[solved] wifi chipset not detected on rPi 3

[dervishe]

i've install gentoo on a raspberry Pi 3. The version of the kernel sources is 4.1.20-v7+. All works fine except for the wifi. When i load the module brcmfmac, it is loaded without complaint but the wifi chips isn't recognize nor detected. For the kernel config, i use the one from the latest raspbian /proc/config.gz.
(I tried also with 4.2 and 4.3 kernels but no more result)
As with the raspbian, the chip is detected, i know it works. I get the several firmware from the package linux-firmware and i've got the one i need /lib/firmware/brcm/brcmfmac4330-sdio.bin
releveant lsmod content:

Does dmesg say anything about your wifi? I think kernel 4.1 is too old for the wifi chip in the RPi 3.
Also, you need both brcmfmac43430-sdio.bin and brcmfmac43430-sdio.txt in /lib/firmware/brcm/

If it still doesn't work, try the precompiled 4.4 kernel image and modules from https://github.com/raspberrypi/firmware/tree/next

Thanks for your reply.
dmesg just say:

I know for a fact that the 4.4 precompiled image works, because I used it on my RPi 3 and it detected the wireless chip properly.

You download the kernel image from the github link above and place it in the boot partition.
Also you need the kernel modules from the modules/ directory and place them in /lib/modules

Thanks for the fast response.
I'll try it today.

thx

Marlo,

You also need the firmware and brcmfmac43430-sdio.txt in /lib/firmware/brcm/

those that do backups
those that have never had a hard drive fail.

I did this:
sudo apt-get update
sudo apt-get upgrade
sudo rpi-update
reboot

No wifi available.

I bought a new rp3, used the same MicroSD card aaaand
now it works again.

A hardware fault after 4 months use!

I finally succeeded to setup the wifi chipset with the firmwares:
brcmfmac4330-sdio.bin
brcmfmac43430-sdio.bin
brcmfmac43430-sdio.txt
