meta-bbb is a BSP layer to build yocto/poky images for Beaglebone Black boards. It only supports the Beaglebone black, neither Beaglebone white nor Beagleboards are supported. It was born from the need to generate a minimal network enabled system to use as a basis for custom deployments, as I was unable to generate a working system with the official meta-ti and meta-beagleboard layers. (According to google I was not alone with my problems ;-)

This layer is a implementation of Robert Nelsons tutorial at http://eewiki.net/display/linuxonarm/BeagleBone+Black

Kernel 3.13.1 u-boot 2013.10 with dedicated beaglebone black support beaglebone-black device tree sysvinit based works with any yocot/poky image recipe network enabled, dropbear ssh, avahi announcements SD-card image ready to dd onto a SD-card

No HDMI graphics support (neither at bootup nor later). Given the picky nature of the BBB HDMI Interface (see http://elinux.org/Beagleboard:BeagleBoneBlack_HDMI) and the fact that even with the official binary distribution it was more of an hit-or-miss I didn't bother. You'll need to pick up a serial cable to follow the bot process. Or just count to 30, ssh [email protected] and hope for the best ;-)

(Probably) no cape support

This layer depends on:

URI: git://git.openembedded.org/openembedded-core layers: meta branch: master

URI: git://git.yoctoproject.org/meta branch: master

I. Building the meta-bbb BSP layer II. Booting the images from separate download

Clone the repository to the top-level of your yocto build tree (or any other place, provided you know to configure that setup correctly,-), you can build a bbb image by adding the location of the meta-bbb layer to bblayers.conf, along with any other layers needed (to access common metadata shared between BSPs) e.g.:

yocto/meta-bbb \

To enable the bbb layer, add the bbb MACHINE to local.conf:

MACHINE ?= "bbb"

You should then be able to build a bbb image as such:

$ source oe-init-build-env $ bitbake bbb-basic-image

or you can build various standard yocto images such as:

core-image-basic core-image-lsb core-image-minimal core-image-minimal-dev

At the end of a successful build, you should have a several files in side build/tmp/deploy/images/bbb

zImage kernel 3.13.1 zImage-am335x-boneblack.dtb devicetree matching the kernel u-boot.bin u-boot bootloader MLO primary boot loader uEnv.txt u-boot configuration file core-image-lsb-bbb.tar.gz rootfs tarball core-image-lsb-bbb.ext3 root file system (mountable via loopback)

and a SD-card image named something like [IMAGENAME]-[TIMESTAMP].bbb-sdimg e.g. core-image-lsb-bbb-20140215103519.bbb-sdimg

The SD-card image can be directly written to an sd card using dd: sudo dd if=core-image-lsb-bbb-20140215103519.bbb-sdimg of=/dev/sde

CAUTION! Replace /dev/sde with the appropriate path to your sd card!

If you find you're getting corrupt images on the USB (it doesn't show the syslinux boot: prompt, or the boot: prompt contains strange characters), try doing this first:

dd if=/dev/zero of=/dev/sdf bs=1M count=512

Insert the sd card into your Beaglebone Black and power up the system. To follow the boot messages, you will need to connect to your BBB via serial cable and follow the output via terminal. Once powered up, your BBB will request an ip adress via dhcp and announce a ssh service bbb.local via avahi/bonjour/zeroconf. Use ssh [email protected] to connect to your BBB. The root password is not required (you might want to change that ;-)
