Updating the pre-flashed software

This section focuses on updating the contents of serial NOR Flash with default binary

images available on ST Web site. It also focuses on updating NAND Flash.

Updating the contents of Flash memory on SPEAr evaluation boards is a recommended

step. It is possible to update the pre-flashed software delivered by default with a SPEAr

evaluation board without installing the STLinux distribution.

The procedure for the update involves the installation and use of the USB Flasher tool

provided by ST.

This tool is a graphical interactive application, which can be downloaded from ST company

site, which also provides download for updated binary images (for each evaluation board

type) to be used with the USB Flasher. The use of the USB Flasher for other purposes and

scenarios is explained in the help pages embedded in the tool itself.

2.9.1

Before setting up the flasher tool, download and install an updated TCL package. The
