XPM Timing Links Not Locking

If XPM links don't lock, here are some past causes:

• check that transceivers (especially QSFP, which can be difficult) are fully plugged in.
• for opal detectors:
  • use devGui to toggle between LCLS1/LCLS2 timing (Matt has added this to the opal config script, but to the part that executes at startup time)
  • hit TxPhyReset in the devGui (this should now be done in the opal drp executable)
• for timing system detectors: run "kcuSim -s -d /dev/datadev_1", this should also be done when one runs a drp process on the drp node (to initialize the timing registers).  the drp executable in this case doesn't need any transitions.
• hit Tx/Rx reset on xpmpva gui (AMC tabs).
• Valerio and Matt had noticed that the BOS sometimes lets its connections deteriorate. To fix:
  • ssh root@osw-daq-calients320
  • omm-ctrl --reset
