Instructions for BeagleBoneBlack device
---------------------------------------

You might want to check from README.md file what poky and meta-oe
revisions are supported. Usually HEAD version work ok but if it
does not, then you can use the tested version mentioned in that file.

$ mkdir yocto
$ cd yocto
$ git clone git://git.yoctoproject.org/poky
$ cd poky
$ git clone git://git.openembedded.org/meta-openembedded
$ git clone git://git.yoctoproject.org/meta-eca
$ export YOCTO=`pwd`
$ git clone git://github.com/beagleboard/meta-beagleboard.git
$ . oe-init-build-env build-bbb
$ 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-beagleboard/common-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-ruby

Edit local.conf file

* set BB_NUMBER_THREADS and PARALLEL_MAKE accordingly to your machine
  capabilities
* set your target to MACHINE ?= "beaglebone"
* set DISTRO ?= "eca"
* add BBMASK = "meta/recipes-connectivity/bluez/bluez4*|meta-openembedded/meta-systemd/oe-core/recipes-connectivity/bluez/bluez4*"


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 the build succeeds, the result image can be found at
tmp-eglibc/deploy/images/beaglebone

Partition and format an SD card:

# fdisk -lu /dev/mmcblk0

Disk /dev/mmcblk0: 3951 MB, 3951034368 bytes
255 heads, 63 sectors/track, 480 cylinders, total 7716864 sectors
Units = sectors of 1 * 512 = 512 bytes

        Device Boot      Start         End      Blocks  Id System
/dev/mmcblk0p1   *          63      144584       72261   c Win95 FAT32
/dev/mmcblk0p2          144585      465884      160650  83 Linux

# mkfs.vfat -F 16 -n "boot" /dev/mmcblk0p1
# mke2fs -j -L "root" /dev/mmcblk0p2

The following assumes the SD card partition 1 and 2 are mounted at
/media/boot and /media/root respectively. Removing the card and reinserting
it will do just that on most modern Linux desktop environments.

$ sudo -s
# cd tmp-eglibc/deploy/images/beaglebone
# cp MLO /media/boot/
# cp u-boot.img /media/boot/u-boot.bin
# cp uImage /media/boot/
# tar x -C /media/root -f eca-image-beaglebone.tar.gz
# tar x -C /media/root -f modules-beaglebone.tgz
# sync

Then eject the SD card, insert it to your Beaglebone and boot.
