Questions about the flashing using SPI Loader

I recently brought the Nitefury II board and I'm looking forward to using it. Currently it has the factory default bitstream. I installed the xdma kernel module, the board is detected and I was able to run the example to identify the board.

I currently don't have a JTAG, and it won't be arriving for about a week or so. Meanwhile I wanted to know if I can use the spi-loader on the factory default bitstream. When I run the spi-loader test it freezes after Initializing flash index 0. Any idea why this is happening?

$ ./spi-loader -a 0x240000 -f ./64KiB.bin 
Loading 65536 bytes from ./64KiB.bin[0] to flash[2359296] using /dev/xdma0_user[65536]

Initializing flash index 0...

Other questions about the flashing over PCIe using the spi-loader:

Which address should I write a new bitstream into?
Will I have to overwrite the existing bitstream everytime?
