How-To install Armadeus Software Development Kit for Linux/Window$

Forewords

Before writing your first program, you will need to build the required tools to compile it on your host system (cross compilation). The gnu toolchain will be used.

Lexical

• Binutils: several GNU utilities to generate executable files
• Buildroot / Busybox: "swiss knife" of the embedded Linux
• GCC: GNU C compiler
• GDB: GNU debugger
• RootFS: root filesystem. Filesystem which will be installed on your target and used by Linux as root ("/") mountpoint.
• UBoot: Bios / Bootloader

Recommended System Requirements

• HD free space: at least 1.5GB
• 1Go RAM is preferable
• 2GHz processor with a 533MHz FSB
• High speed Internet connection (1Mbits)

With these settings, you will get a complete toolchain, Linux and the RootFS in about 1h30.

Toolchain installation on Linux systems

Window$ installation

After a performance test with VMWare, it is clear that Cygwin will be no more supported. We have observed quite a factor 2 in terms of compilation improvements.

• What is VMWare ?: it is a virtualization tool able to run a standard Linux distrib on a native Windows system or Windows on a Linux native system.
• VMWare player is free. VMWare desktop (used to create the first virtual system) is available for evaluation. You need it only one time.

It has to be noted that a VMWare will require more disk space as cygwin because a complete Linux distribution will be installed.
