Useful commands from Ric for looking at the history of DAQ Prometheus data:

Timing System kcu1500 (or "sim")

• When only one datadev device is found in /dev or /proc when two are expected, the BIOS PCIe bifurcation parameter may need to be changed from "auto" or "x16" to "x8x8" for the NUMA node (slot) containing the PCIe bus holding the KCU card
  • If the BIOS PCIe bifurcation parameter seems to be missing (was the case for the SRCF DRP machines), the BIOS version may be out of date and need updating
• kcuSim -t (resets timing counters)
• kcuSim -s (dumps stats)
• kcuSim -c (setup clock synthesizers)
• Watch for these errors: RxDecErrs 0 RxDspErrs 0
• reload the driver with "systemctl restart tdetsim"
• currently driver is in /usr/local/sbin/datadev.ko, should be in /lib/modules/<kernel>/extra/
• reloading the driver does a soft-reset of the KCU (resetting buffer pointers etc.).
• if the soft-reset doesn't work, power-cycle is the hard-reset.
• program with this command:  "python software/scripts/updatePcieFpga.py --path ~weaver/mcs/ --dev /dev/datadev_1" (datadev_1 if we're overwriting a TDET kcu, or could be a datadev_0 if we're overwriting another firmware image)

• to see the optical powers Matt says we should run the software in psdaq/psdaq/pykcu:
  

  Code Block

  drp-neh-cmp001:~$ pykcu -d /dev/datadev_1 -P DAQ:NEH & Rogue/pyrogue version v5.9.3. https://github.com/slaclab/rogue Start: Started zmqServer on ports 9103-9105 ClkRates: (185.987104, 185.974688) RTT: ((0, 0), (0, 0), (0, 0), (0, 0)) drp-neh-cmp001:~$ pvget DAQ:NEH:DRP_NEH_CMP001:MON DAQ:NEH:DRP_NEH_CMP001:MON 2021-12-03 18:46:38.708 RxPwr TxBiasI FullTT nFullTT 3.7888 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 drp-neh-cmp001:~$

  
  

• this is the correct firmware to program into the kcu:

  drp-neh-cmp001:~$ ls -rtl ~weaver/mcs/*TDet*2020* -rw-r--r-- 1 weaver ec 31345008 Jun 12 2020 /cds/home/w/weaver/mcs/DrpTDet-20200612_primary.mcs -rw-r--r-- 1 weaver ec 31345008 Jun 12 2020 /cds/home/w/weaver/mcs/DrpTDet-20200612_secondary.mcs drp-neh-cmp001:~$
