Cloning this repository

Installation Instructions

Server

To install the server-side you'll need libsodium, zeromq, czmq and mlm. Check the documentation or the previous section for details.

Currently we support 2 build systems: Make and CMake. The recommended approach is to use CMake.

CMake

To use CMake do the following steps:

mkdir -p build
cd build
cmake ../
make
sudo make install

HALCS CMake scripts also supports CPack. So you can easilly generated .deb or .rpm packages for your distribution with:

For Debian-based distros:

mkdir -p build
cd build
cmake ../
cpack -G "DEB"

For Redhat-based distros:

mkdir -p build
cd build
cmake ../
cpack -G "RPM"

Make

To use Make do the following steps:

make
sudo make install

Alternatively, you can use the compile.sh script that wraps the make options into command-line options:

./compile.sh [-b <board>] [-a <applications>] [-e <with examples = yes/no>] \
    [-l <with library linking = yes/no>] [-d <with driver = yes/no>] [-x <extra flags>]

Client

To install the server-side you'll need libsodium, zeromq and czmq. Check the documentation or the previous section for details.

CMake

To use CMake do the following steps:

TOP=$(pwd)
for lib in \
    errhand \
    convc \
    hutils \
    disptable \
    llio \
    halcsclient \
    acqclient \
    bpmclient \
    sdbfs \
    sdbutils; do

    (
        cd ${TOP}/libs/${lib} && \
        mkdir -p build && \
        cd build && \
        cmake ../ && \
        make && \
        sudo make install
    )
done

If you need to uninstall the libraries do:

TOP=$(pwd)
for lib in \
    sdbutils \
    sdbfs \
    bpmclient \
    acqclient \
    halcsclient \
    llio \
    disptable \
    hutils \
    convc \
    errhand; do

    (
        cd ${TOP}/libs/${lib} && \
        mkdir -p build && \
        cd build && \
        cmake ../ && \
        sudo make uninstall
    )
done

Make

To use Make do the following steps:

Install the inner dependencies:

make deps
sudo make deps_install

And, then the client libraries themselves:

make libs
sudo make libs_install

If you need to uninstall the libraries do:

sudo make libs_uninstall

Examples

Compilation Instructions

Change to the examples folder

cd examples

CMake

Compile the examples using CMake (recommended):

mkdir -p build
cd build
cmake ../
make

Make

if needed, compile the examples with Make:

make

Running the examples

Run an example application, for instance, the leds example

./leds -v -b <broker_endpoint> -board <board_number> -halcs <halcs_number>

Typically, one should choose the IPC transport method for its faster than TCP. For instance:

./leds -v -b ipc:///tmp/halcs -board <board_number> -halcs <halcs_number>

If one would like to use TCP, it should call, for instance:

./leds -v -b tcp://127.0.0.1:8888 -board <board_number> -halcs <halcs_number>

Leds should be blinking in the FMC ADC board

Additional PCIe driver instructions

Installation instructions (if not installed with the main application)

Install linux header files

sudo apt-get install linux-headers-generic

Install the GIT package

sudo apt-get install binutils gcc

Change folder to the pcie driver location

cd kernel

Compile the PCIe driver and its tests

make

Install the PCIe drivers and libraries

sudo make install

Load the Driver module

sudo insmod /lib/modules/$(uname -r)/extra/PciDriver.ko

After this the kernel should have found the FPGA board and initialized it. Run the following command and check its output

dmesg | tail

You should see something like the excerpt below:

[267002.495109] pciDriver - pcidriver_init :
	Major 250 allocated to nodename 'fpga'
[267002.495130] pciDriver - pcidriver_probe :
	Found ML605 board at 0000:01:00.0
[267002.495224] pciDriver - pcidriver_probe :
	Device /dev/fpga0 added
[267002.495434] pciDriver - pcidriver_probe_irq :
	Registered Interrupt Handler at pin 1, line 11, IRQ 16
[267002.495450] pciDriver - pcidriver_init :
	Module loaded

Running the PCIe self-test

After the installation of the PCIe driver (see above) it is possible to run a self test to check if everything is setup properly. For this run the following:

Change to the "compiled tests folder"

cd tests/pcie/bin

Run the test entitled "testPciDriverMod"

sudo ./testPciDriverMod

You should get an output like the following, if everythig is ok:

Notice that some tests that try to evaluate the limits of a current Linux Kernel may fail in some cases. In the example above, two tests , due to an attempt to allocate a large buffer in kernel space.

This is not actually an error or a failure, it is just trying to allocate more memory than the kernel has available.
