• kcuSim -t (resets timing counters)
• kcuSim -s (dumps stats)
• 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:

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