===== Build a FreeBSD image =====

  - Fetch a devicetree image

<code>
fetch https://builds.96boards.org/snapshots/dragonboard410c/linaro/ubuntu/latest/dt.img
</code>

===== Load a FreeBSD kernel using fastboot =====

  - You will need the Android fastboot utility available in the android-tools-fastboot package:

<code>
pkg install android-tools-fastboot
</code>

  - Follow the 96boards instruction to [[https://github.com/96boards/documentation/wiki/Dragonboard-410c-Installation-Guide-for-Linux-and-Android#create--install-a-rescue-image|create an SD card with a rescue image]]. For example:

<code>
fetch 'http://builds.96boards.org/releases/dragonboard410c/linaro/rescue/latest/dragonboard410c_sdcard_rescue*.zip'
tar xvf dragonboard410c_sdcard_rescue\*.zip
sudo dd if=db410c_sd_rescue.img of=/dev/da0 bs=64k
</code>

Install the SD card and set the ''%%SD boot%%'' switch on the bottom of the %%DragonBoard%% to ''%%on%%'' and turn on the power.

  - Use fastboot to boot the image. Caution: ''%%/sbin/fastboot%%'' is a link to ''%%/sbin/reboot%%'', so be sure that you execute the correct one!
