1 Introduction
FTDI have introduced a new suite of simplified “bridging” ROM files to allow for fast interconnect
between differing interfaces. These ROM images (and sample code) are targeted at those users
who would like to implement VNC2 into a design without creating their own firmware.
To further simplify the use of this precompiled code, FTDI have also provided a new programming
utility called V2PROG which enables pre-compiled ROM files to be loaded into the VNC2 device over
the debugger/programmer interface without needing to use the IDE or FT_PROG. This may also be
of benefit in a mass production environment where the full IDE is not required.
1.1 Overview
VNC2 is the second of FTDI’s Vinculum family of embedded dual USB host controller devices. The
VNC2 device provides USB Host interfacing capability for a variety of different USB device classes
including support for BOMS (bulk only mass storage), Printer and HID (human interface devices).
For mass storage devices such as USB Flash drives, VNC2 transparently handles the FAT file
structure.
Communication with non USB devices, such as a low cost microcontroller, is accomplished via
UART, SPI or parallel FIFO interfaces. VNC2 provides a new, cost effective solution for providing
USB Host capability into products that previously did not have the hardware resources available.
VNC2 allows customers to develop their own firmware using the Vinculum-II software development
tool suite. These development tools provide compiler, assembler, linker and debugger tools
complete within an integrated development environment (IDE).
The Vinculum-II VNC2 family of devices are available in Pb-free (RoHS compliant) 32-lead LQFP,
32-lead QFN, 48-lead LQFP, 48-lead QFN, 64-Lead LQFP and 64-lead QFN packages For more
information on the ICs refer to http://www.ftdichip.com/Products/ICs/VNC2.htm.

Using a separate VNC2 Debugger/Programmer module requires interconnect as per figure 2.1.
Figure 2.2 Debugger/Programmer module
To allow for the VNC2 chip to be programmed it must be powered, The 5V supply from the
debugger module (if used) must be converted to 3V3/1V8 to supply the VNC2 chip via a regulator
on the VNC2 PCB. Alternatively a user may provide their own power supply.

3 Installing the Debugger/Programmer Module driver
To allow a PC to communicate with the debugger/programming module it is necessary to load a
driver for this module.
Installation of the Debugger/Programmer driver is a simple case of plugging the device in and
allowing the Windows Installation Wizard to go online, find and load the driver. For more details on
driver loading for different versions of Widows OS please refer to the Driver Installation Guides
Note: these drivers are also required by the V2PROG utility.

4 Installing V2PROG
V2PROG is downloadable from the FTDI website at
(http://www.ftdichip.com/Support/Utilities/V2PROG_Installer.zip)
The zip file should be downloaded and extracted onto the PC. This can be done with free utilities
such as Winzip by right clicking on the zip file and selecting “Extract files…” from the pop-up menu.
The extracted file V2PROG Installer.exe will now be placed in the folder of your choosing. Double
click on the file to run the exe and follow the on-screen prompts.

5 Running V2PROG
Double click on the V2PROG.exe file to open the application.
This should give a GUI with two boxes and a Program button.
The ROM path is the location that the Rom file is stored on the PC. In the figure below the file is
called FT232Uart.ROM and is located at C:\FTDI DATA.
The VNC2 device that was found is “VNC2 Debugger Module”. This is the default string returned
from the VNC2 debugger/programmer module. Simply ensure you select the device you want to
program.
Figure 5.1 V2Prog Screenshot
Press the Program button to load the file. The utility will show Status: Flash write done when it has
completed.
On completion of programming the device the utility will reset the VNC2 allowing for the
application ROM to start running.
