Perfapm-ctl Application

• Create a new Vitis workspace.

  Code Block
  language bash theme Midnight
  % cd $TRD_HOME/workspaces/ws_perfapm-ctl % xsdk -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 perfapm, perfapm-ctl and  projects are selected. Click Finish.

• Double click on 'perfapm-serverctl_system.sprj' and close the dialog box for platform.

Image RemovedImage Added

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

    Image RemovedImage Added

• 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.

Image RemovedImage Added

• In the System Project Settings tab, Add the new custom platform generated from xsa. Click Yes on the dialog box, when prompted to change the platform.

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

Image RemovedImage Added

• modify BSP settings for Cortexr5_1 processor

Image RemovedImage Added

• 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

• Create a boot image

  Code Block
  language bash theme Midnight
  % 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

  Code Block
  language bash theme Midnight
  % 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

  Code Block
  theme Midnight
  Turn on traffic generator? Enter 'Y' or 'N':

  
  

• View the application prints on UART-1 as shown in the pictures:
