• 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.

Firmware

NOTE: Some KCU firmware (notably the hsd image named DrpPgpIlv) is reprogrammed over /dev/datadev_1.  Also, some images don't automatically detect the prom type.  A general KCU firmware reprogramming command would be:

python software/scripts/updatePcieFpga.py --path /reg/neh/home/cpo/junk --type SPIx8 --dev /dev/datadev_1

As of Jan. 20, 2021, Matt has firmware here:
