Anyone got the on board wifi working on Raspberry Pi 3 with CentOS7 AArch64?

Postby frankofgdc » 2017/08/14 08:11:42

Raspberry Pi 3 has on board wifi and bluetooth. I bought it soon after release, but never got the wifi/bluetooth working.
Yesterday, I want to setup a personal server at home, and I remember my pi 3.

I followed this tutorial and got CentOS 7 AArch64 running on Pi 3.
After those steps, there was error message in dmesg about brcmfmac43430-sdio.bin I checked in /lib/firmware/brcm/ and cannot find this file.
I searched to this github repository and copied brcmfmac43430-sdio.bin to /lib/firmware/brcm/

After reboot, I can see wlan0 with nmcli d command, however, it appears to be unmanaged

Code: Select all

$ nmcli d
DEVICE  TYPE      STATE      CONNECTION
eth0    ethernet  connected  eth0
lo      loopback  unmanaged  --
wlan0   wifi      unmanaged  --


I checked dmesg again, and only this line is related to it, which appears to be normal:
[ 7.425458] brcmfmac: Firmware version = wl0: May 27 2016 00:13:38 version 7.45.41.26 (r640327) FWID 01-df77e4a7

I also tried 'nmcli radio wifi off' and 'nmcli radio wifi on', still nothing happens. I'm stuck in here. Anyone can help about it? Has anyone got it working with CentOS, even with the 32 bit version?

I'd be really surprised if you did. The aarch64 architecture doesn't include the rpi3 - for that you need armhfp.

The Cortex-A53 processor cores on RPi3 are AArch64 compatible.

That's as maybe but the rpi3 images we provide are armhfp.

I didn't use the rpi3 image, I used "CentOS-7-aarch64-rolling.img.xz" plus linux core source code from raspberry pi github. Just can't make the wifi working.

Yes but there is no rpi3 image for aarch64 as yet. There may be in the future but for rpi3, currently what we ship and intend for use on the rpi3 is the armhfp image.

I got your point, just wonder if anyone has made the on board wifi working. Is it an easy task with armhfp image? Maybe I will try with armhfp image later.

Hi, just to update, I tried with rpi3 img today. On board wifi is working fine after download firmware. It seems the aarch64 kernel I compile by myself is not working with wifi driver. Maybe some modifications to kernel source code is necessary in order to get the aarch64 kernel work with the on board wifi.
