Installing OpenOCD
..................
There are several tools that can be used to write the thee binaries into the core device FPGA board's flash memory.
Xilinx ISE (impact) or Vivado work, as does xc3sprog sometimes.
OpenOCD is the recommended and most reliable method.
It is however not currently packaged as a conda package nor has it been tested on Windows.
OpenOCD can be used to write the binary images into the core device FPGA board's flash memory. It can be installed using conda on both Linux and Windows::
Use these commands to download, build, and install ``openocd`` from source on Debian or Ubuntu systems::
$ conda install openocd
$ cd ~/artiq-dev
$ git clone https://github.com/ntfreak/openocd.git
$ cd openocd
$ sudo apt-get install build-essential libtool libusb-1.0-0-dev libftdi-dev automake
$ ./bootstrap
$ ./configure
$ make
$ sudo make install
$ sudo cp contrib/99-openocd.rules /etc/udev/rules.d
$ sudo adduser $USER plugdev
Some additional steps are necessary to ensure that OpenOCD can communicate with the FPGA board.
On Linux, first ensure that the current user belongs to the ``plugdev`` group. If it does not, run ``sudo adduser $USER plugdev`` and relogin. Afterwards::
$ wget https://raw.githubusercontent.com/ntfreak/openocd/406f4d1c68330e3bf8d9db4e402fd8802a5c79e2/contrib/99-openocd.rules
$ sudo cp 99-openocd.rules /etc/udev/rules.d
$ sudo adduser $USER plugdev
$ sudo udevadm trigger
On Windows, a third-party tool, `Zadig <http://zadig.akeo.ie/>`_, is necessary. Use it as follows:
1. Make sure the FPGA board's JTAG USB port is connected to your computer.
2. Activate Options → List All Devices.
3. Select the "Digilent Adept USB Device (Interface 0)" (for KC705) or "Pipistrello LX45" (for Pipistrello) device from the drop-down list.
4. Select WinUSB from the spinner list.
5. Click "Install Driver" or "Replace Driver".
You may need to repeat these steps every time you plug the FPGA board into a port where it has not been plugged into previously on the same system.
Then, you can flash the board:
