Hi, 

I used the quartus ii 11.1 to generate the .sof file, and downloaded to the cyclone ii. The tool Programer show "successfully". But when i tried to download nios to fpga flash in nios ii eclipse, the flash programer show error that timestamp mismatched. I checked the connected time number , and found it was the last project's time number. So I concluded that the current sof file did not been downloaded to the fpga. 

I am quiet cofused now, why does this situnation occurs? and how can i figure it out?

Hello 867, 

Everytime you generate the qsys file, the SOPC file has a time linked to the SOF. If you program the SOF to the fpga, and somehow regenerate the same qsys file again. They will not have the same timestamp. If you know they are the same, you can ignore the timestamp when using eclipse.
