Build FPGALink and the cksum VHDL example, and use flcli to write data to an LX9R3 board, and then read data back from it.

Building FPGALink & the cksum example VHDL for MakeStuff LX9R3 on Linux:

# Install prerequisites:
sudo apt-get install build-essential libreadline-dev libusb-1.0-0-dev python-yaml
mkdir $HOME/20140524
cd $HOME/20140524
wget -qO- http://tiny.cc/msbil | tar zxf -

# Fetch and build flcli:
cd makestuff/apps
../scripts/msget.sh makestuff/flcli/20140524
cd flcli
make deps
cd ../../

# Fetch and build the VHDL version of the cksum example:
scripts/msget.sh makestuff/hdlmake
cd hdlmake/apps
../bin/hdlmake.py -g makestuff/swled
cd makestuff/swled/cksum/vhdl
../../../../../bin/hdlmake.py -t ../../templates/fx2min/vhdl -b lx9r2 -p fpga

# Load FPGALink firmware into the LX9R3:
../../../../../../apps/flcli/lin.x64/rel/flcli -v 1d50:602b:0002 -i 04B4:8613

# Program the FPGA:
../../../../../../apps/flcli/lin.x64/rel/flcli -v 1d50:602b:0002 -p J:A7A0A3A1:fpga.xsvf

# Write 64KiB of random data to the board:
dd if=/dev/urandom of=random.dat bs=1024 count=64
../../../../../../apps/flcli/lin.x64/rel/flcli -v 1d50:602b:0002 -a 'w0 "random.dat";r1;r2' -b

# And now read 64KiB (0x10000 bytes) back from the board and save it as "out.dat":
../../../../../../apps/flcli/lin.x64/rel/flcli -v 1d50:602b:0002 -a 'r0 10000 "out.dat"'

Alternatively, on Windows:

1) Install the Windows SDK:
     http://download.microsoft.com/download/A/6/A/A6AC035D-DA3F-4F0C-ADA4-37C8E5D34E3D/winsdk_web.exe

2) For x86, install this (choose "install just for me"):
     http://www.python.org/ftp/python/2.7.6/python-2.7.6.msi

   Alternatively for x64, install this (choose "install just for me"):
     http://www.python.org/ftp/python/2.7.6/python-2.7.6.amd64.msi

3) Install:
     http://pyyaml.org/download/pyyaml/PyYAML-3.10.win32-py2.7.exe

4) Download this and uncompress it to C:\makestuff:
     http://tiny.cc/msbiw

5) Run C:\makestuff\setup.exe, select the C/C++ compiler, Xilinx ISE and Python 2.7 and click
   "Create Shortcut".

6) Launch the new desktop shortcut & continue at the shell-prompt (hint: you can paste into the
   console window using the right mouse button).

# Connect the LX9R3 & use Zadig to install a new WinUSB driver for 04B4:8613:
zadig.sh

# Fetch and build flcli:
cd $HOME/apps
msget.sh makestuff/flcli/20140524
cd flcli
make deps
cd ../../

# Fetch and build the VHDL version of the cksum example:
