88W9098 on TI AM62x

[dpog]

I'm trying to compile the nxp-imx/mwifiex repo for use with an ARM64 AM62x-Board and followed this instructions: https://community.nxp.com/t5/Wireless-Connectivity/Wifi-Driver-Build-for-Generic-ARM64/td-p/1598321

The driver compiles without problems and I placed the moal.ko & mlan.ko in the /lib/modules/[...]/extra folder as well as the .conf and .bin in the firmware/nxp folder.

When I try to load the module, I get following errors:

Any hints how I can solve this? For compilation I use the Yocto SDK, the KERNELDIR in tmp/work/[...]/build (kernel buildfiles, analog to the build files in the NXP-BSP) and the nearest branch in mwifiex (lf-6.1.55_2.2.0 for use with linux-ti-staging 6.1.46)

Hi, @dpog 

Thanks for creating case to us.

From your logs, I think you need also to compile cfg802.11.ko based on your host platform.

You can search how to cross compile cfg80211.ko on Linux to fix this error.

Usually, you can configure it through make menuconfig during compiling Linux kernel BSP.

Also, if after you compiled cfg80211.ko, you still meet any failure, please provide me your full dmesg logs for further debugging.

And for your information, we will start our Mid-Autumn public holiday from tomorrow and come back to office until 18th/Sep.

So please allow me replying delay for this case.

Sorry for the inconvenience to you.

Best regards,

Christine.​

Hi， @dpog 

Does the 88W9098 work on your side?

I am back from the public holiday, please do not hesitate to let me know if still need support.

And also provide me your detailed current status and related dmesg logs.

Best regards,

Christine.

Hi @Christine_Li,

I was occupied by other tasks, so i didn't notice the holiday

The 88W9098 still doesn't work, but thats probably because of a misconfiguration on the SDIO part.

The driver is being loaded successfully with cfg80211.ko present, for some reason it was not installed in the image. I will keep you posted if I succeed or face other dificulties!

Best regards,
Dominik

Hi, @dpog 

Thanks for your feedback.

If you need more time, would you mind help to close this current case, and after you verified, then create a new case to us?

It would be appreciated if you could create a new case after you verified still have issue or have other new questions.

Best regards,

Christine.

Of course, I will close this one.

Best regards,
Dominik
