The Cyclone V SoC chips are configured by default from the same SD card or serial flash that holds the Linux kernel and file system image. There is no need for a separate configuration chip unless you want it to boot a few seconds faster. If you do decide to use a separate configuration chip, you will need the bigger one. Note that some (but not all) non Altera serial flash chips can also be used to hold Cyclone V configuration images.

Thanks, its what i realized yesterday, after work, that i could just let linux boot it. This poppout another question ; What would be the cheapest way to boot the board (linux side) Should i use SD card? Can this flash be used to hold linux and the bitstream? (http://www.digikey.com/product-search/en?lang=en&site=us&wt.z_cid=ref_findchips_standard&mpart=ksz9021gq). It is the chip used on a digilent board with a zynq.

What is the expected size for a linux distro with gcc + network stack?

My current application is to acquire many LVDS channel, transfer the data to HPS, and from there, use the easy to use Linux network stack to send data trough either UDP or TCP/IP. I am trying to keep cost low.
