  • Whole xpm->hsd→drp path is done except the JESD links.  Needs latest xpm/hsd/drp firmware.  New hsd firmware is 0x5000100. Feb. 6 hsd-drp firmware here https://github.com/slaclab/l2si-drp/releases (4.0.4) has this.  hsd needs new software since the address map changed (backwardly incompatible) but still in the eyediag branch only.  be careful when we merge this branch (do this in July downtime?)
  • JESD link eye-scan is in-progress (getting close)
    • JESD links are over the mezzanine connector (not firefly)
  • cmp005 datadev_1 eye-scan looks terrible (rix hsd_2, hsd_3, which are known bad).  lab3 hsd looks "poor" BER 10**-19, but expect 10**-21 in loopback mode.
    • Matt says two parameters in the MGT to try to improve lab3 loopback (exposed in pgp axilite interface): "diff control" "post cursor" (tx params).  matt exposed in epics.
    • not aware of any QSFP parameters (and we don't have I2C bus hooked up)
