Connectal provides a hardware-software interface for applications split between user mode code and custom hardware in an FPGA. Portal can automatically build the software and hardware glue for a message based interface and also provides for configuring and using shared memory between applications and hardware. Communications between hardware and software are provided by a bidirectional flow of events and regions of memory shared between hardware and software. Events from software to hardware are called requests and events from hardware to software are called indications, but in fact they are symmetric.
A logical request/indication pair is referred to as a portal". An
application can make use of multiple portals, which may be specified
independently. A portal is specified by a BSV interface declaration,
connectalgen generates BSV and C++ wrappers and
Connectal has a mailing list: https://groups.google.com/forum/#!forum/connectal
See the documentation for more details: http://www.connectal.org/doc/current/ref/
Connectal supports Android on Zynq platforms, including zedboard and zc702.
Connectal supports Linux on x86 with PCIe-attached Virtex and Kintex boards (vc707, kc705).
Connectal supports bluesim as a simulated hardware platform.
- Install the Bluespec compiler. Connectal is known to work with 2014.07.A and 2015.05.beta1
Install the bluespec compiler. Make sure the BLUESPECDIR environment variable is set appropriately:
Install Vivado 2015.2 or 2015.4
sudo add-apt-repository -y ppa:jamey-hicks/connectal sudo apt-get update sudo apt-get -y install connectal
Building from Source
Checkout out the following from github:
git clone git://github.com/cambridgehackers/connectal
If you are generating code for an FPGA, check out fpgamake:
git clone git://github.com/cambridgehackers/fpgamake
It appears that this requires buildcache to be checked out also:
git clone git://github.com/cambridgehackers/buildcache
USE_BUILDCACHE=1to your calls to make to enable it to cache, otherwise it will rerun all compilation steps.
Install connectal dependences. This installs ubuntu packages used by connectal or during compilation:
cd connectal; sudo make install-dependences
If you are using an FPGA attached to your machine, install the drivers:
make all sudo make install
Preparation for Zynq
Download the Android Native Development Kit (NDK) from: http://developer.android.com/tools/sdk/ndk/index.html (actual file might be: http://dl.google.com/android/ndk/android-ndk-r10e-linux-x86_64.tar.bz2 )
Connectal uses NDK to compile code to run on Zynq platforms.
Add the NDK to your PATH.
URL=http://dl.google.com/android/ndk/android-ndk-r10e-linux-x86_64.tar.bz2 curl -O `basename $URL` $URL tar -jxvf `basename $URL` PATH=$PATH:/scratch/android-ndk-r10e/
Download and install ADB from the Android Development Tools.
The Android Debug Bridge (adb) is packaged in platform-tools. Connectal uses adb to transfer files to and from the Zedboard over ethernet and to run commands on the Zedboard.
User your browser to accept the conditions and download the SDK installation tarball:
Unpack the installation tarball:
tar -zxvf android-sdk_r22.6.2-linux.tgz
androidtool to install SDK components
Add adb to your path:
Create/obtain a boot.bin and SD card image for your board
Follow the instructions at https://github.com/cambridgehackers/zynq-boot
Copy the files to the SD card, eject the card from the PC, and plug it into the zedboard/zc702/zc706 and boot.
Preparation for Kintex and Virtex boards
Install the drivers
make sudo make install sudo modprobe portalmem
git clone git://github.com/cambridgehackers/fpgajtag cd fpgajtag make all && sudo make install
Generally cd to the project directory, then type
cd examples/examplename make build.<target> make run.<target>
where target is
|bluesim||compile for simulation|
|zedboard||compile for zedboard|
|zybo||compile for zybo|
|zc702||compile for zc702 board|
|zc706||compile for zc706 board|
|kc705||compile for kc705 board|
|vc707||compile for vc707 board|
|vc709||compile for vc709 board|
|nfsume||compile for NetFPGA-SUME board|
To turn on more verbosity for debugging when running make, add V=1 to command line, as
make examples/examplename.<something> V=1
V=1 make examples/examplename.<something>
To run the example on a machine different than the build machine, use RUNPARAM=hostname-or-addr:
make RUNPARAM=zedtest run.zedboard make RUNPARAM=192.168.1.123 run.vc707
The FPGA bitstream is included in the application executable, and the FPGA is automatically programmed when the application is run:
cd examples/echo make build.vc707 ./vc707/bin/ubuntu.exe
We are running Android on the Zynq devices and so the application executable is called android.exe.
## this has only been tested with the Vivado 2013.2 release . Xilinx/Vivado/2013.2/settings64.sh make -C examples/echo build..zedboard
make -C examples/echo build.zc702
make -C examples/echo build.kc705
make -C examples/echo build.vc707
To run on a zedboard with IP address aa.bb.cc.dd:
RUNPARAM=aa.bb.cc.dd make -C examples/echo run.zedboard
make -C examples/memcpy build.vc707
