Wireless driver for Broadcom BCM43228

[M4]

Hi guys,

I have a laptop with an Intel HD4400 video card and a Broadcom BCM43228 wireless card.
As per Intel's requirements (https://01.org/linuxgraphics/downloads/2014/2014q1-intel-graphics-stack-release), I upgraded my kernel to 3.13.6, installed the driver and now my video card is working.

My next problem is that I need the wl module for my wireless card. I tried to use the module included in the wl-modules extension (from the repository), but I got a invalid vermagic error (and rightfully so).

I downloaded the Broadcom driver (http://www.broadcom.com/support/802.11/linux_sta.php), but I don't know what extensions I need to make it.

Could you please help me out with a hint?

Best regards,
M4

If you are using a custom kernel, use modules built with your own kernel includin wl, alsa, etc. Modules in repo will not work due to different kernel version.

Hi Juanito,

I tried the instructions as described in the link and everything worked beautifully.
For the second attempt I replaced linux-3.8.13-patched with the kernel I want to use (linux-3.13.6) and I receive the following error(s) when I attempt to make the wl module:

Code: [Select]

This seems to be the function that's causing the error:

Code: [Select]

static int
wl_reg_proc_entry(wl_info_t *wl)
{
char tmp[32];
sprintf(tmp, "%s%d", HYBRID_PROC, wl->pub->unit);
if ((wl->proc_entry = create_proc_entry(tmp, 0644, NULL)) == NULL) {
WL_ERROR(("%s: create_proc_entry %s failed\n", __FUNCTION__, tmp));
ASSERT(0);
return -1;
}
wl->proc_entry->read_proc = wl_proc_read;
wl->proc_entry->write_proc = wl_proc_write;
wl->proc_entry->data = wl;
return 0;
}

Is there anything I can do about this? Note: my knowledge of C and C++ is nearly laughable.

Thanks.

The problem seems to be that linux kernel development proceeds much faster than broadcom's diver release cycle - if you look at:

http://tinycorelinux.net/5.x/x86/tcz/src/wl/compile_wl

you can see that 11 patches were required for their previous driver release.

I'd recommend that you take a look at the latest debian experimental release (or similar) driver and see if they've patched up to 3.13.6
