<h3>What works</h3>
<ul>
<li>Compiling the LineageOS kernel</li>
<li>SSH</li>
<li>Booting</li>
<li>Flash light</li>
<li>Battery</li>
<li>Weston + Touchscreen (with <a href="https://github.com/postmarketOS/pmbootstrap/pull/66">ugly hacks</a> and the <a href="https://github.com/postmarketOS/pmbootstrap/issues/54">red screen bug</a>)</li>

<h3>What does not work</h3>
<ul>
<li>Proprietary video driver (<a href="https://github.com/postmarketOS/pmbootstrap/issues/29">#29</a>)</li>
<li>Flashing the compiled LineageOS kernel via pmbootstrap (<a href="https://github.com/postmarketOS/pmbootstrap/issues/35">#35</a>)</li>
<li>WiFi (firmware needed)</li>
<li>Front led</li>
</ul>

<p>There is also a bug and the screen is not updated. Workaround: login using ssh and run the following command:</p>
<pre class="codehilite"><code>ssh user@172.16.42.1
sudo su
while [ ! ]; do cat /sys/class/graphics/fb0/modes > /sys/class/graphics/fb0/mode; done</code></pre>
