wlan0 don't exist with kernel 4.13.0-rc1-v7 in RPi3 #2132

dakota72 commented 7 years ago

Hi, I compilated the last kernel version for my rpi3 but The interface wlan0 is missing. the result of ifconfig eth0 Link encap:Ethernet HWaddr b8:27:eb:08:b7:16 inet addr:10.53.1.60 Bcast:10.53.1.255 Mask:255.255.255.0 inet6 addr: fe80::bd69:11c7:c80c:9e21/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1870 errors:0 dropped:13 overruns:0 frame:0 TX packets:1079 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:137445 (134.2 KiB) TX bytes:186082 (181.7 KiB)

wlan0 isn't in the list...why?

JamesH65 commented 7 years ago

Just tried this, seems to work fine. Are you sure all the modules and dtb stuff has been correctly installed on the SD card?

Note though that this is a very early 4.13, so support is limited and there are likely to be some issues.

@dakota72 Please provide a dmesg output.

I have followed this guide: http://ithink.ch/blog/2013/09/08/patching_the_linux_kernel_to_install_the_xin-mo_dual_arcade_driver_on_a_raspberry_pi.html

after compile I did this:

sudo cp arch/arm/boot/Image /boot/kernel_new.img mkdir ~/modules export MODULES_TEMP=~/modules make INSTALL_MOD_PATH=${MODULES_TEMP} modules_install mkdir ~/modules export MODULES_TEMP=~/modules make INSTALL_MOD_PATH=${MODULES_TEMP} modules_install cd /lib sudo cp -R ~/modules/lib/firmware/ . sudo cp -R ~/modules/lib/modules/ .

it's possible to my .config are wrong? which .config I must be used?

Looks like the mmc (not sdhost) driver isn't enabled.

Which repository did you use?

JamesH65 commented 7 years ago

The instructions referenced are talking about a 3.x series kernel, and are 4 years old. Might be worth checking these instructions..

https://www.raspberrypi.org/documentation/linux/kernel/building.md

dakota72 commented 7 years ago

it's possible that I was wrong a .config?

popcornmix commented 7 years ago

Always use the defconfig for that kernel tree - don't continue using an old config from an older (e.g. 4.9) kernel. i.e.

ARCH=arm make bcm2709_defconfig

Also make sure you 4.13 tree is up to date - a couple of days ago wifi wasn't working.

dakota72 commented 7 years ago

I updated 4.13 tree but the problem is the same... wlan0 don't exist. which is the patch for wifi?

pelwell commented 7 years ago

Your dmesg log is lacking any mention of mmc1, which is why WiFi isn't working. Build a vanilla RPi kernel following the instructions James linked to above (https://www.raspberrypi.org/documentation/linux/kernel/building.md) and prove that it works, at which point we know there is something wrong with your configuration.

That's looking much better. What do you get from dmesg | grep -E "(brcmfmac|wlan)"?

dakota72 commented 7 years ago

dmesg | grep -E "(brcmfmac|wlan)" nothing! :(

That all looks OK, which is odd. The grep in modules.alias shows that the brcmfmac module is registered, we already know that it is loadable and functional, and the MODALIAS line in the other output matches a value in the module so the window where things could be failing is now very small.

When the SDIO device is detected (which we know it is), the kernel generates an event that is intercepted by the userspace "udev" process. udev uses a large set of rules to determine how to handle each event, which in this case should result in an alias lookup and the brcmfmac module being loaded.

I may have overlooked something, but for now I'm going to say that threethings could be going wrong: 1) The kernel isn't emitting the right events. 2) The udev rule is missing or broken. 3) The brcmfmac module is blacklisted, which will prevent any automatic loading, requiring a manual modprobe to load it.

We can check for case 3 with:

grep brcmfmac /etc/modprobe.d/*

The others are harder.

grep brcmfmac /etc/modprobe.d/* /etc/modprobe.d/brcmfmac.conf:options brcmfmac debug=0x100000 /etc/modprobe.d/raspi-blacklist.conf:blacklist brcmfmac yess brcmfmac is blasklisted...but why?

I'm guessing your followed some tutorial, or perhaps you wanted to disable WiFi for an experiment. Well, it worked!

sudo rm /etc/modprobe.d/raspi-blacklist.conf
sudo reboot

It's worked. thanks so much for your support! :)
