The configuration problem of EPCS

Question

Hi,I am using cyclone 4 series for my design.I now use the JTAG and AS way to configure my FPGA.And I have a problem about the configuration of the FPGA.

Could I save two different configuration files in the flash memory of one single EPCS device which is connected to only one FPGA? And if that is possible,is there any way to let me to choose either one of the two different configuration files to config my FPGA?(EPCS device is connected to only one FPGA)

THANK YOU!

Yes, you can save two or more different configuration files in on single EPCS device. You need at least a Remote Update Controller (ALTREMOTE_UPDATE). Using the controller you can select an application image stored in the EPCS and initiate the configuration of FPGA. Please refer to "Configuration and Remote System Upgrades in Cyclone IV Devices" in Cyclone IV device handbook.

You have to take care of setting the MSEL Pins correct and you must change the configuration mode in Quartus to "Remote".
