Instructions for BeagleBoneBlack device
---------------------------------------
You might want to check from README.md file what poky and meta-oe
revisions are supported. This build has been tested with Yocto dizzy
release.
$ mkdir yocto
$ cd yocto
$ git clone git://git.yoctoproject.org/poky
$ cd poky
$ 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
$ 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-python
/home/user/yocto/poky/meta-openembedded/meta-ruby
Edit local.conf file
* set BB_NUMBER_THREADS and PARALLEL_MAKE accordingly to your machine
capabilities (optional)
* 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.
