Zynq UltraScale+ MPSoC Base TRD 2020.1 - Design Module 3

Table of Contents



Design Overview


This module demonstrates:
  • Boot RPU1 only
    • RPU1 OS: Bare-metal
  • Bare-metal performance monitor application
    • Reads PS APM counters to measure CCI, Core Switch and DDR throughput and latency, then prints them to UART1




Design Components


This module requires the following components:
  • petalinux_bsp
  • perfapm-ctl


Build Flow Tutorials


This tutorial uses both Vitis and PetaLinux tools. It is recommended to use separate shells for each of the tools.

Perfapm-ctl Application

  • Create a new Vitis workspace.

    % cd $TRD_HOME/workspaces/ws_perfapm-ctl
    % vitis -workspace . &
  • Click 'Import Project' from the welcome screen, Choose 'Eclipse workspace' and select next.
  • Uncheck 'copy projects into workspace', browse to the current working directory and make sure the perfapmperfapm-ctl and  projects are selected. Click Finish.

      

  • from the top menu tab choose 'File' →  'New platform', enter Project name as 'hw_platform_0' and select 'Next'.

    

  • Choose 'Create from hardware specification (XSA)' and browse to the xsa file in the 'hwfile' directory of 'ws_heartbeat workspace',
  • Select operating system as 'standalone' and processor as 'psu_cortexr5_1' and click Finish.

  • double click on 'perfapm-ctl.prj' in the Elplorer tab, and click 'Navigate to BSP settings'

  • modify BSP settings for Cortexr5_1 processor

  • under overview panel enable libraries 'libmetal' and 'openamp'.

                                       

  • under standalone sttings modify 'stdin/stdout' to 'psu_uart_1', select ok.

                                      

  • Right-click on the perfapm-ctl system and select 'Build Project'.

                                       

  • Copy the generated perfapm-ctl executable into the PetaLinux BSP.
% cp perfapm-ctl/Debug/perfapm-ctl.elf $TRD_HOME/petalinux/bsp/images/linux

PetaLinux BSP


This tutorial shows how to build a boot image that includes the perfapm-ctl application using the PetaLinux build tool. This step assumes you have run through the PetaLinux build in DM1 previously
  • Create a boot image

    % cd $TRD_HOME/petalinux/bsp/images/linux
    % petalinux-package --boot --bif=../../project-spec/boot/dm3.bif --force
  • Copy the generated boot image to the dm3 SD card directory

    % mkdir -p $TRD_HOME/sd_card/dm3
    % cp BOOT.BIN $TRD_HOME/sd_card/dm3

Run Flow Tutorial

  • See here for board setup instructions.
  • Copy all the files from the $TRD_HOME/sd_card/dm3 SD card directory to a FAT formatted SD card.
  • Power on the board to boot the images; make sure all power rail LEDs are lit green (Note: DS1 / FPGA_INIT_B LED remains Red as there is no bit stream to configure the FPGA).
  • The user can now see FSBL prints on UART-0 and prints from bare-metal perfapm-ctl application can be viewed on UART-1.
  • When prompted, user need to press 'Y' to turn on a dummy traffic generator that reads from OCM

    Turn on traffic generator? Enter 'Y' or 'N':
  • View the application prints on UART-1 as shown in the pictures:
