###meta-bananapi

Un-Official OpenEmbedded layer for bananapi boards.

Due to the linux sunxi did not merge the kernel and uboot changes made by Lemaker.

So we make some changes on meta-sunxi and add this new layer to make OE works for bananapi.

This layer depends on the additional layer:

meta-sunxi: https://github.com/xleng/meta-sunxi

meta-openembedded: git://git.openembedded.org/meta-openembedded

Tested with core-image-minimal based on yocto 1.6

###Build minimal image

The following steps has just been tested under ubuntu 12.04 and it may also works on others *nix like OS.

####Install the essential packages

$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib
build-essential chrpath libsdl1.2-dev xterm

####Get poky-daisy-11.0.0

$wget http://downloads.yoctoproject.org/releases/yocto/yocto-1.6.1/poky-daisy-11.0.1.tar.bz2

$tar xvjf poky-daisy-11.0.0.tar.bz2

$cd poky-daisy-11.0.0

####Get meta-sunxi

$git clone https://github.com/xleng/meta-sunxi.git

####Get meta-bananapi

$git clone https://github.com/xleng/meta-bananapi.git

####Get meta-openembedded

$git clone -b daisy https://github.com/openembedded/meta-openembedded.git

####Set compile config

$source ./oe-init-build-env

Add meta-sunxi, meta-bananapi, meta-oe layers to ./conf/bblayer.conf, and it wil be something like this:

$cat ./conf/bblayers.conf

# LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf

# changes incompatibly LCONF_VERSION = "6"

BBPATH = "${TOPDIR}" BBFILES ?= ""

BBLAYERS ?= " \ /home/john/opensource/yocto/poky-daisy-11.0.0/meta \ /home/john/opensource/yocto/poky-daisy-11.0.0/meta-yocto \ /home/john/opensource/yocto/poky-daisy-11.0.0/meta-yocto-bsp \ /home/john/opensource/yocto/poky-daisy-11.0.0/meta-sunxi \ /home/john/opensource/yocto/poky-daisy-11.0.0/meta-bananapi \ /home/john/opensource/yocto/poky-daisy-11.0.0/meta-openembedded/meta-oe \ " BBLAYERS_NON_REMOVABLE ?= " \ /home/john/opensource/yocto/poky-daisy-11.0.0/meta \ /home/john/opensource/yocto/poky-daisy-11.0.0/meta-yocto \ "

the parent path of poky maybe different in your pc.

And change the machine type to bananapi in ./conf/local.conf

MACHINE ??= "bananapi"

####Run compile command $bitbake core-image-minimal

This will cost a lot of time in your first compile, it will donwload the sources form internet and then compile the sources, so be patient with it.

You will get a image file under './tmp/deploy/images/bananapi/core-image-minimal-bananapi.sunxi-sdimg'.

Flash this image file with your tools to sd card to boot the system.
