<h3>What works</h3>
<ul>
<li>Compiling the kernel</li>
<li>Building a base image</li>
<li>Fastboot flash</li>
<li>SD card install</li>
</ul>
<h4>Current Build / Boot Process</h4>
<p>Build and install to SD card:</p>
<pre class="codehilite"><code>$ ./pmbootstrap.py build device-mozilla-flame
$ ./pmbootstrap.py build linux-mozilla-flame --arch=armhf
$ ./pmbootstrap.py install --sdcard /dev/mmcblkX
$ ./pmbootstrap.py flasher export $SOMEDIR</code></pre>
<p>Now we can one-time flash the boot image:</p>
<pre class="codehilite"><code>$ flashboot boot $SOMEDIR/boot.img</code></pre>
<h3>Known Issues</h3>
<h4>Unknown chunk type</h4>
<p><code>mozilla-flame.img</code> cannot be flashed to either the <code>system</code>/<code>userdata</code> partitions due to bootloader limitations (probably because the system image is larger than the max download size and it forces the download into sparse mode, which is handled badly.)</p>
<pre class="codehilite"><code>$ fastboot flash userdata flame/mozilla-flame.img
target reported max download size of 301989888 bytes
erasing 'userdata'...
OKAY [ 1.254s]
sending sparse 'userdata' 1/2 (288781 KB)...
OKAY [ 10.018s]
writing 'userdata' 1/2...
FAILED (remote: Unknown chunk type)
finished. total time: 11.275s</code></pre>
<p>Workaround is to install to SD card.</p>
