[Q] How to compile atrix wifi drivers?

[ambrice]

I am building an Atrix CM7 image with a kernel based on faux123's github kernel-MB860. That kernel builds and works fine. The wifi drivers however, are not working. I have also cloned faux123's atrix-wifi-dev project and built the dhd module by:

cd open-src/src/dhd/linux
make ANDROID_BUILD_TOP=~/projects/android/system LINUXSRCDIR=~/projects/android/kernel-MB860 BCM_INSTALLDIR=~/projects/android/system/device/motorola/olympus/modules CROSS_COMPILE=$CCOMPILER dhd-cdc-sdstd

I get "Error" from the enable wifi option in network settings. I tried insmod'ing the dhd.ko from the adb shell:

insmod /system/lib/modules/dhd.ko firmware_path=/system/etc/wl/sdio-ag-cdc-full11n-minioctl-roml-pno-wme-aoe-pktfilter-keepalive.bin nvram_path=/system/etc/wl/nvram.txt

insmod: init_module '/system/lib/modules/dhd.ko' failed (Invalid argument)

dmesg shows:

Am I building this correctly? Has anyone successfully rebuilt the kernel and dhd driver?

Did you ever figure this out?

Did you (or anyone) figure out how to build the wifi module for CM7? Where do you get the source?

I have successfully built both the kernel and the filesystem, but have not been able to get the wifi module built.

Okay, so apparently this is some sort of secret because I had no luck finding the proper way to build the driver module.
Well, I finally got tired of trying the same thing ('make dhd-cdc-sdstd') over and over only to get nowhere. I went into the makefile and looked around at what kind of options it had for building the module. Turns out there are about 2 dozen different options.
The default option is 'dhd-cdc-sdmmc-oob-gpl' and what it will build if you just type 'make' in the proper folder. Finding that it was probably just as likely as any other option, I did that.
It WORKED!
So the proper command is 'make dhd-cdc-sdmmc-oob-gpl' or just 'make'.
I hope no one minds me digging up an older thread, but I thought I might share if anyone else wanted to try cooking their own kernel. I flailed around with this issue for two days trying desperately to find the answer before I finally figured it out.
