Edison
======
Build Instructions for U-Boot as main bootloader
------------------------------------------------
Simple you can build U-Boot and obtain u-boot.bin::
$ make edison_defconfig
$ make all
Updating U-Boot on Edison
-------------------------
By default Intel Edison boards are shipped with preinstalled heavily
patched U-Boot v2014.04. Though it supports DFU which we may be able to
use.
1. Prepare u-boot.bin as described in chapter above. You still need one
more step (if and only if you have original U-Boot), i.e. run the
following command::
$ truncate -s %4096 u-boot.bin
2. Run your board and interrupt booting to U-Boot console. In the console
call::
=> run do_force_flash_os
3. Wait for few seconds, it will prepare environment variable and runs
DFU. Run DFU command from the host system::
$ dfu-util -v -d 8087:0a99 --alt u-boot0 -D u-boot.bin
4. Return to U-Boot console and following hint. i.e. push Ctrl+C, and
reset the board::
=> reset
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. In short, after you
install all necessary dependencies and clone repository, it will look like this:
.. code-block:: sh
cd xFSTK
export DISTRIBUTION_NAME=ubuntu20.04
export BUILD_VERSION=1.8.5
git checkout v$BUILD_VERSION
...
Once you have built it, 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 find this `drive`_ helpful.
If it does, then you can download and unpack the Edison recovery image,
install dfu-util, reset your board and flash U-Boot like this:
.. code-block:: sh
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
.. code-block:: none
XFSTK Downloader Solo 1.8.5

.Intel SoC Device Detection Found
Parsing Commandline....
Registering Status Callback....
.Initiating Download Process....
.......(lots of dots)........XFSTK-STATUS--Reconnecting to device - Attempt #1
.......(even more dots)......................
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
10 seconds after that should see the above message again and then within a few
seconds U-Boot should start on your board:
.. code-block:: none
