custom serial flash interface at ARRIA 10 GX

Hi Sree,

You understand correctly.

the flash I use is Micron Serial NOR Flash N25Q512A.

My block implement SPI protocoll using signals: flash_csn, flash_si , flash_so, flash_wpn , flash_holdn, flash_clk .

With this interface I execute READ, WRITE, EARASE and others commands.

I used the same block with cyclone 10 LP FPGA and it's work perfect. At the cyclone 10 I configure the flash pins (DCLK, DATA0, DATA1..)

to be dual purpose pins.

If you have solution for me that will be great.

Niv.
