The platform loader and manager (PLM) runs on the platform processing unit (PPU) in the platform management controller (PMC). It performs boot and configuration of the Versal device, and then continuously provides services after the initial boot and configuration.
During the initial boot, the BootROM decodes the programmable device image (PDI) and loads the PLM into the PPU RAM. The PPU PLM processes the PDI to boot up the entire system by loading the partitions present in the PDI. The PLM supports the loading of partial PDIs during run time. See Versal ACAP Technical Reference Manual (AM011) for more information.
