5. Remote System Upgrade
Remote system upgrade implements device reconfiguration using dedicated remote
system upgrade circuitry available in all Intel Stratix 10 devices. Remote system
upgrade has the following advantages:
• Provides a mechanism to deliver feature enhancements and bug fixes without
recalling your products
• Reduces time-to-market
• Extends product life
Using remote system upgrade, you use the Intel Stratix 10 Serial Flash Mailbox Client
Intel FPGA IP to write configuration bitstreams to the AS x4 flash device, then instruct
the SDM to reboot from the updated image. You can store multiple application images
and a single factory image in the configuration device. Your design manages remote
upgrades of the application images in the configuration device.
A command to the Mailbox Client Intel Stratix 10 FPGA Mailbox Client IP Core initiates
reconfiguration. The remote upgrade system performs configuration error detection
during and after the reconfiguration process. If errors in the application images
prevent reconfiguration, the configuration circuitry reverts to the default factory image
and provides error status information.
The following figure shows functional diagrams for typical remote system upgrade
processes. For passive configuration schemes, the host implements remote system
update rather than the Intel Stratix 10 device. To learn more about remote system
update for passive configuration schemes, refer to Altera Remote Update IP Core User
Guide for remote system update implementations in earlier device families. This
document explains the remote system update implementation for active configuration
schemes.
