Intel Arria 10 AS Configuration Pins reuse for I/O

Hi,

Is it possible to use AS_DATA, DCLK , nCSo pins as a user I/O after FPGA configuration .(for Intel Arria 10 SoC)

Is it possible to use same flash for configuration and also for write/read access after configuration?

Thanks.

      Hi @Farabi ,

      Thanks for explanations and document. I see that these pins are not allowable for general I/O.

      However, what i want to do is using a QSPI Flash ( which is Micron MT25Q in my case) connected to AS pins of Intel Arria 10.

      Then by using a Generel Serial Flash Interface IP, i want to boot from QSPI Flash and also i want to read/write to additional part of the flash other than boot section.

      I think all following actions are possible with using GSFI IP for a QSPI Flash connected to AS pins:

      1. Boot from QSPI Flash through AS pins.

      2. Boot from SD/MMC AND use AS pins to read/write QSPI Flash.

      3. Boot from QSPI Flash through AS pins AND use AS pins to read/write QSPI Flash.

      Thanks
