Question about remote update controler on stratix2

There will not be any pin generated as remote update block. You can look at Application Selector reference designs of NEEK. This is used to initiate fpga configuration from pre-loaded location, it could be either parallel flash or epcs.

Remote Update can be used on the Stratix using a NIOS II processor or some custom-designed logic block for the interface. The altremote_update interfaces to the logic/nios not to external pins.

Thank you for Ketan and Mickey!!!!You mean that I can use the Remote Update Controller(Cyclone3) component which works well in stratix2 and I can direct use the component because it contains both the interface and altremote_upgrade megafunction.Is it true that when I give the command that setting the reconig to '1' to the component and the remote upgrade circuits works?

I guess you will find sufficient information in user guide as mentioned by Mickey and also you can use c source of application selector utility to have more idea.

Thank you very much!!!

NEEK is Nios II Embedded Evaluation Kit, You can find package of NEEK from altera website which contains reference design in example folder and also there is a example on how to use remote update utility as they are using this utility in application called application selector.

Thank you i have download that and the example shows that using the remote update controller does not need to write the sw_tcl file. Only the hw_tcl file is enough.Am i right?If it is true,how to controll the reconfiguration by nios2 core without the sw_tcl file?

You need to have hw_tcl and optionally sw_tcl when you design any SOPC compliant component. I don't think you need anything to write as long as your intention is to use altera's remote update component.
