Why does an Intel® Stratix® 10 device fail to reconfigure when using the Mailbox Client Intel® Stratix® 10 FPGA IP?


During user mode, Intel® Stratix® 10 device reconfiguration may fail when an attempt is made to trigger reconfiguration from any configuration source including reconfiguration with JTAG. This is due to the SDM Mailbox being busy processing the command from the  Mailbox Client Intel® Stratix® 10 FPGA IP.



To perform reconfiguration:

1. In each Mailbox Client IP, after issuing one request wait for the response.

2. After the response is received, assert the reset port of the Mailbox Client IP.

3. Wait for at least 1 second.

4. Assert the nCONFIG pin to start the reconfiguration.

This issue is scheduled to be fixed in a future version of the Intel® Quartus® Prime Pro software.
