How to install the SPEAr Linux Support Package (LSP2.3)

The SPEAr Linux Support Package (LSP2.3) is needed to develop software running on a

SPEAr target boards when embedded Linux is to be used as the target’s operating system.

The SPEAr Linux Support Package (LSP2.3) is not needed in order to use the software pre-

flashed on SPEAr boards or to update the Flash memory with default predefined contents.

Note:

The SPEAr Linux Support Package (LSP2.3) software must be installed on a Linux PC.

Windows® PCs are not supported.

until you have read and agreed to the following terms and conditions. The use of the

Licensed Software implies automatically the acceptance of the following terms and

conditions.

Connect to the www.st.com and navigate to the product pages for embedded

microprocessors. The link for downloading the SPEAr Linux Support Package

(LSP2.3) can be found by navigating to the web page containing the literature and other

resources for the related SPEAr device (product pages).

Note:

To download the file, you have to use a browser running on the Linux development PC.

Click on link below to download the initial installation script to your Linux PC: install

script download:

ftp://stlinux.com/pub/stlinux/2.3/install

Run the downloaded script on your Linux PC as follows: ./install all-arm-spear

This procedure automatically starts the overall download and installation of the

required software components (remotely available as RPM packages). The entire

procedure takes several minutes, depending on the network speed. The distribution is

installed by default under path /opt/STM.

When the installation is completed, configure the Linux shell environment as follows:

export PATH=$PATH:.:/opt/STM/STLinux-2.3/devkit/arm/bin:/opt/STM/STLinux-

2.3/host/bin

export CROSS_COMPILE=arm-linux-

In order to preserve this configuration, the same commands should be also be put in a

bash shell initialization file.
