<p>If the boot process seems to hang after the following messages
(messages not necessarly exactly similar, depending on the list of
packages selected):</p>
<pre>Freeing init memory: 3972K
Initializing random number generator... done.

<p>then it means that your system is running, but didn't start a
shell on the serial console. In order to have the system start a
shell on your serial console, you have to go in the Buildroot
configuration, <code>Target options</code>, enable <code>Generic
serial port config</code>, and select the serial port and speed
you would like to use for the shell. This will automatically tune
the <code>/etc/inittab</code> file of the generated system so that
a shell starts on the correct serial port.</p>
