Syntax

refresh_hw_axi [‑quiet] [‑verbose] [<hw_axis>...]

Usage

Name	Description
`[-quiet]`	Ignore command errors
`[-verbose]`	Suspend message limits during command execution
`[<hw_axis>]`	List of hardware AXI objects.

Description

Refresh the STATUS properties of the hw_axi object with the values from the current hw_device.

The refresh command takes the values from the status registers of the JTAG to AXI MASTER on the hardware device, and populates them into the appropriate properties of the hw_axi object in the hardware manager.

Refresh the STATUS properties of the specified hw_axi objects. THE STATUS properties include: STATUS.AXI_READ_BUSY, STATUS.AXI_READ_DONE, STATUS.AXI_WRITE_BUSY, STATUS.AXI_WRITE_DONE, STATUS.BRESP, and STATUS.RRESP.

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

Arguments

-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_axis> - (Required) The hw_axi objects to refresh. The hw_axi must be specified as an object returned by the get_hw_axis command.

Example

The following example refreshes the STATUS properties of the hw_axi objects:
