What can cause the Mailbox Client Intel® Stratix® 10 FPGA IP to stop functioning?

Description

The Mailbox Client Intel® Stratix® 10 FPGA IP may stop functioning when an attempt is made to send a write, read or erase command before setting the chip select using command QSPI_SET_CS.

Workaround/Fix

If using Intel® Quartus® Prime Pro Edition Software version 19.1 and below, a power-cycle of the Intel® Stratix® 10 device is required to recover from this condition.

If using Intel® Quartus® Prime Pro Edition Software version 19.2 and above, an error message will be prompted if the device is configured with non ASx4 configuration scheme. However, the QSPI_SET_CS command is optional if the device is configured with ASx4 configuration scheme.
