HOWTO: Use b43 driver with 14e4:4315 (Broadcom bcm4312 rev 01)

[k3Rn]

@emas80: i couldn't find any modules.symversion file in my system.

for now i give up on this topic, i don't have enough time at the moment.

i'll keep track on this thread here and will try it again with a fresh ubuntu install when i find the time.

anyway thank you guys for the help so far - i'll be back sometime

greetz,

k3rn

Hi chenxiaolong... I've run your commands, and got the same errors as K3rn... As I can see in his last message, he has no time to help you, but I really would like to get B43 in 2.6.32 so if you have any idea I could test

After rebooting in new kernel, applying the patch and trying to insert the new kernel module I get:

FATAL: Error inserting b43 (/lib/modules/2.6.32-02063203-generic/updates/drivers/net/wireless/b43/b43.ko): Invalid module format

In dmesg I get:

b43: no symbol version for module_layout

I have tried stripping symbols in kernel, but then I get another error stating there're no symbols :S

Any help will be great

Thanks
gFa

K3rn: could you try running these commands:

cd /usr/src/linux-source-2.6.32       #Change to source directory
sudo make oldconfig                   #Use the default (I think) settings for make
sudo make prepare                     #Prepares make to compile kernel
sudo make modules_prepare             #Prepares make to compile kernel modules
sudo make modules SUBDIRS=drivers/net/wireless/b43 #Compiles b43
sudo rmmod b43 ssb wl                 #Unload in-use modules
cd /lib/modules/`uname -r`/kernel/drivers/net/wireless/b43 #Change to b43 directory of current kernel
sudo mv b43.ko b43.ko.backup          #Backup current b43 module
sudo cp /usr/src/linux-source-2.6.32/drivers/net/wireless/b43/b43.ko ./ #Copies new b43 driver to the kernel modules directory (where the drivers are)
sudo modprobe ssb                    # 0R REBOOT
sudo modprobe b43 pio=1              # OR REBOOT

Hope that helps

I have successfully compiled b43 module, just needed one more command:

cd /usr/src/linux-source-2.6.32       #Change to source directory
sudo cp /usr/src/linux-headers-`uname -r`/Module.symvers ./  #Copy symbols dependencies
sudo make oldconfig                   #Use the default (I think) settings for make
sudo make prepare                     #Prepares make to compile kernel
sudo make modules_prepare             #Prepares make to compile kernel modules
sudo make modules SUBDIRS=drivers/net/wireless/b43 #Compiles b43
sudo rmmod b43 ssb wl                 #Unload in-use modules
cd /lib/modules/`uname -r`/kernel/drivers/net/wireless/b43 #Change to b43 directory of current kernel
sudo mv b43.ko b43.ko.backup          #Backup current b43 module
sudo cp /usr/src/linux-source-2.6.32/drivers/net/wireless/b43/b43.ko ./ #Copies new b43 driver to the kernel modules directory (where the drivers are)
sudo depmod -a                       # Refresh modules
sudo modprobe ssb                    # 0R REBOOT
sudo modprobe b43 pio=1              # OR REBOOT

Now, I can insert the module... but my system freezes after few seconds (about 10 secs), any clue?

Thanks

I was getting the same errors and did the same thing (the header version) and got the same system freeze. It got so bad I have done a fresh installation (off a nikon camera no less (I'm overseas)) so hopefully it will work now!

Thanks for the information about the symbols dependencies. I've added that to the script and I reattached the script on my first post.

Sorry for the long wait. I've been studying for my midterms (I'm only a High School freshman. I have to take midterms ). Anyway, I'll try and figure out why it freezes after ten seconds. If you want to remove the driver, you can always boot into an older kernel and delete /lib/modules/YOUR_KERNEL/updates/drivers/net/wireless/b43/b43.ko.

Thank you... If you need some kind of log or something like that, I could try again... i'm still using karmic default kernel (2.6.31) as primary but I can reboot to test whenever you need...

By the way, I downloaded the latests packages from Kernel PPA, version:

2.6.32-02063203

I think they're different than the one that downloads your script, does this affect?

Actually, it does. The script is written for kernel 2.6.32.2, but you have kernel 2.6.32.3. I'll upload a new script in addition to the one for 2.6.32.2. I didn't know that kernel 2.6.32.3 is out already .

Maybe this is the freezes cause

I think I'll wait until you submit the new patch instead of downloading the old kernel packages...

Thanks

[chenxiaolong]

I just uploaded it.

I just uploaded it.

I don't see any diff between the old and the newest patch file :S
