IW612 integration with iMX8MP

[bgaurav1718]

Hello all.

I am trying to integrate U-Blox's Maya W2 series, which are based on NXP's IW612 chipset, with iMX8MP. Previously, I was working with kernel version 6.6.x in the processor and it had the reuqired drivers pre-installed in /lib/firmware/nxp directory. I could easily follow the "Feature Configuration Guide" document and get my wireless connection set up.

However, I now downgraded to kernel version 5.10.72. I cannot find the drivers pre-installed. I tried to find the recipe for Yocto build system.  But the recipe is not available for Yocto version HARDKNOTT. 

Also, I tried to follow the driver building and installing method mentioned in the github page . I successfully build the driver and copied the contents to /lib/firmware/nxp directory. But when I run the driver installation command, 

insmod moal.ko mod_para=nxp/wifi_mod_para.conf

I get a short message 

I expected longer message as mentioned in the Feature Configuration Guide. 

I am not sure if I followed the instructions correctly. 

I am hoping to find a proper guide to accomplish the task. 

Thank you!!

Hi,

Please share with me the whole terminal output of your test.

Did you copy the fw in /lib/firmware/nxp?

Regards,

Daniel.

Hi,

I have following files in /lib/firmware/nxp directory:

After running the command insmod ./moal.ko mod_para=./wifi_mod_para.conf, I get the short message mentioned in the question.

Please share with me your wifi_mod_para.conf.
I will try to replicate this on my side.

I received new OS with kernel version 6.6. The issue no longer exists when testing with iMX8MP-evk-board. Driver loading process was successful and the interfaces could now be seen in the interfaces list.

For your reference, I have attached the file I was using with kernel version 5.10.x
