This repo is a WIP

This repository is a WIP and currently does not work. I would love contributions to make it work.

This repository aims to contains firmware for the Cypress FX2 which enables it to emulate much of the behaviour of the FTDI serial converter chips.

The primary purpose of this firmware is to enable the usage of the FX2 as a USB JTAG programmer with many popular existing tools.

The emulation has been created based on how two primary boards operate, both which have the FTDI FT2232H chip on them.

• Pipistrello
• TIAO USB Multi-Protocol Adapter (JTAG, SPI, I2C, Serial)

The secondary purpose is to allow easy interfacing to many common FPGA systems.

The firmware also aims to provide a common interface to both FX2 hardware and optimised bit banging routines.

The boards supported are;

• Digilent Atlys

• Numato Opsis

• TODO: More? Should be able to support everything in ixo-usb-jtag.

• TODO: Xilinx Platform Cable

The tools which have currently been tested are;

• TODO: xc3sprogs

• TODO: urjtag

• TODO: OpenOCD

• TODO: More? Should be able supported by everything that also supports the TIAO USB Multi-Protocol Adapter (JTAG, SPI, I2C, Serial)

Third Party

• libftdi.h comes from http://www.intra2net.com/en/developer/libftdi/
• ftdi_sio.h and ftdi_sio_ids.h comes from Linux Kernel
