Discussion and updates regarding Broadcom Wifi related support. Parent thread is #71.

Current Status:

NOTE: Firmware from macOS Catalina is currently known to fail to initialize with brcmfmac. Use firmware from a macOS Mojave or lower installation, otherwise you can find the necessary files in my up-to-date archive here: https://packages.aunali1.com/apple/wifi-fw/18G2022

• [x] Firmware Loading
  • [x] BCM4355 (MacbookAir8,y)
  • [x] BCM4364 (MacbookPro15,x)
  • [ ] BCM4377 (MacbookPro15,4+ [2019])
• [x] Frequency Bands
  • [x] 2.4 GHz
  • [x] 5 GHz
• [x] Security Protocols
  • [x] WPA
  • [x] WPA2

Unfortunately, due to the nature of how tightly linked .clmb files are to each model variant, generic distribution of firmware is currently impractical.

Hi everyone! I've been following this thread as I work on getting a USB SSD with linux that works on both of my Macs: MacBookAir8,2 (2019 MacBook Air) and iMac19,1 (2019 iMac). Fortunately the 2019 iMac does not contain a T2 chip, so things work fairly well out of the box.

I'm attempting to get WiFi working on both models. The iMac seems to have the same chipset as the MacBookPro15,x (BCM4364, codename Midway) but the MacBook Air has a BCM4355 chipset (codename Hawaii). I created and applied this patch (based on the work from @MCMrARM): https://github.com/jhohisel/macbookair8-2-linux/blob/master/brcmfmac.patch and copied the firmware from macOS.

However, the firmware fails to load (iMac):

[   20.314189] usbcore: registered new interface driver brcmfmac
[   20.330616] brcmfmac 0000:03:00.0: enabling device (0000 -> 0002)
[   20.439205] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac4364-pcie for chip BCM4364/3
[   23.374627] brcmfmac 0000:03:00.0: brcmf_pcie_download_fw_nvram: FW failed to initialize

MacBook Air fails with a slightly different error:

[   27.958248] brcmfmac 0000:02:00.0: enabling device (0000 -> 0002)
[   28.121706] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac4355-pcie for chip BCM4355/12

[   31.030139] brcmfmac 0000:02:00.0: brcmf_pcie_download_fw_nvram: FW failed to initialize

I observe a different error when the NVRAM file (.txt) is missing, so I know that it is correctly detecting the presence of these files and attempting to load them.

Top tip: you can discover the firmware filenames that Apple uses by running: ioreg -l | grep RequestedFiles The output will look something like:

"RequestedFiles" = ({"Firmware"="C-4364__s-B2/midway.trx","TxCap"="C-4364__s-B2/midway-X0.txcb","Regulatory"="C-4364__s-B2/midway-X0.clmb","NVRAM"="C-4364__s-B2/P-midway-X0_M-HRPN_V-u__m-7.5.txt"})

@jhohisel well done and nice tip!

I'm experimenting with the WLAN (WiFi) support on my MacBookAir8,1 since a week or so, I've pushed my version of this patch now as well (see reference above). Can you check if your MacBookAir8,2 platform goes along fine with the provided bcm5974, hid, nvme, and brcmfmac patches in https://github.com/ppaulweber/linux-mba? Thx!

I am currently running your bcm5974 and hid patches. Applying them added two-finger scrolling, right-click and function key support.

I'll try the nvme patch now.

NVMe Works! I'll have to try installing it to a partition on the laptop now.

One issue I've been unable to fix is getting the keyboard working when I unlock my root partition during boot. It works during the GRUB menu, then stops working when the kernel prompts to unlock the drive for dm-crypt, then functions immediately after when it loads the bce module.

I built-in mbp2018-bridge-drv to the kernel by adding a Kconfig entry and declaring the source to the Makefile in drivers/. Applied the patches for bcm5974 and hid, then set the module load order in /etc/modules-load.d/bce.conf.

One issue I've been unable to fix is getting the keyboard working when I unlock my root partition during boot. It works during the GRUB menu, then stops working when the kernel prompts to unlock the drive for dm-crypt, then functions immediately after when it loads the bce module.

If you really need the keyboard in this case you have to take a look into your current /etc/mkinitcpio.conf setup. You shall include there the bce in the MODULE=... variable in order that the bce module even gets loaded and integrated into the initramfs creation.

Please focus on wifi in this issue and discuss other topics (like keyboard or NVMe) in separate issues.

Is WiFi (brcmfmac4364) working for anybody (besides @MCMrARM)?

Whenever i'm trying to load brcmfmac module, i'm getting error mentioned below:

[  990.003990] usbcore: registered new interface driver brcmfmac

@mikeeq What kernel patch are you using for WiFi support?

@jhohisel @mikeeq Works perfectly fine for me:

EDIT: I'm using this wifi patch (in my kernel tree) btw.

@aunali1 yep, you're right - I've missed one line when I was generating a patch. https://github.com/mikeeq/mbp-fedora-kernel/commit/d8f5578d4fd9c9ee01c2a125dae30237aefcf391

@ppaulweber could you confirm if that fix is not needed for MacBookAir8,2?

@aunali1 thanks for the hint and I've experimented for my MacBookAir8,1 that this brcm driver uses the same RAM base as the brcm driver of the MacBookPro15,x. It now allocates and loads correctly the firmware, and I get the wlan interface.

@jhohisel can you check if this latest patch works for your MacBookAir8,2 as well, thx!

@mikeeq it does need the same fix, which I've already updated in my repo (see commit reference above)

@ppaulweber The good news is that now the card is correctly recognized and shows as a WIFI device. The bad news is that I can't seem to connect to my network using it. It repeatedly times out and prompts for the password. I tried switching from wpa_supplicant to iwd as suggested in issue 71, but no difference. I also tried using wicd instead of NetworkManager, it fails to connect saying bad password. I have not yet tried an open network, and yes I am entering the correct password.

Has anyone else experienced this?

I am able to connect to my network using a USB WIFI card.

@jhohisel try to reload brcmfmac kernel module. I'm experiencing the same issue and after module reload I'm able to connect to WPA2 network ;)

https://github.com/mikeeq/mbp-fedora#known-issues

@jhohisel I can confirm that for me is wpa_supplicantno longer working as well. With iwdthe WLAN (WiFi) is working as expected. Thx @mikeeq for collecting the known issues in your repo!

I was missing:

[device]
wifi.backend=iwd

From /etc/NetworkManager/NetworkManager.conf

Now I can connect!

Sorry for the silly question all - when I locate the files from mojave, where do I copy them on the linux side?

@macphotoed Just copy the *.trx file to /lib/firmware/brcm/brcmfmac4364-pcie.trx, the *.clmb file to /lib/firmware/brcm/brcmfmac4364-pcie.clm_blob and the *.txt file to /lib/firmware/brcm/brcmfmac4364-pcie.Apple Inc.-MacBookPro15,1.txt

Amazing - thank you again @aunali1 - got the files, tjust grappling with the iwd/wpa_supplicant issue! And bluetooth for some reason?

By the way 5Ghz generally works for me, through a full multiband 5ac does not achieve full speeds.

Sorry. I'd like to ask if I don't have IDA，how can I get the wifi firmware? Do anybody can share one with me. Mine model is mbp2010 13inch.

It seems that with 5.2.11, 5 Ghz works without any problems, and in some cases faster than macOS!

@wzygzlm I mean, this no longer requires IDA, the firmware is in /usr/share/firmware on OS X.

can anyone tell me where the trx and clmb files are? On Arch if it makes any difference.

TL;Dr with the wifi is to first find your firmware files using ioreg -l | grep C-4364, then copy them from /usr/share/firmware/wifi from OS X. On Linux, the .trx file for your model goes to /lib/firmware/brcm/brcmfmac4364-pcie.bin, the .clmb goes to /lib/firmware/brcm/brcmfmac4364-pcie.clm_blob and the .txt to something like /lib/firmware/brcm/brcmfmac4364-pcie.Apple Inc.-MacBookPro15,2.txt All of this requires a kernel patch: https://mrarm.io/u/Paste%202019-07-26%2012-30-16.txt

Anyone else not have this working on MBA 8,1(air 2018) it shows up as a ethernet device, thanks :)

@EmmaDSamms sorry, what? Show the output of lspci?

