Hi All,


Device: Broadcom Corporation BCM43602 802.11ac Wireless LAN SoC [14e4:43ba] (rev 01)


I'm hoping someone could steer me in the right direction. I'm busy configuring the linux kernel (4.1.5) according to instructions here - https://wiki.gentoo.org/wiki/Apple_Macbook_Pro_Retina_%28early_2013%29

Instructions request to disable Broadcom IEEE 802.11n WLAN driver, but with that disabled I don't seem to have any other supported wireless in my kernel.


Should this not be enabled? Maybe I should loads as a module instead.

thanks
Charles

Is your PCI device ID listed on wireless.wiki.kernel.org?
Is this the driver you were told to disable?

The wiki article is about BCM 4331 and it does not say anything about the kernel version not supporting 802.11n.

Hi Charles


Right you are, reading further i've now realised you need to disable if you want 802.11n support, but that also relates to a older kernel so hopefully will work.


thanks for the help :)

For [14e4:43ba]
set CONFIG_BRCMFMAC=m
and CONFIG_BRCMFMAC_PCIE=y

And don't forget the firmware.

Hi all,

I'm not entirely sure what do do here, im still trying to understand how modules are compiled etc...

I've installed the broadcom wireless packagee using emerge sys-kernel/linux-firmware.

My conf.d/modules file
Code:
etc/conf.d/modules
# You can define a list modules for a specific kernel version,
# a released kernel version, a main kernel version or just a list.
# The most specific versioned variable will take precedence.
#modules_2_6_23_gentoo_r5="ieee1394 ohci1394"
#modules_2_6_23="tun ieee1394"
#modules_2_6="tun"
#modules_2="ipv6"
#modules="ohci1394"

# You can give modules a different name when they load - the new name
# will also be used to pick arguments below.
#modules="dummy:dummy1"

# Give the modules some arguments if needed, per version if necessary.
# Again, the most specific versioned variable will take precedence.
#module_ieee1394_args="debug"
#module_ieee1394_args_2_6_23_gentoo_r5="debug2"
#module_ieee1394_args_2_6_23="debug3"
#module_ieee1394_args_2_6="debug4"
#module_ieee1394_args_2="debug5"

# You should consult your kernel documentation and configuration
# for a list of modules and their options.
modules="brcmfmac"


Upon kernel boot it fails to load bcrmfmac & using modprobe -a brcmfmac it cannot din the module to load.
I have done a search and cannot find a brcmfmac.ko file, which I assume is the driver.

I can how ever see the following brcmfmac directories exist.

./usr/src/linux-4.1.15-gentoo-r1/firmware/brcmfmac
./usr/src/linux-4.1.15-gentoo-r1/drivers/net/wireless/brcm80211/brcmfmac

Got it to load the module, by redoing make modules_install whilst logged into Gentoo and not from lived chroot env.

lspci shows that the device is not associated with the mode, so onto that.

Have a look at the recent thread.

Hopefully you compiled the driver as a module. Did you? Will you please post your output of modinfo brcmfmac or what the module's name is.

The CONFIG_BRCMFMAC_<subtype> like PCIe, USB and SDIO needed depends on the (PCI) Device ID listed on https://wireless.wiki.kernel.org/en/users/drivers/brcm80211.

Is this the WIFI card of the raspberry pi 3? If so, use the firmware optainable from the openelec github.

In make menuconfig press / to start searching and type brcmfmac

this will give you a hint what you should enable and where to find the particular option(s).

If you've done everything correctly you'll get the module compiled.

thanks that did the trick, as I using lspci I can see the device is now using brcmfmac.

Above is the output Charles and thanks for the help. Recompiling the kernel with some additional features did the trick and now the device is associated with the module.

I however still cannot see the device using ifconfig, so any ideas welcome.

sit0 and lo are the only interfaces listed via ifconfig -a.

ls /sys/class/net

show sit0 and lo.

Will you please post your output of lspci -nnkv | sed -n '/Network/,/^$/p' | head -n -1

After rebooting check dmesg like dmesg | grep -i '08:00.0\|brcmfmac\' but replace 08:00.0 with the exact device's bus ID from lspci.

ankh2054 ...

from the modinfo I don't see the 43602 firmware listed (which from the above linked post seems to be your chipset). Also, those listed are *.sdio firmware. I suspect you are missing firmware (dmesg should provide some clue ITR), perhaps the brcm80211 page on linux wireless can provide some idea of where you can aquire it.

HTH & best ... khay

Networking support->Wireless image

Device Drivers->Networking device support->Wireless LAN image

qlist linux-firmware|grep 43602

make -jX;make -jX modules_install;make -jX install; update boot && modprobe da module && modinfo brcmfmac|grep 43602

You had to mention from the very beginning what hardware you are using.

I honestly didn't knew what hardware ankh2054 was using. He had to mention from the very beginning what hardware he has, right after my reply saw that you've provided a link to earlier conversation where he said what hardware he has.

ankh2054 ... please check for the presence of /lib/firmware/brcm/brcmfmac43602-pcie.bin ... if it's not there can you provide the output of the following:

Code:
# emerge -pvq linux-firmware
# equery -NC files linux-firmware | grep brcm

Also, this user seems to have the same, or similar, macbook, perhaps something of use there.

That only shows sdio firmware. Looks like you forgot to activate CONFIG_BRCMFMAC_PCIE=y .
Please post your output of grep CONFIG_BRCMFMAC .config when you are in the correct /usr/src/<kernel-version> directory.

f /lib/firmware/brcm/brcmfmac43602-pcie.bin did not exist, so I copied from /usr/src/linux-4.1.15-gentoo-r1/firmware/brcmfmac/brcmfmac43602-pcie.bin.
After rebooting I can now see wlp4s0 as a device using ifconfig -a.

Although I still get the following errors.
