• ePix Notes (Dan's) 

STEP 1 (only good if you know the firmware and can program over fiber)

• Skip to step 10: Assuming optical cable is plugged in correctly

  • At command prompt: 

    $ cat /proc/pgpcard_0

  • Scroll up to Lane 0: Should see:

    LockLinkReady	1
    RemLinkReady	1

    • Power cycle, but if tries of theat does not work...
    • Lane 0 is hard coded into firmware: Move the optical quad connection in back of the computer & try again
• Where is firmware located?
  • EPIX Repo --> ~/IC_projects/epix/firmware/targets/Epix10ka/images
  • (FIRST TIME ONLY) CLONE: Have to clone the repo first...
    • If already done, skip to "Check out branch"
    • https://github.com/slaclab/epix
    • 
• CHECK OUT BRANCH: that is "actively" being updated
  • Checking out branch

    $ cd IC_projects/epix
    # where I have my local git repo
    $ git checkout rogue_v5.14
    $ git branch
    # make sure you see that you're in branch rogue_v5.14
    $ git pull
    # make sure "Already up to date."

  •  If having trouble with $ git pull...

    # note the $ is command line prompt
    $ cd IC_projects/epix
    $ git fetch
    $ git submodule update --force

  • 

• Repo is setup, rogue version is specified, have script for programing over fiber
  • Checking if MCS file is there
    • $ cd firmware/targets/Epix10ka/images/
  • Load the MCS file, but make sure number is same as firmware: See ePix Notes (Dan's) 
    • 
    •  (FIRST TIME ONLY) UNZIP:

      UNZIP: Another first time step... need to unzip

      

      hold

      # Will remove source files, but don't worry they are version controlled 
      $ gunzip *

    • Actually loading the MCS file...
      • Loading MCS

        $ cd ~/IC_projects/epix/software/Epix/
        $ source setup_template.sh
        $ cd scripts/
        $ python epixGen2LoadFpga.py --mcs=../../../firmware/targets/Epix10ka/images/Epix10ka-0xE2040002-20210715112919-mkwiatko-328bae7.mcs
        # Don't worry about warnings, if you get an error, find a firmware engineer to help

      • If written correctly
        • ignore errors after this...

STEP 2: Check if Firmware has been loaded correctly

• $ python epix10kaDAQ.py
• 
• GitHashShort is more important
