Welcome to Tegra
This document describes how to setup a Tegra devkit and flash (install) the Android OS to it.
Tegra devkits can be flashed from either Windows or Linux host PCs. Both are described in this
document. This document is written for the Ventana Tegra development hardware and the
Android Gingerbread OS image
A picture of the supported Ventana touchscreen development kit hardware (with optional top-
mounted multi-camera module) is shown below:

Version <XXXXXXXX>: Platform Directory
In the usbpcdriver subdirectory of this platform directory.

Flash your OS:

2) Double click to run the flash .bat file, nvflash_1gb_lcd.bat. The flashing process
will begin immediately. At the end of a successful flash, remove the USB cable
connection to the PC. If you do not, Windows will ask for another driver, please cancel
a successful flash will look something like this:
sending file: bootloader.bin
\ 903580/903580 bytes sent
bootloader.bin sent successfully
sending file: boot.img
| 2529280/2529280 bytes sent
boot.img sent successfully
sending file: system.img
| 79590720/79590720 bytes sent
system.img sent successfully
Press enter to continue:
