Refresh a hardware device. Read device and core information from device.

Syntax

refresh_hw_device [‑update_hw_probes <arg>] [‑disable_done_check]
    [‑force_poll] [‑quiet] [‑verbose] [<hw_device>]

Usage

Name	Description
`[-update_hw_probes]`	Update hardware probe information, read from probes file
`[-disable_done_check]`	Disable done check for refresh device
`[-force_poll]`	Force poll of all targets
`[-quiet]`	Ignore command errors
`[-verbose]`	Suspend message limits during command execution
`[<hw_device>]`	hardware device Default: current hardware device

Description

Refreshes the in-memory view of the device by scanning for debug and IBERT cores on the specified hw_device object, and also reads a probe file when directed.

The Hardware Manager in the Vivado Design Suite creates, deletes, or updates the hw_ila, hw_vio, hw_sio*, and hw_axi objects based on the core information found in the device, and also what is read from the probes file in the case of ILA and VIO debug cores.

Use the refresh_hw_device after the program_hw_devices to keep the in-memory hardware debug objects in sync with the state of the actual cores on the physical device.

Arguments

-update_hw_probes <arg> - (Optional) Update the probes file (.ltx) associated with the specified device by reading the specified probes file.

Note: The probes file is associated with a hw_device object through the use of the set_property command to define the PROBES.FILE property.

-disable_done_check - (Optional) Disable the DONE check to enable the hardware manager to scan for debug cores on the current device, even if the DONE pin status is low. A High signal on the DONE pin indicates completion of the configuration sequence. The DONE check waits for the high state on the DONE pin to confirm configuration is complete.

-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_device> - (Optional) Specify the hw_device object to refresh. The hw_device must be specified as an object as returned by the get_hw_devices or the current_hw_device commands. If the hardware device is not specified, the current_hw_device will be returned.

Example

The following example refreshes the specified hw_device:

refresh_hw_device [lindex [get_hw_devices] 0]
