Hello,

Which VNC2-48 Development Module and USB to UART bridge are you using exactly?

Please see AN_159 Vinculum-II Firmware Flash Programming which should help you.

Note that when programming VNC2 via UART, to enable bootloader mode, the PROG# pin must be driven low and VNC2 must
then be reset by driving the RESET# pin low then high.

I have tested this here and it works as expected:

Hello

I am looking for solutions to the problem of non-programming VNC2 chip(I am use VNC2-48 Development Module). When I was in
FLASH ROM window, I choose Chip to VNC2, Programming Interface to UART and Com Port to COM4 and I choose Baud rate to the lowest number 115200. I choose this because I use my own usb to uart bridge support to 1Mb baudrate, I don't use TTL-232R-3V3 Cable . When I Click on program,  status bellow image of folder write that  device is correct and after this FT_Prog try to set baud rate and after this ouer program FT_Prog freezes and finnalny I don't lode rom file to my developer board.


Please Help me!!!!!!!!!!!!
