I am planning to use Kintex-7 FPGA which will be connected to Parallel NOR flash in Master BPI mode for its configuration.
I want to know the possibility to keep more than 4 configuration files in the flash and configuration of FPGA from these files on selection basis.

1. Thank you for your reply, As i understood using RS0:1 lines we can select one file among 4 configuration files. I have requirement to store more than 4 configuration files, may be 5 or 6.
I want to know the feasibility for doing same.
2. Can SD card be used for configuration of Kintex-7 FPGA?

Please consider the Slave SelectMAP configuration interface that is shown by the figure below, which is from Xilinx document UG470.
Note that a microprocessor (eg. see www.microchip.com) is placed between the flash part and the FPGA. A simple 3-bit dip-switch can be connected to the microprocessor that indicates which of 8 configuration files are to be used. At power-up, the microprocessor reads the dip-switch setting, reads the dip-switch-specified configuration file from the flash part, and sends the configuration file to the FPGA. The FPGA acts as a slave device, simply waiting for the microprocessor to pass it a configuration file.
-of course, you will have to write some simple code that tells the microprocessor what to do.
