15 years agoThe configuration problem of EPCS
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!2 Replies

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.
