifconfig: SIOCGIFFLAGS: No such device

root@cu:~# ip link set wlan0 up

Can not find device wlan0

Hi shilesh_babu,

You can check this post on the Murata forum: https://community.murata.com/s/question/0D55F000096S0K5SAK/imx-8m-nano-evk-wifi, which talks about a similar issue.

You can also refer to this Blog on the Murata forum: https://community.murata.com/s/article/Drill-down-Steps-to-Bring-up-1MW-on-i-MX8M-Mini-EVK. This describes the process of bring up the on-board Wi-Fi module on i.MX 8MMini. The procedure would be similar for 8MNano.

Best regards

Hi everyone,

I'm having same issues in 2023 with the 8MNANOD4-EVK and the v6.1.1 Linux Distro version. I go through module activation with:

modprobe moal mod_para=nxp/wifi_mod_para.conf

After this, dmesg show:

Seems driver exists but its not as verbose as i would like. Unfortunately, interface its not appearing

I tried to set the wifi network credentials in wpa_supplicant.conf and then updated with the command

wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf -D nl80211

But seems not to brings up the interface

I tried this process with full and multimedia image in the application images provided. I also try v5-15.71 and v5.10.52, same results as above.

Someone have any idea what could be happening? Thanks!

How is this wifi controlled ? In general

1 - check the interface, generally sdio, by dmesg, check the driver is up and device is detected.

2 - check finally ethernet driver fro wifi is running/loaded (lsmod)

3 - check for firmware load error messages, as dmesg | grep err or "dmesg | grep firm" and messahes around that
