########
|
|
|
|
This document provides brief instructions about building and booting Genode
|
|
with the 'base-hw' repository. The 'base-hw' repository provides an
|
|
implementation of the Genode core that runs directly on hardware, without an
|
|
intermediate third-party kernel. It supports a limited range of target boards.
|
|
For further target specific informations, have a look at
|
|
'<GENODE_DIR>/base-hw/doc/<TARGET>.txt' where '<TARGET>'
|
|
is one of the following:
|
|
|
|
'pbxa9' - Realview PBXA9
|
|
'vea9x4' - Versatile Express A9X4
|
|
'imx31' - Freescale i.MX31
|
|
'panda' - PandaBoard A2
|
|
|
|
|
|
Prerequisites
|
|
#############
|
|
|
|
To build Genode you need to download and install the tool-chain used by Genode.
|
|
Have a look at this page:
|
|
|
|
:[http://genode.org/download/tool-chain]:
|
|
Genode tool-chain
|
|
|
|
If you want to use the so called run-scripts in Genode, a mechanism that
|
|
automates building, integration and testing of components, you have to install
|
|
the following, additional package:
|
|
|
|
! apt-get install expect
|
|
|
|
If you want to examine the examples that are given in this document, you will
|
|
need Qemu for ARM emulations to run them on your machine:
|
|
|
|
! apt-get install qemu-kvm-extras
|
|
|
|
|
|
Building Genode to run directly on hardware
|
|
###########################################
|
|
|
|
The current version of the Genode source code is available at this page:
|
|
|
|
:http://genode.org/download/repository:
|
|
Donwloading the Genode source code
|
|
|
|
Now, go to a directory where you want the Genode build directory to
|
|
remain. Use the helper script in the 'tool' directory of the Genode
|
|
source tree to create the initial build environment. You need to state the
|
|
build directory you want to create, and the hardware target to run Genode on.
|
|
|
|
! <genode-dir>/tool/create_builddir hw_<TARGET> BUILD_DIR=<build-dir>
|
|
|
|
Where '<TARGET>' is one of the following, depending on the hardware system
|
|
you aim at:
|
|
|
|
'pbxa9' - Realview PBXA9
|
|
'vea9x4' - Versatile Express A9X4
|
|
'imx31' - Freescale i.MX31
|
|
'panda' - PandaBoard A2
|
|
|
|
Please notice that not all of these targets might be emulateable with Qemu.
|
|
To be on the safe side use 'pbxa9'. For informations about how to boot
|
|
'base-hw' images on real hardware have a look at
|
|
'<GENODE_DIR>/base-hw/doc/<TARGET>.txt'.
|
|
|
|
Now, go to the newly created build directory make a test:
|
|
|
|
! cd <build-dir>
|
|
! make run/nested_init
|
|
|
|
This will build the Genode components that are needed to run a simple test
|
|
with 3 nested init programs, and than execute it via Qemu.
