======
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
