GUIDELINE: When configuring FPGA from flash, select a compatible QSPI device.

GUIDELINE: Select the QSPI device that fits your design. Using a larger device allows for increases in the design bitstream size.

GUIDELINE: Do not reset the quad SPI flash when used as the configuration device and data storage device with FPGA.

If you reset the quad SPI flash during the FPGA configuration and reconfiguration, or when the QSPI is in READ, WRITE, and ERASE operations, this causes undefined behavior for quad SPI flash and the FPGA. To recover from the unresponsive behavior, you must power cycle your device. To reset the quad SPI flash using the external host, you must first complete the FPGA configuration and reconfiguration, or a quad SPI operation, and only then toggle the reset. The quad SPI operation is complete when the exclusive access to the quad SPI flash is closed by issuing the QSPI_CLOSE command from the Mailbox Client Intel® FPGA IP or CLOSE command from the Serial Flash Mailbox Client Intel® FPGA IP.
