Refresh the status of the current hardware object. Inputs can be hw_server, hw_target, hw_device or hw_sysmon objects. At least one object is required. If properties are specified that do not exist in the object, that property will not be refreshed.


refresh_hw_sysmon [‑regexp] [‑properties <args>] [‑quiet] [‑verbose]


Name Description
[-regexp] Properties list contains full regular expressions
[-properties] List of properties to refresh Default: All properties in object
[-quiet] Ignore command errors
[-verbose] Suspend message limits during command execution
<hw_objects> hardware objects




Refresh the properties of the hw_sysmon object with the values on the system monitor (XADC) from the current hw_device.

The refresh command takes the values from the status registers of the system monitor on the hardware device, and populates them into the appropriate properties of the hw_sysmon object in the hardware manager.
Tip: The hw_sysmon object is automatically refreshed at the rate specified by the SYSMON_REFRESH_RATE_MS on the object.

This command updates the properties on the hw_sysmon object, but otherwise returns nothing if successful. The command returns an error if it fails.


-regexp - (Optional) The list of properties to refresh is defined using regular expression.

-properties <args> - (Optional) Refresh the specified property or properties of the hw_sysmon object. As a default behavior, if no properties are specified, all properties of the specified object or objects will be refreshed from the current values on the hardware device.
Tip: If a non-existent property is specified, that property is ignored.
-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
Note: Message limits can be defined with the set_msg_config command.
<hw_objects> - (Optional) Specify the system monitor to refresh the properties of, with values from the hw_device. The system monitor object can be specified as the hw_sysmon object, or as the system monitor through the associated hw_device, hw_target, or hw_server objects.
Note: The objects must be specified using the appropriate get_hw_xxx command, for instance get_hw_sysmon, rather than specified by name.


The following example refreshes the TEMPERATURE property of the hardware system monitor object with the actual temperature on the current device:
refresh_hw_sysmon -properties {TEMPERATURE} [lindex [get_hw_sysmons] 0]
