PRR

 

  • The follow-up went well. Green light for production
  • Alex will report about the PRR
  • Wait for technical board
  • The firmware was addressed in the PRR (mainly for the TPC cluster finder).
    • In September we have to produce a meeting in O2 plenary meeting to check for plan B is required or not
    • Final decision has to be done end of 2018.

 

Dwrapper

 

  • A bug was found in the PCIe and it was fixed (due to slow data rate)
  • Still something not understood, sometime data is not flowing (DMA not pushing data, reason yet unknown)
    • Many things were tried (fw reload, powercycling, ...). What did trigger the situation is not known
    • It happened right after doing the GBT slow control.
  • Datataking with two links, something was observed this morning, investigation under progress
  • Check GBT mode when using VLDB.
  • Firmware

 

CRU-tests

 

  • Tuan : pushed the changes, still has to test the change, probably on Thursday
  • Priority is now on the waveform player

 

Waveform player

 

  • It is still integrated in the dummy_user_logic
  • Tuan has some question about the dwrapper and the connection
  • Some test to be done.

 

Getting ready for release

 

  • validate DWRAPPER + documentation (see open topics above)
  • update WF_player + documentation
  • update cru-test repo to support the above + documentation
  • Integrate howTo (Oliver/PiPPo)
  • Validate all of these, please read the documentation, it will ease support later on!
  • merge in master
  • Tag fw and test tools
