IMX8MP Android 11 WiFi AW-CM276NF

VeeraH — Mon, 18 Jul 2022 06:42:49 GMT

Hi,

We are trying to bring up the AW-CM276NF (88W8997) WiFi / BT combo module. We got the driver up and we could able to scan the wifi networks using command line:

iw dev mlan0 scan => getting the access points around us

iw dev mlan0 connect <access point name> => we could able to connect with the access point.

But when we are trying to use the Android UI, we found the following,

1. WiFi does not get powered on => keeps getting into power off stat

2. WiFi scan is not working, no AP list is populated

3. Could not able to connect with the any AP as well.

Please share your inputs on this.

Hello @VeeraH ,

I.MX8MP-EVK board supports 88W8997 with PCIe interface, WiFi is connected to M.2 interface on board.

Correspondingly, our default android 11 bsp also supports 88W8997 pcie module.

So suggest you check if there are something wrong with your porting procedure.

Regards,

We ported the 88W8997 with SDIO interface for WLAN and got the mlan0 interface on ifconfig.

using iw command, we could able to scan and connect using mlan0 interface.

we got mlan0 and p2p0 interface got created.

while debugging the logcat, we are getting following on WiFI ON using UI.

wifi related configuration settings are fine as below,

wifi.direct.interface => p2p0

Hi @VeeraH ,

I checked android 11.0.0_2.6.0 bsp source, driver is in the path:

~/android_11.0.0_2.6.0/vendor/nxp-opensource/nxp-mwifiex/mxm_wifiex/wlan_src

you can open it Makefile:

......

CONFIG_SD8997=y
CONFIG_USB8997=n

......

8997 with SDIO interface has been supported by the driver. It means that you don't neet to do any porting work.

it means that default android bsp should support it.

it only needs wifi module is on your board.

According to your logs, wifi driver (mlan.ko & moal.ko) is not ready.

Regards,

weidong

Hi,

I also tried with following. With only CONFIG_SD8997 is y, still same behavior is happening.

CONFIG_SD8997=y
CONFIG_USB8997=n
CONFIG_PCIE8997=n

Thanks,

Hello @VeeraH ,

According to you logs, it seems that there are no wifi interfaces,such as wlan0 & wlan1.

wlan0 is STA , and WLAN1 is for hotspot.

Can you check if wifi driver has been build successfully in out directory?

Hi,

NXP SDIO WiFi Driver creates mlan0 interface

but android framework expect and uses the wlan0 as STA.

After changing the information in the following files,

hardware/nxp/wlan/wifi_hal/wifi_hal.cpp
frameworks/opt/net/wifi/libwifi_system_iface/interface_tool.cpp
frameworks/opt/net/wifi/tests/wifitests/src/com/android/server/wifi/SupplicantStaIfaceHalTest.java

we could able to get the WiFi station is up and running on android UI as well.

Please share your inputs.

Hello @VeeraH ,

Yes , right. Android uses wlan0 / wlan1...

for nxp wifi driver, when you load it , you can set interface's name .

like: sta_name=wlan0, uap_name=wlan1 wfd_name=p2p ...
