title: Enabling wlan on Raspberry Pi 3 bare linux
body: <p>I have built the linux system for my RPi3 using buildroot. It boots properly and I can access the wired connection properly. However, I am stuck with enabling the wlan.</p>
  
  <p>Here is what I have done so far.
  Built the filesystem using buildroot:</p>
  
  <pre><code>make raspberrypi3_defconfig
  make
  </code></pre>
  
  <p>After booting linux successfully I followed <a href="https://delog.wordpress.com/2014/10/10/wireless-on-raspberry-pi-with-buildroot/" rel="nofollow">this</a> link to enable wlan.
  As the author of the post mentions, I had to select some of the wireless related packages by running <code>make linux-menuconfig</code>. But when I did run it, these packages were already selected. 
  I then ran <code>make menuconfig</code> and selected wpa_supplicant and other packages.</p>
  
  <p>Now, when I boot the RPi3, wlan0 is not listed when I run <code>ifconfig -a</code>. I googled it a bit and found that there should be folder named <code>wlan0</code> under <code>/sys/class/net/</code>. But I can only find <code>eth0</code> and <code>lo</code></p>
  
  <p>Kindly guide me on how to get the wlan working. dmesg log is posted <a href="http://pastebin.com/W72GaUg2" rel="nofollow">here</a></p>
