TinyXVC - minimalistic XVC (Xilinx Virtual Cable) server

Introduction

This program is an implementation of XVC protocol, that allows user to connect their custom hardware to the development tools via "virtual cable".

Currently txvc supports only one type of backend - FT2232H chip, that acts as intermediate between PC and JTAG TAP.

Users are encouraged to add their own backend implementations.

How to use

Currently txvc supports only Linux hosts. To install needed tools and dependencies run:

$ sudo apt install build-essential
$ sudo apt install cmake
$ sudo apt install libftdi1-dev

Once sources are checked out it can be built with:

$ cd TinyXVC
$ mkdir build && cd $_
$ cmake ../
$ make all

To run txvc you need to provide a "profile" to initialize backend appropriately for interacting with your hardware. E.g.:

$ ./txvc -p mimas_a7

To get info about profiles and other options:

$ ./txvc -h

Troubleshooting

If you're experiencing failures from ftdi_usb_open():

• ensure that kernel ftdi_sio module is unloaded:

  $ sudo modprobe -r ftdi_sio
  

• install appropriate udev rules by following instructions from udev/ and restart PC
