Enable mc_policy using mlanutl or during driver load

[nandan-khant]

Hello NXP Team,

I am working on a custom device running android 11 OS and having W8897 wireless chipset. The driver version string is attached in the screenshot.

Driver load commands are as follows:

insmod vendor/lib/modules/mlan.ko
insmod vendor/lib/modules/sd8897.ko host_mlme=1 cfg80211_wext=0xf sta_name=wlan wfd_name=p2p max_vir_bss=1 drv_mode=7 p2p_enh=1 wakelock_timeout=30 shutdown_hs=1

I am using mc_policy mlanutl commands as follows:

To enable mc_pliocy: $ mlanutl wlan0 mc_policy 1

To disable mc_pliocy: $ mlanutl wlan0 mc_policy 0

To read mc_pliocy: $ mlanutl wlan0 mc_policy

I am always getting the following error logs:

255|console:/ # mlanutl wlan0 mc_policy 1
mlanutl: Bad address
mlanutl: mc_policy fail

Please help to enable the multi-channel policy.

Is there any way to enable it by default during driver load? By default it is disabled.

Dear @nandan-khant 

As far as I know there is no driver parameter to enable multichannel policy

On my past experience, mlanutl reported such error (mlanutl: Bad address) if the firmware had crashed.

Could you please check if the firmware has effectively crashed ?

Olivier

Hello @ocourson,

This issue is resolved now.

Thank you for your support.

However, we are facing a different issue now with using wpa_supplicant in Android.

Our DUT is STA and it is not able to connect with AP using the command line. We can connect with AP successfully when we use GUI.

My command: wpa_supplicant -i wlan0 -D nl80211 -c /data/vendor/wifi/wpa/wpa.conf -B

wpa_supplicant.conf file:

ctrl_interface=/data/vendor/wifi/wpa/sockets
network={
ssid="test_5GHz"
key_mgmt=NONE
}

The DUT is not able to connect with test_5GHz  AP.

When I perform scanning explicitly using the following command, it is able to connect successfully.

$ wpa_cli -i wlan0 scan

Attaching console and logcat logs for your reference.

Please help to resolve this issue on Android.

Thanks and Regards,

Nandan Khant
