Arria 10 series has dedicated 3 CS for the flash devices.

What is the use case of 3 Chip select of the external flash device ?

So By default we connect CS_0 ​to the flash device. If we have 3 flash devices and if FPGA wants to fetch the configuration file from 2nd flash , how it asserts the CS_1 ?

Hi SB S,

By default, it will configure the FPGA with configuration devices connected to nCS[0]. Then later on, user can reconfigure the FPGA in user mode with configuration data in another configuration devices connecting to nCS[1] or nCS[2] with a host.
