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
