xFSTK sources got a new home under Edison Firmware Group on GitHub [1]. Update Intel Edison documentation accordingly. While here, fix couple of typos.

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
|
|

|
|
|
|
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:
|
