VPROG VPROG VNC1L Reflasher Application
Return to Introduction  Previous page  Next page
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.