Hi people, for me I have the files in /lib/firmware/brcm/ exactly as @MCMrARM mentioned but when I run modprobe brcm80211 either in boot time or after, my arch-linux just freeze completely. How can I investigate it? because it just hangs and I need to reboot... If I remove the files, it just starts normally but without wifi working (as expected)

So I've completely uninstalled MacOS and think I copied over the wrong firmware files before wiping it out. Would anyone happen to have firmware files for MacBookPro15,x T2 touchbar model?
Need...

"Firmware"="C-4364__s-B2/kauai.trx"
"imagename"="C-4364__s-B2/kauai-X0.clmb"
"NVRAM"="C-4364__s-B2/P-kauai-X0_M-HRPN_V-u__m-7.5.txt"

I'd suggest against uninstalling MacOS completely because of MacOS being your best firmware update source, so you should keep it if you want to say, update bridgeOS.

Is it possible to apply this procedure to MBP 13,3? Taking the .trx, .clmb and .txt from osx and putting them in linux?

~~I can't get it working on my MBP 2019 15,1. I installed iwd, NetworkManager, enabled the services iwd and NetworkManager, set iwd as default wifi backend in /etc/NetworkManager/NetworkManager.conf, copied the three files from OSX to proper names in /lib/firmware/brcm/. I have aunali1's linux mbp kernel which contains the wifi patches. What am I missing? dmesg says this after boot:~~

Edit: I guess I was missing the bridge/bce module, not 100% sure though

After following @MCMrARM's guide to copy the WIFI firmware files I get the following error when the firmware files are loaded (dmesg | grep brcm output):

I am having the same issue @geovie. This is the dmesg with brcmfmac.debug=2097150. (Some omitted).

From what I understand, the firmware is executed not on the CPU but on the Wifi device. Is there a way to make the Broadcom chip talk back so we can know what's going on? I noticed that there's a fwsignal.c file in the kernel tree that suggests it kinda does that, but I don't know how to use it.

Let me know if any more information is needed.

similar issue with mbp 15,4 it uses a BCM4377 with a device id: 4488 coultn't find anything about it. attempted to implement it like in https://mrarm.io/u/Paste%202019-07-26%2012-30-16.txt but with 4488 instead of 4464 & 4377 instead of 4364, copied the trx, clmb, and txt, from macOS but when i load the brcmfmac module this happens:

on macOS:

$ ioreg -l | grep RequestedFiles
"RequestedFiles" = ({"Firmware"="C-4377__s-B3/formosa.trx","TxCap"="C-4377__s-B3/formosa-X3.txcb","Regulatory"="C-4377__s-B3/formosa-X3.clmb","NVRAM"="C-4377__s-B3/P-formosa-X3_M-SPPR_V-u__m-3.1.txt"})

on linux 5.4.6:

# modprobe brcmfmac
[24.xxxxx] brcmfmac: brcmf_fw_alloc_request: using brcmfmac4377-pcie for chip 4377/4
[26.xxxxx] brcmfmac: 0000:01:00.0 brcmf_pcie_download_nvram: Invalid shared RAM address 0xfffffff

then my mac freezes and after a few seconds it restarts. this only happens when i have the brcmfmac4377-pcie* files in /lib/firmware/brcm otherwise it obviously just exits with cant find the files.

would be nice if anyone could help me :)

@yurnam The patch that you are basing your changes on is incomplete as it does not include the rambase address diff.

Since this a new chip variant, we can potentially determine the rambase by enabling some more debug info. Please post the dmesg output with the additional kernel argument brcmfmac.debug=2097150. I'm particularly interested in the line containing brcmf_chip_get_raminfo.

Can you also clone this repo and runget-info.sh and PR the results. the 15,4 variant seems to differ quite a bit AFAI can tell.

oh sorry, I was using the patch which includes the rambase address 0x160000 i used this address also for the 4377 chip, which was probably a bad idea. if i change or remove it, the mac doesnt freeze anymore.

anyway i made a PR to your repo with the mbp15,4 dumps thank you!

@yurnam Hmm, it seems that the rambase address needs to be found through trial and error. Can you please test through the rambase addresses in this switch case (0x160000 is already known not to work).

dmesg.txt tried all of them output looks always like this:

full dmesg output is in attached file.

is there any other way finding out what to do;

just trying to bruteforce the rambase address doesn't seem to help

I am having trouble getting my Macbook Air 8,2 to get wifi. Here is what I did:

From MacOS: ioreg -l | grep RequestedFiles C-4355__s-C1/hawaii.trx, C-4355__s-C1/hawaii-X0.clmb, C-4355__s-C1/P-hawaii-X0_M-YSBC_V-u__m-4.3.txt

... So I copied these files and I installed fedora.

From Fedora:

I pasted these files as such:

C-4355__s-C1/hawaii.trx -> /lib/firmware/brcm/brcmfmac4355-pcie.bin C-4355__s-C1/hawaii-X0.clmb -> /lib/firmware/brcm/brcmfmac4355-pcie.clm_blob C-4355__s-C1/P-hawaii-X0_M-YSBC_V-u__m-4.3.txt -> "/lib/firmware/brcm/brcmfmac4355-pcie.Apple Inc.-MacBookAir8,2.txt"

I definitely did not make any typos when I plugged this in. The wifi does not come online. Did I miss any steps? Any help would be greatly appreciated

Hey @jhohisel you seemed to have success getting the wifi drivers working on a MacBookAir8,2. Any chance you can see anything I am doing wrong with my configuration?

Quick follow up, wanted to also include @ppaulweber into this conversation as you also seemed to have success at loading brcmfmac4355 successfully. Any chance you can think of what I am doing wrong? Also take a look at this thread: https://github.com/mikeeq/mbp-fedora-kernel/issues/3#issuecomment-572193109

Hey @aunali1 I think it might be time to remove the check mark from MacBookAir8,y... I don't think it is loading properly at this point and the only person who claims to have gotten it to work properly has seemingly disappeared. @jhohisel

@ktb92677 Can you try using my kernel patches to see if that makes a difference? I also have lingering suspicions that certain revised models have entirely different FW (Ex. 15,1 2018 uses kauai whereas 15,1 2019 uses midway). Not exactly sure how to proceed, we might have to add functionality found in Apple's BCMWLAN driver that is not present in brcmfmac.

@aunali1 Is this the patch you are referring to? https://github.com/aunali1/linux-mbp-arch/blob/master/wifi.patch Because if so it is nearly identical to the patch I am already using: https://github.com/mikeeq/mbp-fedora-kernel/blob/v5.4-f31/patches/wifi.patch

@yurnam Others have had success using the firmware archive from macOS Mojave I have hosted here: https://packages.aunali1.com/apple/wifi-fw/18G2022

Cool, thanks, I'll try this now :)

Sadly, no luck with the FW from Mojave. but with rambase 0x160000 i don't get a system freeze anymore, just a FW failed to initalize like before.

same with all the rambase addresses (0x160000, 0x180000, 0x198000, 0x200000)

Update: With Rambase address 0x170000 I get: `# modprobe brcmfmac $ dmesg -w

On my 15,2 wifi spins forever looking for networks unless I boot with wifi off in network-manager, connect to my phone for internet using bluetooth, then enable wifi. Once I've connected once to the phone the list of wifi networks to connect to is populated normally and connecting is no problem.

Hello,

I have the MacBook Pro (Retina, 15-inch, Late 2013) 03:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03)

What are the exact macOS instructions to extract firmware and make it a bin file?

I run ioreg -l | grep RequestedFiles and i get no results but wifi works on macOS

@yurnam I have a MacBookPro15,4 too, and I am trying to get the WiFi to work, did you manage to make it work?

@MoonPadUSer Which kernel/distro are you testing?

@aunali1 I'm running your linux-mbp-arch kernel on Manjaro KDE 20.0

Edit: I ran sudo modprobe brcmfmac debug=xxx (whatever you told yurnam a while ago) and this is what came out after running sudo dmsg | grep -i brcmfmac

@MoonPadUSer Unfortunately not. never got past this in dmesg:

@MoonPadUSer Can you pastebin/gist the full dmesg output?

