[88W8997] RF test mode driver/firmware

Hi everyone,

I need to set the wireless module into continuous transmission mode for some RF tests, and I'm struggling on how to achieve that..

System infos : 

Carrier board : Toradex colibri IM.X6ULL

Wifi module : NXP 88W8997 (on Azurwave cm276nf module) using SDIO communication

Kernel version : 5.15.36

Wifi driver : marwell mwifiex

 

  1. From what I've found so far, there is an RF test mode that should be available on the wifi module, which would be activated with the following command.

     

    echo "rf_test_mode=1" >> /proc/mwlan/adapter0/config

    My guess is that once I'll have access to this mode, I'll be able to configure the module to perform a continuous transmission.

    With my current setup, the wifi interface correctly enumerates and I can use it, but there is no such thing as /proc/mlan/.. I also saw that there was an NXP driver (moal.ko / mlan.ko).

    Which driver/firmware should I use ?

  2. I saw (from UM11490) that there is a test software (labtool) that should be used to perform rf tests, but I'd rather avoid using it. Is it mandatory ?

 

Any help/tips would be greatly appreciated

Hello @thibault_lefebvre 

 

1. You could use FP92 driver and document mentioned fw. https://www.nxp.com/webapp/Download?colCode=UM11675

2. If you just want some basic RF test, it is not necessary to use labtool

 

Best Regards
