# Beam Position Monitor Software Software for controlling the AFC BPM boards ## Prerequisites: Make sure you have the following libraries installed: * zeromq-4.0.4 (http://zeromq.org/area:download) * czmq-2.1.0 (http://czmq.zeromq.org/page:get-the-software) Cloning this repository git clone --recursive https://github.com/lerwys/bpm-software.git Install the Majordomo application from this repository (autotools-based) cd majordomo/libmdp Execute the traditional sequence of autotools commands: ./autogen.sh && make && sudo make install ## PCIe Installation Instructions 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: Testing OPEN DEVICE...

PASSED! ------------------------------------- | All tests PASSED! | ------------------------------------- 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. ## Installation Instructions Comple everything make Compile the examples make examples Run the server components with the helper script, like shown below: ./init.sh Typically, one should choose the IPC transport method for its faster than TCP. For instance: ./init.sh ipc:///tmp/bpm/0 Now we should be good to start making transactions. Change to the example applications folder cd examples Run the Example application ./client -v Leds should be blinking in the FMC ADC board
