GoodFET

The GoodFET is a nifty little tool for quickly exposing embedded system buses to userland Python code. It is no longer under active development, but I hope that you find it useful nonetheless.

If you are experimenting with the Facedancer USB emulator framework, you probably want Kate Temkin's fork. It is available at https://github.com/ktemkin/Facedancer .

Drivers

For Mac, install XCode, MacPorts, and the FTDI Virtual COM Driver.

For Windows, install Python 2.7 as 32-bit, FTDI VCP Drivers, and add Python your %PATH% in order to run the scripts in \client.

In Linux, the FTDI drivers are included by default. Be sure that the user has permissions for /dev/ttyUSB0, which will likely require adding that user to the dialout group.

Packages

You will need python-serial, wget, gcc-msp430, and curl. These might have different names, and the MSP430 compiler might be separated from its libc implementation.

sudo apt-get install -y gcc-msp430 msp430-libc curl wget python-serial # Ubuntu Xenial

Client

First, grab a copy of the client code and link it into /usr/local/bin.

git clone https://github.com/travisgoodspeed/goodfet/
(cd client && sudo make link)

Before using the client, you will need to specify your hardware revision in the $client or %client% environment variable.

Firmware

If your GoodFET has not yet been flashed, or if you would like to develop new firmware features, you will need to compile from scratch.

cd ~/goodfet/firmware
board=goodfet41 make clean all
