B33 Integration FELIX Setup


B84 FELIX Test Setup 



FELIX Configuration Process

  1. Assemble the test stand according to figures from the "B84 FELIX Test Setup" section. Plug in MTP12-CH1-TXA1 cable (labeled as "1") into the VLDB's RX.
  2. Configure VLDB (this part to be updated).
  3. Update/install the most recent Felix firmware (assuming Vivado Lab is installed, and one has access to GUI):

    1. Plug in a JTAG-USB cable in a correct port on the FLX-712 board.

      Xilinx Dongle:

      No LED light: PC doesn't see the dongle. Check drivers.

      Yellow LED: No target. Check JTAG connections.

      Green LED: Good! Can Proceed.

    2. Get the .bit file from a CERN webpage or directly upload v4.9.
    3. In Vivado Lab detect the target, use the .bit file to configure.
    4. Reboot the PC.
    5. Unplug the MTP12-CH1-TXA cable from the VLDB, make sure you observe red light coming from the wire, plug it back to the VLDB's RX. You can use TXA ch1 through ch4 cables.
    6. If there is no GUI and/or Vivado on the Felix server, one may use an external PC to configure the FLX-712 board: keep the board in the server, plug the Xilinx USB dongle into the external PC and run Vivado from there.
    7. Now you should see the RXDATA LED lighting with dim red color.




  4. Configure VLDB (GUI is needed for java):
    1. Supply 5V with 1A limit in current to VLDB. With 5V input voltage a VLDB may consume as low as 300mA. Once the VLDB and Felix configuration process is done, the board consumes about 450mA.
    2. Use the .jar programmer file and the txt config file.
    3. Run:
      $ java -jar programmerv2.20180725.jar
      Java GUI will appear.
    4. Click "import i..." in the top left corner and select the txt config file.
    5. Click "Write GBTX". After the process is done, GUI should look like the attached screenshot




  5. Set up FELIX:
    1. Run (from /home/itpix/FELIX/felix-04-01-00-stand-alone/x86_64-centos7-gcc8-opt/bin/ in the particular SLAC server):
      $ ./flx-init -c0 
      Run the init comment only one. If you run it twice or more, you need to reboot the computer.
      $ ./flx-info -c0
      May omit the info command, but it is useful to crocs-check that everything is ok.
    2. Check polarity of the channels, and invert if needed:
      $ ./flx-config -d0 list | grep polarity
      $ ./flx-config -d1 list | grep polarity
      If you observe something like "      GBT-TXPOLARITY 0x000000000000", run:
      $ ./flx-config -d1 set GBT-TXPOLARITY=0xffffffffffffffff 
      -d1 option selects the 1st FLX card. 
    3. If everything was done properly, the other two LEDs - TXRDY and RXRDY - should light up:


  • No labels
