+Updating U-Boot using xFSTK
+---------------------------
+
+You can also update U-Boot using the xfstk-dldr-solo tool if you can build it.
+One way to do that is to follow the `xFSTK`_ instructions. You may need to use
+a virtual machine running Ubuntu Trusty. Once you have built it and installed
+libboost-all-dev, you can copy xfstk-dldr-solo to /usr/local/bin and
+libboost_program_options.so.1.54.0 to /usr/lib/i386-linux-gnu/ and with luck
+it will work. You might fine this `drive`_ helpful.
+
+If it does, then you can download and unpack the Edison reocovery image,
+install dfu-util, reset your board and flash U-Boot like this::
+
+   $ xfstk-dldr-solo --gpflags 0x80000007 \
+      --osimage u-boot-edison.img \
+      --fwdnx recover/edison_dnx_fwr.bin \
+      --fwimage recover/edison_ifwi-dbg-00.bin \
+      --osdnx recover/edison_dnx_osr.bin
+
+This should show the following
+

+You have about 10 seconds after resetting the board to type the above command.
+If you want to check if the board is ready, type:
+
+.. code-block:: none
+
+  lsusb |egrep "8087|8086"
+  Bus 001 Device 004: ID 8086:e005 Intel Corp.
+
+If you see a device with the same ID as above, the board is waiting for your
+command.
+
+After about 5 seconds you should see some console output from the board:
+
+.. code-block:: none

+  After another 10 seconds the xFSTK tool completes and the board resets. About
