Greybox implementation supports INI interfaces for the NoC. The DFX greybox flow inserts NMUs or NSUs in the RP to provide a legal Endpoint for the boundary NoC network. This enables you to take advantage of the benefits of greybox PDI, including smaller partial PDI size, lower dynamic power consumption in hardware, and faster PDI download. However, this does not mean that the NoC Endpoints are accessible in the hardware when the greybox partial PDI is loaded. Do not try to access NSUs without attached peripherals, which can lead to unpredictable behavior within the NoC network and might even require a system reset. To ensure a successful operation, make sure your software or hardware applications do not access peripherals in the dynamic region when the greybox partial PDI is being downloaded.
