VPROG VPROG VNC1L Reflasher Application

The VPROG application can be used to reprogram the Flash memory of the VNC1L-1A and is available as a free download from the Vinculum web site. VPROG requires an FTDI 232 (USB-UART) device using the Windows CDM (D2XX) drivers. It is possible to use other devices with a UART, but these will require a different application which must be written by the developer.


To reprogram the VNC1L Flash memory, perform the following steps:

·	If required, use jumpers to enable the bootloader in the VNC1L device. See the hardware considerations section for more information on this.

·	Connect the FTDI 232-based reprogramming interface to the PC and install the CDM (D2XX) drivers.

·	Download VPROG from the Vinculum web site downloads page.

·	Download the required firmware from the Vinculum web site downloads page.

·	Run VPROG.exe.

   

·	Click on the drop down box and select the description of the FTDI 232 device being used to reprogram the Vinculum device.

   

·	Click the "ROM File..." button and browse to the ROM file to be programmed into the VNC1L.

   

·	Once a file is selected, the file path is displayed on the form. If a valid ROM file has been chosen and an FT232 has been selected, the device may be reprogrammed. Click "Program" to reprogram the VNC1L.

   

·	A progress bar indicates how much of the reprogramming process is complete.

   

·	A second progress bar is displayed while verifying the Flash memory.

   

·	A message box is displayed at the end indicating that the reprogramming has completed and was successful.
