Due to a known problem in Intel® Quartus® Prime Pro Edition Software version 18.1 Update 1 and later, while attempting to reconfigure an Intel Stratix® 10 device via any of the supported configuration methods, including Configuration via Protocol (CvP), you may see the device get stuck and require a power cycle to recover.
This may be seen if the design uses Intel Stratix 10 Mailbox Client IP commands on its own for accessing the Stratix 10 Secure Device Manager peripherals or via software IPs such as Intel Stratix 10 Temperature Sensor / Intel Stratix 10 Voltage Sensor / Chip ID Intel Stratix 10 FPGA IP core / Stratix 10 Serial Flash Mailbox Client Intel FPGA IP core / Intel Stratix 10 Partial Reconfiguration Controller IP Core or HPS cold resets on Intel Stratix 10 Hard Processor System.
