Vinculum II programming interface
« on: August 13, 2018, 01:34:02 PM »

Hi

I am currently using Vinculum VNC2 chip to make PC keyboard to command XMEGA controller. With sample code "USB HID to SPI Master Sample Application ROM" it is working very well. But there has been a problem that Vinculum does forget it's firmware sometimes (luckily very rarely).

It would be great to use XMEGA to re-program the chip if the problem persists on field and user has no separate programmer device. I just cant find any documentation how to interface the chip to program it.

Regards,
Hihilintu!

Hello,

I believe you also contacted email support with the same issue. Please continue to correspond via that support channel and we will post the resolution here.

Hi,

My colleague contacted the FTDI support via email. We are working on the same project.

We would like to program the VNC2 flash using an MCU which is on the same PCB. End users do not have the VNC2 debug module.
What we would like to know is how to make the connection between the MCU and VNC2 and see example code how to program the flash.

Some of our customers have had problems when the VNC2 has "lost" its firmware and they had to send us the PCB for reprogramming. It would be very beneficial for all of us if the MCU could reprogram the VNC2 flash.

In short, we would like to use our MCU as the VNC2 debug module.
