Installation instructions for Intel Edison device
-------------------------------------------------
At the moment, the meta-eca with Edison device has
been tested with Yocto dizzy release.
$ mkdir yocto
$ cd yocto
$ git clone git://git.yoctoproject.org/poky
$ cd poky
$ export YOCTO=`pwd`
$ git checkout -b dizzy origin/dizzy
$ git clone git://git.openembedded.org/meta-openembedded
$ cd meta-openembedded
$ git checkout -b dizzy origin/dizzy
$ cd ..
$ git clone git://git.yoctoproject.org/meta-eca
Get the latest edison-src.tgz file from download center at
https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&keyword=edison
As of this writing, the latest tgz file is called
edison-src-rel1-maint-rel1-ww42-14.tgz
$ tar xvfz edison-src-*.tgz
You need to apply patches to edison-src.
$ cd edison-src
$ patch -p1 < $YOCTO/meta-eca/patches/edison/edison-src.diff
$ cd $YOCTO
$ . oe-init-build-env build-edison
$ cd conf
Edit bblayers.conf file and add these layers to BBLAYERS variable,
if your name is not "user", then fix the path accordingly.
/home/user/yocto/poky/meta-eca/meta-eca
/home/user/yocto/poky/meta-eca/meta-eca-bsp
/home/user/yocto/poky/meta-openembedded/meta-oe
/home/user/yocto/poky/meta-openembedded/meta-systemd
/home/user/yocto/poky/meta-openembedded/meta-networking
/home/user/yocto/poky/meta-openembedded/meta-python
/home/user/yocto/poky/meta-openembedded/meta-ruby
/home/user/yocto/poky/edison-src/device-software/meta-edison
/home/user/yocto/poky/edison-src/device-software/meta-edison-distro
Edit local.conf file (use the correct path when setting EDISONREPO_TOP_DIR
variable)
* set BB_NUMBER_THREADS and PARALLEL_MAKE accordingly to your machine
capabilities (optional)
* set your target to MACHINE ?= "edison"
* set DISTRO ?= "eca"
* add following BBMASK lines to ignore conflicting recipes
BBMASK = "meta/recipes-connectivity/bluez/bluez4*"
BBMASK .= "|meta/recipes-bsp/u-boot/"
BBMASK .= "|meta-openembedded/meta-systemd/oe-core/recipes-connectivity/bluez/bluez4*"
BBMASK .= "|meta-edison/recipes-kernel/linux/"
BBMASK .= "|meta-edison-distro/recipes-support/i2c-tools/"
BBMASK .= "|meta-edison-distro/recipes-core/busybox/"
BBMASK .= "|meta-edison-distro/recipes-connectivity/wpa_supplicant/"
BBMASK .= "|meta-edison-distro/recipes-connectivity/ofono/"
BBMASK .= "|meta-edison-distro/recipes-connectivity/bluez5/"
BBMASK .= "|meta-edison-distro/recipes-connectivity/libpcap/"
BBMASK .= "|meta-edison-distro/recipes-bsp/u-boot/"
BBMASK .= "|meta-edison-distro/recipes-support/tcpdump/"
* add EDISONREPO_TOP_DIR = "/home/user/yocto/poky/edison-src"
If you want to build the Internet-of-Things version of ECA, then add
/home/user/yocto/poky/meta-eca/meta-iot
to bblayers.conf and also add
DISTRO_FEATURES_append = " internet-of-things"
to local.conf file.
Then build the distro
$ cd $BUILDDIR
$ bitbake eca-image
If you see some build errors for neard, then do this
$ bitbake neard
$ bitbake eca-image
If the build succeeds, the result image can be found at
tmp-glibc/deploy/images/edison
Make sure you have USB Device Firmware Upgrade (DFU) packages
installed in your system. For Fedora the package is called dfu-util.
Set the parameter to eca-postBuild.sh script to be the real location
of edison-src directory.
$ cd $BUILDDIR/tmp-glibc/deploy/images/edison
$ $YOCTO/meta-eca/scripts/edison/eca-postBuild.sh $YOCTO/edison-src
WARNING: The next command will flash the Edison board. It is possible
that the flashing will fail which might brick your Edison
device. If you are not an expert, do not try to flash the device.
+--------------------------------------------------------------+
| I will not be responsible if you mess things up so I suggest |
| that you do not try the following. You have been warned!!! |
+--------------------------------------------------------------+
If you continue and something will fail with the flashing,
you can try to recover by first installing the xFSTK package
from http://sourceforge.net/projects/xfstk/ and then running
"sudo ./flashall --recover" command (I have not tested this thou).
Then start flashing.
$ cd toFlash
$ sudo ./flashall
Then connect Edison to your host via lower right hand side USB connector
in Edison breakout board, and wait the flashing to finish.
The device will now flash itself and reboot several times.
Please wait until you see login prompt.
KNOWN ISSUES
------------
If you use "connmanctl" command and press Control-C to exit its command prompt,
then it is possible that the terminal stays in weird state and you do not see
any keypresses. Just type "stty sane^J" blindly and the terminal should be reset
to initial state (^J means that you press Control-J key). You should exit
the connmanctl shell by typing "exit" or pressing Control-D to avoid this issue.
If you want to reflash but the device refuses to load the firmware when booting.
Login to system and type "reboot ota" in Edison, and type "sudo ./flashall" in
another terminal in your host. This will cause the system to flash the device
again.
