Reconfiguration of Intel® Stratix® 10 devices in Active Serial (AS) mode may fail if a system asserts the external reset of the serial flash device used for configuration before reconfiguration is triggered
This is because the Secure Device Manager (SDM) sets initialization values in the serial flash device during the first configuration of the Intel Stratix 10 device but doesn’t set them again during reconfiguration.
Hence, if the serial flash device is reset before reconfiguration, the initialization values are eliminated causing reconfiguration to fail.
To work around this problem, do not reset the serial flash device prior to a reconfiguration.
