[imx8m] wifi mesh support

[Andy_Lee]

I would like to ask wifi mesh support at imx8m evk platform w/ SD8987.

I set it like the following in the menuconfig.
CONFIG_MAC80211_MESH=y

CONFIG_MAC80211_SUPPORT=y
CONFIG_MAC80211_SUPPORT_UAP=y
CONFIG_MAC80211_SUPPORT_MESH=y

But, I did not find any mesh point at target evk board.

Could you explain how to enable wifi mesh point at imx8m evk platform ?

Hello, 

While the device support several features, some of them might not be enabled in the BSP .

By any chance, which driver are you using for the device ? You can check in this link the different features enabled in the Linux Board Support Packages (BSPs).

Also, if you are not using those drivers, could you please help me validate that in the document of the features of teh driver to validate if the WIFI mesh is mentioned there ?

Regards

[Andy_Lee]

Hello.

I am using driver like as below

---------------------------------------------------------------------------

SD-UART 8987
BSP version : Linux 5.15.32-2.0.0
Wi-Fi and Bluetooth/Bluetooth LE Firmware version : 16.92.21.p41.3
Driver version : MM5X16322.p3-GPL

wlan: version = SD8987----16.92.21.p41.3-MM5X16322.p3-(FP92)

--------------------------------------------------------------------------

BSP support wifi mesh ? or not ? 

if it is not support wifi mesh point at SD8987,  Is it support wifi mesh support at SD/PCIE9098 ?

Hello, NXP TechSupport team.

Thank you for your kind help.

We are understanding your situation. Also Accepted your current answer.

May I ask you one more time, 

Do you have any update plan of supporting of WiFi Mesh in near future ? 

If you have no plan, You can close this topic.
