RPi4: WiFi client crashes often (brcmf_fw_crashed: Firmware has halted or crashed) #3849

Open jgilles opened 3 years ago

jgilles commented 3 years ago

Describe the bug WiFi client stops working and does not recover (Cypress firmware crashes). This happens to my RPi4 almost every day and I must reboot to recover it. After reboot, it always works but will fail again sometime later that day (duration seems random). Raspbian is up to date with all upgrades as of 9/11/2020.

To reproduce Use WiFi client mode on RPi4.

Expected behaviour WiFi keeps working reliably.

Actual behaviour WiFi client stops functioning entirely.

Additional context I am reproducing this daily with a TP-Link Archer A7 router (5GHz)

JamesH65 commented 3 years ago

Is it possible to test at 2,4G to see if that works OK? What sort of signal strength are you seeing - is it right on the edge? Does moving the Pi closer make the problem more or less common?

jgilles commented 3 years ago

Looks like it is already using 2.4GHz (I thought it was using 5GHz since the LXDE WiFi panel control shows 5G and the router supports it). Signal strength is strong.

Here is the info from wpa_cli:

Is there any other debugging I can do to help?

WIFI Router: TP-Link Archer C7

jspuij commented 3 years ago

It's a bug with the IEEE 802.11r fast roaming implementation in the Wifi driver. Disabling fast roaming on my mesh router fixed this issue.

Indeed I have a mesh setup with several routers, but ieee80211r (Fast BSS transition) is not active. How did you come up with that? Do you have any tips how to find out the reason for the crashes in my setup?

jgilles commented 3 years ago

I only have a single router, no mesh. I have also tried using separate SSIDs for 2.4GHz and 5GHz, so that the Pi would not switch between them and it didn't help.

Got the answer here: https://github.com/raspberrypi/linux/issues/1342#issuecomment-681948365 I've not had any wifi crashes anymore since disabling fast roaming on my TP-Link deco mesh. However I've also added an automatic reboot in my crontab whenever the gateway is unreachable, just in case.

jgilles commented 3 years ago

I can't find any setting on my TP-Link Archer A7 to disable fast roaming, unfortunately. There is only a section for "OneMesh" configuration and it doesn't let you change anything, especially if you don't have other devices...so I don't have a way to test this.

freeforall2 commented 3 years ago

Having the same issue here. Wifi is crashing on new RPi4 and the only way to recover is a reboot. As a Wi-fi AP, I am using Netgear Orbi.

@freeforall2 Rebooting is also my only current workaround 🙁

pelwell commented 3 years ago

What does dmesg | grep Firmware: show, @freeforall2?

Anyone experiencing a crash like this, please download the new clm_blob file: https://drive.google.com/file/d/1J8DdbsrZcSkDYKUPsdy2RvncttSwQdBH/view?usp=sharing

Install it with:

pi@raspberrypi:~$ sudo mv /lib/firmware/brcm/brcmfmac43455-sdio.clm_blob{,.bak}
pi@raspberrypi:~$ sudo cp brcmfmac43456-sdio.clm_blob /lib/firmware/brcm/brcmfmac43455-sdio.clm_blob

[ yes - there is a rename from 43456 to 43455 in that copy ]

pelwell commented 3 years ago

Thanks - that is the most recent firmware we have. It's interesting that the location of the firmware crash is the same as in the OP. I'll flag it up to Cypress.

freeforall2 commented 3 years ago

@pelwell Thanks ! Do you still suggest that I install the clm_blob you sent for testing ?

pelwell commented 3 years ago

Yes please - it might at least avoid the problem for you.

pelwell commented 3 years ago

Cypress have provided another firmware to test. I suspect it's just a current build rather than one expected to solve the problem, but it's worth trying: https://drive.google.com/file/d/13u_Ipf6yUATl38HyVNiHG3H2BVxCzfkB/view?usp=sharing You'll need to rename it when instalingl it (and reboot afterwards):

pi@raspberrypi:~$ sudo mv /lib/firmware/brcm/brcmfmac43455-sdio.bin{,.bak}
pi@raspberrypi:~$ sudo cp cyfmac43455-sdio.bin /lib/firmware/brcm/brcmfmac43455-sdio.bin
freeforall2 commented 3 years ago

