USB flasher first screen

In the SPEAr Flashing utilities window, select the target device (SPEAr300 in the

example).

Click on the Connect button.

The PC now asks for a new driver.

Select the following path: c:\flashing_util\Setup\g_serial.inf

A new COM port should be now visible inside Windows Device Manager. The same COM

port must be used in next tasks with USB flasher.

The USB flasher tool is now ready for normal operation.

2.8.2

Installing the Flash images

For each evaluation board, default binary images for serial NOR Flash are available on ST

Web site (see Figure 2.8.1 above) for usage in combination with the USB flasher tool.

To install the Flash images, download the ZIP file for a specific evaluation board and extract

its contents under the same folder as the one used for USB Flasher.

For example, if you use the EVALSPEAR300 evaluation board, the ZIP file with the Flash

images should be extracted to the following path:

c:\flashing_util\evalspear300_Flash_images

The subfolder should contain 4 binary images (xloader, U-Boot, kernel and default root

filesystem) as well as a USB flasher configuration file, for example, s300_defconfig.conf