@aunali1 https://pastebin.com/bqWZAk77

@MoonPadUSer Unfortunately the kernel message ring buffer filled up and cut off the important bits. Please pastebin/gist one after a recent reboot.

@aunali1 https://pastebin.com/js3tefDX This one should have all the brcmf stuff in it

@yurnam Yeah looks like the rambase is correct, but there is functionality missing in brcmfmac that is causing iee80211's etheraddr query request to fail. I'm assuming there's more to this chip's init process than what is done by brcmfmac.

@npx001 Care to elaborate on what you have found "looking inside" the apple driver?

@yurnam @MoonPadUSer Does an interface showup at all?

@aunali1 if I run 'ip link show' it only shows lo and an ethernet one

as dmesg shows brcmf_detach there can't be an interface for the wifi adapter only lo and eth0 show up

@yurnam have you tried the catalina files already?

Just as a side note: I hosted a repository at https://github.com/stefanpartheym/mbp15-wifi-driver which contains the wifi driver files from a MacBookPro15,2 (Mojave), maybe that helps.

@MoonPadUSer yes i tried both catalina and mojave files catalina files caused the OS to freeze when loading brcmfmac

@aunal1 I'm not sure if this is like everything we had before but this log looks better to me as far as I can remember the other ones:

so ... I'm gonna take a look at the brcmfmac driver rn, and look what causes these errors to appear:

the error is always the same, but I don't know what it means, so if anyone know what error -5 is, please tell me

@yurnam don't you think it's kinda weird that ip link show shows an ethernet device, but the MacBook itself, doesn't have a physical ethernet port.

@MoonPadUSer Thats an NCM interface exposed by T2 for all userspace communication between macOS and itself.

@aunali1 oh, ok, thanks :) btw, if you have access to a MacBookPro15,2 (or whatever the model is with the BCM43602) it could be great if you could send the output of sudo dmesg | grep "brcm" and ip link show

@MoonPadUSer BCM43602 is a chipset used on pre-T2 MBPs. Any specific reason you are looking into it?

@aunali1 oh, I thought that would be the one from the other MacBookPro15,x but if it isn't I'd like to see those outputs from a mac with an BCM4364

@MoonPadUSer i know, but the eth0 interface doesn't have to be a Physical Port, it is most likely some internal device that is seen as ethernet device by linux

@yurnam yeah, aunali1 already told me 'bout that :)

@MoonPadUSer I'm on a MacBookPro15,2

@stefanpartheym vielen dank! @yurnam does suspend work for you? because for me I have to restart it after I closed the lid

@MoonPadUSer no suspend doesn't work either.

Just a reminder: Please keep this issue focused on wifi support and discuss other topics in separate issues.

about bcm4377 - looking "inside" apple driver.. is almost identical as bcm4357 if something has to be patched/modded should be around linux driver for 4357 i.e "brcmsmac"

@npx001 there is afaik no BCM4357 only a BCM43570

@MoonPadUSer BCM4357 is AFAIK used in iphones only

@npx001 there is afaik no BCM4357 only a BCM43570

sorry, my mistake, there is 0x4357 but is deviceID not chipID

@npx001 oh, ok so do you know the chipID?

@npx001 oh, ok so do you know the chipID?

if ida decom is correct, bcm 4377 -> chipID is dec: 4377 hex: 0x1119

Currently on a Macbook Pro 15,3. Having some issues with the wifi not accepting firmware. Attempting this on gentoo. Currently got my patched kernel to boot with a couple other issues I'm figuring out. Anyone with the same model able to tell me which firmware they're using? I downloaded the kauai (X3) files from aunali1's repo

"RequestedFiles" = ({"Firmware"="C-4364__s-B2/kauai.trx","TxCap"="C-4364__s-B2/kauai-X3.txcb","Regulatory"="C-4364__s-B2/kauai-X3.clmb","NVRAM"="C-4364__s-B2/P-kauai-X3_M-HRPN_V-m__m-7.7.txt"})

I have MacBookPro15,4 (hw info in this repo) with

If I use modprobe brcmfmac rambase_addr=0x170000 with the Catalina firmware I get nowhere.

The same command with the Mojave firmware, posted previously by @aunali1 gives

like @yurnam and @MoonPadUSer have already shown in https://github.com/Dunedan/mbp-2016-linux/issues/112#issuecomment-573615174 and https://github.com/Dunedan/mbp-2016-linux/issues/112#issuecomment-628034019

Any more ideas how to debug, or maybe somebody who's got newer firwmare which we can try?

Checking in here with a MacBook Pro Late 2015 - 13" Retina (MacBook 12.1)

I have combined a lot of solutions into a Buildroot / Skiff package here:

• https://github.com/paralin/SkiffOS/tree/master/configs/apple/macbook

WiFi on 2.4Ghz networks works fine, with the firmware .txt file, 5.8Ghz networks also work fine.

However on one of my older MacBooks from the same model, the 5.8Ghz doesn't work at all even with this configuration, and 2.4ghz is sometimes glitchy / spotty. It has the same broadcom card. Could be something to do with the newer MacBook being exposed to an updated MacOS recently, which may have updated the firmware to the MacOS version?

@paralin This issue is for MacBookPro models with a 15 and onward model designation corresponding to a 2018 and onward mfg date.

@aunali1 the laptop I'm talking about uses BCM43602 I guess, so I suppose it's a different issue, some others in this thread had the same chipset as me with the ~2015 macbooks.

So yeah you're right that should be moved to a separate issue probably. And/or tracked in the bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=193121

I was able to make it work for Macbook Pro 15,3 (2018). BCM4364 using the files from @aunali1 . Currently works with 2.4GHz and stable (can connect from far and close the AP).

Can you list what firmware files you used?

The Macbook Pro Model is A1990, so correction, its model 15,1 (2018) with the Core i9 and 16BG RAM. The files I used for this:

/apple/wifi-fw/18G2022/C-4364__s-B2/P-kauai_M-HRPN_V-m__m-7.7.txt
/apple/wifi-fw/18G2022/C-4364__s-B2/kauai-X0.trx
/apple/wifi-fw/18G2022/C-4364__s-B2/kauai-X0.clmb

My setup is:

$ uname -a 
Linux joax-ubuntu 5.7.0+ #5 SMP PREEMPT Mon Jun 15 08:59:18 PDT 2020 x86_64 x86_64 x86_64 GNU/Linux

The kernel patches I applied were from here: https://github.com/aunali1/linux-mbp-arch

@yurnam did you find a solution for mac pro 15,4 wifi (BCM4377) on linux os? as im currently in the situation where you were i really hope you share the solution with us

@mushoku-ningen unfortunately not. if i find something i will share it here for sure.

Hi,

I have a iMac19,2 with Ubuntu (and MacOS). Kernel Ubuntu is 5.8.1. Wifi card is BCM4364.

In MacOs, return of ioreg -l | grep RequestedFiles is : | | | | | "RequestedFiles" = ({"Firmware"="C-4364__s-B2/nihau.trx","TxCap"="C-4364__s-B2/nihau-X3.txcb","Regulatory"="C-4364__s-B2/nihauX3.clmb","NVRAM"="C-4364__s-B2/P-nihau-X3_M-HRPN_V-m__m-7.7.txt »})

So : "Firmware"="C-4364__s-B2/nihau.trx" "TxCap"="C-4364__s-B2/nihau-X3.txcb" "Regulatory"="C-4364__s-B2/nihauX3.clmb" "NVRAM"="C-4364__s-B2/P-nihau-X3_M-HRPN_V-m__m-7.7.txt"

I copied .trx, .clmb and .txt files to Linux. But what I need to do with .txcb ?

Now, wifi card is available but No wifi network is detected. I didn't patch anything. Should I patch something ? And how to do this please ? I understand patch but I don't understand what files to aplly patch and where are they !

Thank you !

@jbf1983 I think you need to rename the .trx .clmb and .txt files. I made a repository containing a script which does that for you: https://github.com/stefanpartheym/mbp15-wifi-driver This will work as long as you are using BCM4364.