@pelwell I installed the clm_blob you provided. I am going to monitor for 24 or 48 hours. If it doesn't fix the issue, I will install the new firmware. Let me know if it doesn't make sense and I should go with a different approach. Thanks !

pelwell commented 3 years ago

No, that sounds good - it's usually best to change one thing at a time.

pelwell commented 3 years ago

There's now a dedicated test image Cypress would like you to run: https://drive.google.com/file/d/1ggSFL4YvPRkm0e-uYdrYWGG1TBEprtat/view?usp=sharing Again, it will have to be renamed bcrmfmac43455-sdio.bin when installing it.

Please try it, and upload the logs for any failures you see.

freeforall2 commented 3 years ago

@pelwell, thanks. So here is my feedback : I only installed the clm_blob you provided and it looks like it fixed the issue (no crash since 48h while before I had at least 1 crash per day). Question : What do you recommend as a next step ? Should I revert to the old clm_blob and install the last bcrmfmac43455-sdio.bin you provided ? or should I keep the clm_blob and it can be considered as the fix ?

pelwell commented 3 years ago

The firmware shouldn't crash, no matter what, so if you are willing it would be nice to install the trial firmware, revert the blob and let it crash once (or perhaps it won't), grabbing the kernel log. After that you can apt update and sudo apt install firmware-brcm80211 to restore the new blob (we released it yesterday).

freeforall2 commented 3 years ago

@pelwell before installing the trial firmware I decided to continue monitoring for an extra couple days. It actually just crashed ( with the clm_blob you provided still in place). You can find below the log (please tell me if you need more logs). What would you recommend at this stage ? should I revert the clm_blob to the original and install the trial firmware ? Thanks for your help !

Run the new firmware with brcmfmac.debug=0x100000 in cmdline.txt, and when it crashes upload the output from dmesg.

Thanks - I've forwarded the log to Cypress.

pelwell commented 3 years ago

In a remarkably quick turnaround there's a test firmware with a possible fix: https://drive.google.com/file/d/1YOvhSmyCmQkoF9vcsRDD5oxFkj0VGuM7/view?usp=sharing (It will have to be renamed and installed as before).

freeforall2 commented 3 years ago

@pelwell thanks ! it was very quick ! I installed the test firmware. I will monitor for a few days and let you know the results. Just one thing : at some point, I reverted to the old clm_blob. Do you confirm that I shouldn't touch it for now. Or should I update it ? Thanks

pelwell commented 3 years ago

I don't think it will make a difference, but since the new blob is part of the current firmware package I would prefer you to use it.

Sprout-man commented 3 years ago

@pelwell Created an account to say thanks for posting the test firmware, and note that it's been solid for me the last several days. Prior to installation, I was the in the same boat, with a regular daily loss of wifi connectivity, but so far no issues post-update (~4 days at this point).

freeforall2 commented 3 years ago

@pelwell same here, no crash since 7 days. I can confirm that it fixed the issue. Thanks !!

pelwell commented 3 years ago

Thanks - I'll wait a while for the clm_blob change to hit a wider audience, then release this.

robertaramar commented 3 years ago

Is the clm_blob now released? I did an update and after that downloaded your clm_blob from Google drive and found their md5sums be identical.

pelwell commented 3 years ago

Yes - the new clm_blobs where published at the start of the month (it was mentioned in passing here: https://github.com/raspberrypi/linux/issues/3849#issuecomment-738295473)

Will let you know if I see any problems with this test firmware.

pelwell commented 3 years ago

There is a release candidate firmware available for testing here: https://drive.google.com/file/d/11szy6tlDFL5d7A6JdZLEwr0ZE1yQfNkE/view?usp=sharing

All being well it will be released in the next few weeks.

TamariusX commented 3 years ago

@pelwell, thank you very much. Fixed it for one RPi4 with the first fix - no crashes ever since Will test the release candidate right now with another one.

And yes, you all were right, Fritzbox 6660 here - Mesh was and is the culprit.

KnuckleBob commented 3 years ago

I'm having the same crashes on an RPi 3 B Rev 1.2 & WiFi goes away after some minutes or hours: "ieee80211 phy0: brcmf_fw_crashed: Firmware has halted or crashed"

Is the same chipset used on the RPi 4 & my older model?

Do I need to install the clm_blob & .bin file together?

pelwell commented 3 years ago

No - the 3B uses the BCM43438 which needs different firmware.

Predator83 commented 3 years ago

Hi pelwell, Thanks for digging into this! I am facing the same problem as you do and i would like to try the firmware you posted 2 days ago.

As I am really new to the Raspi, would you mind posting how to install? I know you did this earlier but when trying to follow these steps I completely messed up my Wifi. I think it was not completely clear to me which files to replace and which files to keep.

pelwell commented 3 years ago

This is how to install that test firmware:

  1. Follow this link and download the file there: https://drive.google.com/file/d/11szy6tlDFL5d7A6JdZLEwr0ZE1yQfNkE/view?usp=sharing
pelwell commented 3 years ago

[Pro Tip: - don't use Ctrl Enter when you mean Shift Enter] Let's try that again:

  1. Follow this link and download the file there: https://drive.google.com/file/d/11szy6tlDFL5d7A6JdZLEwr0ZE1yQfNkE/view?usp=sharing It will probably end up in ~pi/Downloads and be called brcmfmac43455-sdio.bin.
  2. In a terminal window, use cd to navigate to where the downloaded firmware is, e.g. cd ~pi/Downloads - it makes the instructions simpler.
  3. sudo mv /lib/firmware/brcm/brcmfmac43455-sdio.bin{,.orig} The funny punctuation at the end causes the filename to be repeated - once without .orig on the end and once with it.
  4. sudo cp brcmfmac43455-sdio.bin /lib/firmware/brcm

You can now reboot to try the new firmware.

Reverting to the old firmware is just a matter of moving the comma at the end of step 3: sudo mv /lib/firmware/brcm/brcmfmac43455-sdio.bin{.orig,}

Predator83 commented 3 years ago

Thanks for the pro tip :-) !

So you basically replace the "brcmfmac43455-sdio.bin" withe the downloaded version and back the original fiel up beforehand, right? And you only do that with this single file?

I guess what confused me in your description above is the following. You posted to proceed like this: 

pi@raspberrypi:~$ sudo mv /lib/firmware/brcm/brcmfmac43455-sdio.clm_blob{,.bak}
pi@raspberrypi:~$ sudo cp brcmfmac43456-sdio.clm_blob /lib/firmware/brcm/brcmfmac43455-sdio.clm_blob

There you are referring to the 43456 firmware (whis is just the file that you downloaded and renamed). But I do actually have a file in the /lib/firmware/brcm directory that is already named "brcmfmac43456-sdio.clm_blob".

pelwell commented 3 years ago

Yes - that installs the new firmware file. We have also changed the clm_blob file recently, but you can get the latest version of that by running sudo apt update and sudo apt install firmware-brcm80211. Note though that this may overwrite the test firmware you just installed, so it's best to run the apt commands first (or rerun the mv and cp again afterwards).

No - the 3B uses the BCM43438 which needs different firmware.

Just to save anybody else wasting time on this, it appears the file required for the BCM43438 on the RPi3 is brcmfmac43430-sdio.bin

I came from https://raspberrypi.stackexchange.com/questions/89803/access-point-as-wifi-router-repeater-optional-with-bridge - does anybody know if I need an update for the BCM43438 on the RPi3 (KnuckleBob suggests it has the same issue, it's not something I've experienced, but I'm doing a new build and my previous build appears to predate this issue). If so, is there an update for brcmfmac43430-sdio.bin and where would I find it?

djohnanderson commented 3 years ago

This new firmware fixes my problems with wifi on a Raspberry Pi 4 8Gb. From what I can tell this bug has been around for more than a year and affects both Raspberry Pi 3 and 4s. How could such an obvious bug go unfixed for so long????
