Zero Wifi breaks randomly

Zero Series
1

I recently got a radxa Zero 1GB and installed the latest image: “radxa-zero-debian-buster-xfce4-arm64-20211121-0245-mbr.img”. Wifi lasts for a few hours and then breaks.
I’ve also tried the following with no luck:

rmmod brcmfmac
modprobe brcmfmac

Here is the log:

dmesg | grep brcmfmac

Please download the image from here. The one you were using is pretty old by now.

Same issue.

Hi @psyc, have you read through this thread?

More specifically have you verified wifi powersave is off?

While the error output is different, the timing is suspect.

Hope this helps!

error -2 or (err=-2) means you are missing files. Two specific ones: brcmfmac43430-sdio.radxa,zero.txt and brcmfmac43430-sdio.clm_blob.

Not sure if adding those files will fix your wifi problem, but that’s the first thing I would try.

The files aren’t there…where would I get them?

I also turned off powersave last night, I’ll see how that goes.

I don’t have the 1GB model, nor do I have that specific year firmware 2016, but I do have what I believe should work on my github. You are more than welcome to test it: git clone -b radxa https://github.com/pyavitz/firmware.git

Make sure to backup the current firmware you have in place before over writing it. sudo cp -r /lib/firmware/brcm /lib/firmware/brcm.orig

So interestingly enough, turning off wifi powersave seems to have solved the issue. The error is still there, but slightly different after adding the file it was looking for.

From what I recall the clm_blob is supposed to be inside the bin file, so that it strange.
