How to compile the wifi driver ?

[Guest # rm -rf /*]

I compiled the kernel with the source code downloaded here (Thanks to Tom's work!) :

https://github.com/T...ernel_zte_blade

Everything seems to work well except the WiFi , I found that /system/wifi/ar6000.ko could not be loaded .

Is there a solution ? Thanks !

Solved: just modify ar6000.ko with an hex editor like ghex , replace the original version with compiled version(remove "+") , and add "00" after the whole string , the wifi driver now worked well with my kernel

For a start, make sure your kernel is exactly "2.6.35.7-perf+"

If it does not match within the quotes, the wifi driver will refuse to load, as its hard-coded to use that identical/exact version in quotes. Don't ask me why - but I suspect it was pulled from somewhere else and built for that version or that the sources was compiled by TomG for that version.

The wifi driver need to be recompiled .But , till now I could not find available ar6000 driver source code .

I always get compilation errors .

I also wonder why I got "2.6.35.7-perf" , not "2.6.35.7-perf+".

There is no known proper source to date that actually compiles and works, a lot of the sources out there are broken and do not build properly. Look for the script in the kernel source setlocalversion that tacks on the + to the end of it.

It's seems amazing:

I followed instructions here:

http://armin762.wordpress.com/2010/05/24/nvidia-tegra2-getting-wifiatheros-6002-working/

I executed this:

sed -i -e 's:/system/lib/hw/wlan/:/system/wifi/:g' os/linux/ar6000_drv.c

and copied autoconf.h from my kernel source code directory.

Compilation was successful .But, ar6000.ko didn't work.

There's no proper source, and how to fix the wifi ? Does it mean that I can't compile and use my own kernel?

I found this in dmesg

<4>[01-18 14:14:50.459975] [690: busybox]ar6000: please compile with -fno-common

so I modified the makefile and added -fno-common to the end of CFLAGS

but the compiled driver still refuse to load , I still find "ar6000: please compile with -fno-common" in dmesg .

What does it meaning ? The source from tegra didn't work at all ?

[Guest # rm -rf /*]

I found modifying Makefile didn't affect anything

so I replaced the arm-none-eabi-gcc with a script (original file renamed to arm-none-eabi-gcct):

#!/bin/sh

/home/chen/arm-2011.03/bin/arm-none-eabi-gcct -fno-common $@

Now the ar6000.ko could be loaded, but still not work

something in my dmesg:

I tried cat the file and got this error:
