Return to the Design Tutorials Overview.

This module demonstrates:

• Boot RPU1 only

  • RPU1 OS: Bare-metal

• Bare-metal performance monitor application

  • Read PS APM counters to measure DDR throughput and prints to UART1

Open

This module requires the following components:

• pmu_fw

• petalinux_bsp

  • zynqmp_fsbl

• perfapm-ctl + perfapm

Please refer to design module 1 - PMU firmware for instructions or skip this step if you have built the PMU firmware in a previous module.

• Create a new XSDK workspace.

  % cd $TRD_HOME/rpu1/perfapm-server % 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 zcua02_base_trd_wrapper_hw_platform_0 projects are selected. Click Finish.
  
  

  Open

  

• 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/apu/petalinux_bsp/images/linux

This tutorial shows how to build the first stage bootloader (FSBL) and boot image using the PetaLinux build tool.

• The petalinux-config step can be skipped if this was already done in a previous module.

  % cd $TRD_HOME/apu/petalinux_bsp % petalinux-config --get-hw-description=./hw-description --oldconfig

• Build the FSBL. This step can be skipped if this was already done in a previous module.

  petalinux-build -c bootloader

• Create a boot image

  % cd images/linux % petalinux-package --boot --bif=dm3.bif --force

• Copy the generated boot image to the dm3 SD card directory

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

• See here for board setup instructions.

• Copy all the files from the $TRD_HOME/images/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.

• The user can now see FSBL and PMU-firmware prints on UART-0 and prints from baremetal Perfapm-ctl application can be viewed on UART-1 which is shown in the following picture:
