ascii/raspberry 3 wifi problem

Hello,

I have no wlan0 appearing after a fresh ascii install in RPi3.

# iwlist scan
lo        Interface doesn't support scanning.

eth0      Interface doesn't support scanning.
# ifup wlan0
Cannot find device "wlan0"
ifup: failed to bring up wlan0

I added brcmfmac to /etc/modules.

A devuan jessie on the same hardware (updated firmware) ran wifi OK. I tested with the distributed and updated firmware on ascii.

Thanks for the help.

Re: ascii/raspberry 3 wifi problem

Thanks for answering !
ifconfig as root only lists lo and eth0.
One funny thing is that when I remove/modprobe the brcmfmac module, syslog only says the module is registred, nothing about firmware.

Re: ascii/raspberry 3 wifi problem

# iwconfig 
eth0      no wireless extensions.

lo        no wireless extensions.
# lspci -nn
pcilib: Cannot open /proc/bus/pci
lspci: Cannot find any working access method.

(this is a rpi, no pci bus as far as I know)

Re: ascii/raspberry 3 wifi problem

syslog does not give very much info either :

Re: ascii/raspberry 3 wifi problem

Do you have raspi-config installed ?
If yes

 elect item 9, Advanced Options
Select item A5, Device Tree
Choose Yes
Reboot

if not

download this script from github
https://github.com/snubbegbg/install_raspi-config
and run it in terminal as root like so

sh install.sh

and follow the steps above

Re: ascii/raspberry 3 wifi problem

Thanks for the help.

I could install raspi-config, but the procedure didn't work (I tried twice), still no wlan0 or anything wireless else (only eth0 & lo).
By the way, A5 is not labelled "Device Tree" but SPI. Is it the same thing ?

Anyway, a SPI module is loaded

# lsmod |grep spi
spi_bcm2835            20480  0

and the devices are created

# ls -al /dev/spidev0.*
crw------- 1 root root 153, 0 Apr 24 21:15 /dev/spidev0.0
crw------- 1 root root 153, 1 Apr 24 21:15 /dev/spidev0.1

Re: ascii/raspberry 3 wifi problem

Maybe the builder of the PI3 images just doesn't read the forum?

—▶ https://git.devuan.org/sdk/arm-sdk/issues/28
Add a help cry there?

I was told in Devuan's IRC channel #devuan-arm that a solution exists but I did not get details.
*sigh!*

My two PI3s are still waiting for a solution too...
:-(

Exactly.   #devuan-arm (ping parazyd) and https://git.devuan.org/sdk/arm-sdk/issues/ are excellent places to catch his attention.

Re: ascii/raspberry 3 wifi problem

Here's a solution (found in https://git.devuan.org/sdk/arm-sdk/issues/28 and https://quantum2.xyz/2017/10/27/install … with-wifi/) :
get https://cs.wallawalla.edu/%7Estiltr/rpi3_4.14.26.tar.gz
extract archive, overwrite /boot with content of 4.14.26_boot.tar.gz
extract 4.14.26_modules.tar.gz into root partition (kernel modules)
get debian image from https://people.debian.org/~stapelberg/r … IEW.img.xz
mount image, copy firmware from root partition (/lib/firmware/brcm/*430*)
it should work :-)
