Hi munster-shug


For a software reset you could write to the register 0xFFD0500C.

You could trigger a cold or a warm reset with the register.

For a hardware reset you could toggle the "HPS_cold_resetn " and "HPS_WAM_RESETn".


I would suggest having a heartbeat system that could send some status signal back to your server to get a ping.

If the unit does not get a ping back the unit could reset through software.


One of the status that you could add in is the "stat register" of the HPS.

With this your server could get information if there is a reset happened in the unit.
