5.1. Remote System Update Functional Description

5.1.1. Remote System Update Using AS Configuration

Remote system update using AS configuration includes the following components:
• Your external remote system update host design. The host can be custom logic, the HPS, or a Nios
FPGA.
• One factory image.
• Flash memory for image storage.
• At least one application image.
• Designs that do not use the HPS as the remote system update host require an Intel Agilex Mailbox Client FPGA IP core as
shown in the figure below. The Mailbox Client sends and receives remote system update operation commands and
responses. To perform RSU operations through a Intel Agilex device that does not include the HPS, you must use the Intel
Agilex Mailbox Client FPGA IP to issue commands. Optionally, you may use Intel Agilex Serial Flash Mailbox Client IP to
perform flash transactions, such as rewriting the application image to the serial flash.
