Brcmfmac failed on Pi3 and Pi Zero

For Developers

Hello.
I am new in this forum, and I have a problem building images for Raspberry PI3 and PI Zero.
When I build the firmware all seems correct, but it is not possible to get the on Board wifi working.

When I register (modprobe brcmfmac) I get the following error in dmesg:

Has anyone a solution for this?

Thanks Marc.

I tried now different solutions and can not get wifi working.
I build 2 clean images brcm2808-brcm2809 and brcm2808-brcm2810 clean from 'git clone' on master branch.
Both Images show the errors above in dmesg. I tried the image on pi3b and pi-Zero-w.
Has anyone OpenWrt running on this Systems and check?
Thanks Marc

I can confirm the issue. Until we can push a fix, you can either build master at commit e9d92bf1e1af71ff19e4cdc753de3f65963c58a5 after deleting package/kernel/mac80211/patches/brcm/864-brcmfmac-do-not-use-internal-roaming-engine-by-default.patch, or use 18.06.

I reported the issue upstream and have a patch to revert the change that broke wifi in my staging tree.

Can you help me solve this problem and fix it? Thank you for your help.

Hi. I rolled Bach tons further version of openwrt sources an that solves the problem

10

from 'git clone' on master branch will be ok?? On my raspberry 3B+ work all very well but Zero WH don't work...

11

Hi the master branch had the problems so i got the advice to use the openwrt-18.06 brench,

here i had no problems.

git branch

master

  • openwrt-18.06
