Python

On Linux, installing Python & all the associated packages is much easier than on Windows. Typically you can install them from a package manager, if you are using Fedora Core or similar, just type:

$ sudo yum install python27 python27-devel python27-libs python-pyside numpy scipy python-configobj pyusb
$ sudo pip install pyqtgraph

On Ubuntu or similar:

$ sudo apt-get install python2.7 python2.7-dev python2.7-libs python-numpy python-scipy python-pyside python-configobj python-setuptools python-pip
$ sudo pip install pyusb
$ sudo pip install pyqtgraph

Getting the AVR Toolchain

Many of the tutorials use the AVR XMEGA microcontrollers as a target. In order to compile code for these targets, you'll need the AVR toolchain. This is easy to set up:

sudo apt-get install avr-libc gcc-avr

Hardware Drivers

The driver for Linux is built in, however you need to allow your user account to access the peripheral. To do so, you'll have to make a file called /etc/udev/rules.d/99-newae.rules . The contents of this file should be:

# CW-Lite
SUBSYSTEM=="usb", ATTRS{idVendor}=="2b3e", ATTRS{idProduct}=="ace2", MODE="0664", GROUP="plugdev"

# CW-1200
SUBSYSTEM=="usb", ATTRS{idVendor}=="2b3e", ATTRS{idProduct}=="ace3", MODE="0664", GROUP="plugdev"

# CW-305 (Artix Target)
SUBSYSTEM=="usb", ATTRS{idVendor}=="2b3e", ATTRS{idProduct}=="c305", MODE="0664", GROUP="plugdev"

# CW-CR2
SUBSYSTEM=="usb", ATTRS{idVendor}=="04b4", ATTRS{idProduct}=="8613", MODE="0664", GROUP="plugdev"
SUBSYSTEM=="usb", ATTRS{idVendor}=="221a", ATTRS{idProduct}=="0100", MODE="0664", GROUP="plugdev"

Then add your username to the plugdev group:

$ sudo usermod -a -G plugdev YOUR-USERNAME

And reset the udev system:

$ sudo udevadm control --reload-rules

Finally log out & in again for the group change to take effect.

You can always find the latest version of this file in GIT.

FTDI Hardware Driver (SASEBO-W, SAKURA-G, SASEBO-GII)

This is only required for supporting FTDI-connected hardware such as the SASEBO-W, SAKURA-G, SASEBO-GII. This is NOT required for the ChipWhisperer Capture Rev2.

First, you need to install the D2XX drivers & python module. See the section #Optional_Packages.

Currently, there is a bit of a hack needed. You have to create (or modify if it exists) the file /etc/udev/rules.d/99-libftdi.rules . The following modifications will cause any FTDI-serial device to stop working, so backup the existing file! The contents of this file should be:

SUBSYSTEM=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6010", MODE="0664", GROUP="plugdev"
ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6010", RUN+="/bin/sh -c 'echo $kernel > /sys/bus/usb/drivers/ftdi_sio/unbind'"

Then add your username to the plugdev group (if not already done):

$ sudo usermod -a -G plugdev YOUR-USERNAME

And reset the udev system:

$ sudo udevadm control --reload-rules

Finally log out & in again for the group change to take effect.
