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 XSDK and PetaLinux tools. It is recommended to use separate shells for each of the tools.

Perfapm-ctl Application

• Create a new SDx workspace.

  % cd $TRD_HOME/workspaces/ws_perfapm-ctl % xsdk -workspace . &

  
  

• Click 'Import Project' from the welcome screen, browse to the current working directory and make sure the perfapm, perfapm_bsp, perfapm-ctl and hw_platform_0 projects are selected. Click Finish.
  
• Right-click on the perfapm-ctl project 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:
