Connectal PCIe: Getting Started
Use the PCIe bus to connect an FPGA Board to an X86 host machine running Linux. Build and execute a Connectal project. This tutorial includes instructions on how to install the entire tool-chain locally. If you can't/don't want to do this, use the Connectal Build service as shown in the zedboard example.
Parts List
0. Build/Host machine running Ubuntu
1. Xilinx VC707 or KC705 Board
2. Power cable for FPGA board
3. USB to Micro-USB cable
4. 8-lane PCIE ribbon cable (optional)
Connect the Board to the Host Machine
If the form factor permits, plug the board directly into an open PCIE slot on the motherboard of your host machine. In these instructions we are using a 1u rack-mounted server, which requires the use of a PCIe ribbon cable.
Connect the Programming Cable
Connect the MICRO USB end of the cable to the Digilent USB JTAG surface-mounted programming module and the other end to a vacant USB port on the host machine
Connect the Power Cable
Connect the power cable to the board and plug the other end into a wall socket. Power on the host machine and the FPGA board.
Install Vivado
Skip this step If you are using the Connectal Build service.
Connectal currently supports version 2014.1
Install Bluespec
Skip this step If you are using the Connectal Build Service.
On some machines, the underlying Haskell runtime requires a specific version of libgmp. This dependency appears to be artificial and can easily be faked with the following command:
sudo ln -s /usr/lib/x86_64-linux-gnu/libgmp.so.10.1.3 /usr/lib/x86_64-linux-gnu/libgmp.so.3
Install Connectal
Even if you are using the Connectal Build Service, you must install the packages to program the device and execute your design. The following commands add the connectal repository and download/install the packages:
sudo apt-add-repository -y ppa:jamey-hicks/connectal sudo apt-get update sudo apt-get install connectal<br>
You will need to reboot the machine (for udev). If the portalmem driver is not loaded automatically, load it using modprobe
sudo modprobe portalmem
The installation script writes the Connectal source to /usr/share/connectal.
Compile and Run a Design
If you are using the Connectal Build Service, follow the examples here to build the design (be sure to use https://github.com/connectal-examples/simple.git and to select the right build target). Otherwise, continue with this step to download and compile the design locally.
Check out an example project and compile build it for the board you have installed (kc705)
git clone https://github.com/connectal-examples/simple.git cd simple make CONNECTALDIR=/usr/share/connectal IPDIR=~/connectalip build.kc705
finally, run the example:
make CONNECTALDIR=/usr/share/connectal IPDIR=~/connectalip run.kc705
If this your first attempt after installing the board, the run command will fail with the following error (or similar):
Failed to open /dev/portal1 fd=-1 errno=2
If this is the case, reboot your host machine a second time (for BIOS PCIe detection) and re-invoke the run command:
mdk@xg06:~/sandbox/simple$ make CONNECTALDIR=/usr/share/connectal IPDIR=~/connectalip run.kc705
make -C kc705 BOARD=kc705 --no-print-directory run
