The APU and RPU come under the processor-based subsystems. For all processor-based subsystems, ELF files and/or CDOs are present as a part of the image. Processor details are read from image headers and the processor is initialized using XilPM commands.

The configuration consists of the following files.

File Contents
PSM/RPU/APU CDO files
  • (Optional) Set of PM commands with nodes and requirements
PSM/RPU/APU ELF files
  • Cortex-R5F processor applications: Bare- metal/RTOS
  • Cortex-A72 processor applications: TF-A/U-Boot/Linux/Bare-metal
  • For loading Cortex-R5F processor applications, ensure that the LPD configuration is completed.
  • For loading Cortex-A72 processor applications, ensure that the FPD configuration is completed.
  • For loading Cortex-R5F/Cortex-A72 using DDR memory, ensure that the PL (NPI with DDR configuration) configuration is completed.
  • For loading Cortex-R5F/Cortex-A72 processor applications to the DDR memory, enable the NoC path from the PMC to the DDR memory in the design.
