- 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:
