INTRODUCTION

This project is a demonstration how to simulate custom hardware using qemu. The custom hardware will have the ability to be used as test environment for automatic (scripted) tests.

USAGE

The general usage is:

qtb.sh command

To check your environment:

qtb.sh info

If you like to change a specific variable:

QEMU_PATH=$HOME/qemu/bin ./qtb.sh info

BUILDING FROM SOURCE

Source packages are expected to be in the package directory. It is not implemented (yet) to automatically download any pacakges, they are expected to be present.

TOOLCHAIN

The toolchain can be unpacked using the command:

qtb.sh build toolchain

This unpacks the precompiled toolchain (compiled for Linux x86). If you like to build the toolchain from scratch:

qtb.sh build toolchain-scratch

BUSYBOX

This requires the presence of a cross-toolchain.

Build it with:

qtb.sh build busybox

Please note: this does build the busybox, it does not install it anywhere.

LINUX

Currently there are two kernels supported to be built by the scripts:

• versatile
• versatile-bbv

Build the desired kernel:

qtb.sh build kernel-versatile

or

qtb.sh build kernel-versatile-bbv

BUILD AND START THE DEMOS

The toolbox can also be used to start the demos. After building all necessary packages you may build and start the examples:

qtb.sh build demo ext2

Then start the example:

qtb.sh start ext2

Please note: for most demos to be built, sudo is used. Therefore you will need to specify the password in order to build the demo. Starting it will not require superuser privileges.

MISCELLANEOUS

It is possible to use the scripts to download necessary packages without building them. This feature is to prevent to add third party packages to the repository, but not to have to copy all those packages offline. Using this feature you will only use whats within the repository to use this project.

Obtain information about downloading pacakges using:

qtb.sh download info

The toolchain building script (uses crosstool-NG) also has a package download mechanism.
