meta-debian is a set of recipes (metadata) for the poky build system, which allows cross-building GNU/Linux images using Debian source packages. By enabling meta-debian, you can cross-build a small GNU/Linux image with Debian sources for multiple architectures.
The main purpose of meta-debian is to provide reference Linux distribution for embedded systems satisfying the following needs.
- Long-term support
- Stability
- Wide embedded CPU support
- Customizability
Currently, the following software versions are supported in meta-debian.
- Source code: Debian GNU/Linux 8 (jessie)
- Build system: Yocto Project 2.0 (jethro)
Install essential packages poky requires into your host system according to http://www.yoctoproject.org/docs/2.0/ref-manual/ref-manual.html#intro-requirements
$ sudo apt-get install git tar python
$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socatNOTE: The following three packages have version limitation
- git: 1.7.8 or greater
- tar: 1.24 or greater
- python: 2.7.3 or greater not including Python 3.x
Setup repositories.
$ git clone git://git.yoctoproject.org/poky.git
$ cd poky
$ git checkout jethro
$ git clone https://github.com/meta-debian/meta-debian.git
$ cd meta-debian
$ git checkout jethro
$ cd ../../Setup build directory.
$ export TEMPLATECONF=meta-debian/conf
$ source ./poky/oe-init-build-envYou can change the target machine by setting MACHINE variable in conf/local.conf to one of the following machines.
- qemux86 (default)
- qemux86-64
- qemuarm
- qemuarm64
- qemuppc
- qemumips
For example, the target machine is set to QEMU ARM by adding the following difinition to conf/local.conf.
MACHINE = "qemuarm"
Now, the build system is ready. Build Linux kernel and the minimal rootfs by the following command. It takes a while to complete (more than 30 minutes).
$ bitbake core-image-minimalRun the built Linux on QEMU.
Please replace ${MACHINE} by the target machine you selected in the above step.
$ runqemu ${MACHINE} nographicOnly if MACHINE is qemuarm, the console should be set to the correct serial device.
$ runqemu qemuarm nographic bootparams="console=ttyAMA0"After boot, you can login as root without password.
If you'd like to reduce the time of bitbake, please refer to https://github.com/meta-debian/meta-debian-docker.
