Zynq UltraScale MPSoC Base TRD 2017.4 - Design Module 4

Zynq UltraScale MPSoC Base TRD 2017.4 - Design Module 4

Design Overview


This module demonstrates:
  • Boot RPU1 from APU master via remoteproc
  • Inter Process Communication (IPC)
    • APU master: RPMsg
    • RPU1 remote: OpenAMP
  • RPU1 Bare-metal application (server)
    • Reads performance counters and sends to APU
  • APU Linux application (client)
    • Receives performance counters from RPU1 and prints to UART0





Design Components


This module requires the following components:
  • petalinux_bsp
    • zynqmp_fsbl
    • pmufw
    • bl31
    • u-boot
    • kernel
    • device tree (zcu102-base-dm4.dtsi)
    • rootfs
  • perfapm-server + perfapm
  • perfapm-client-test + perfapm-client



Build Flow Tutorials


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

Perfapm-server Application


The performance monitor server application perfapm-server is a bare-metal application that executes on RPU-1. The firmware binary is loaded by the APU master at the end of the Linux boot process. RPU-1 and APU establish a communication channel using the OpenAMP framework. RPU-1 gathers performance data like memory throughput from the PS AXI performance monitor (APM) units and sends it across to the APU where the data is received by the perfapm-client library and then visualized on a plotted graph.

  • Create a new SDx 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-server, perfapm_bsp, and zcu102_base_trd_wrapper_hw_platform_0 projects are selected. Click 'Finish'.
  • Right-click on the perfapm-server project and select 'Build Project'.
  • Copy the generated perfapm-server executable to the dm4 SD card directory.
    % mkdir -p $TRD_HOME/images/dm4
    % cp perfapm-server/Debug/perfapm-server.elf $TRD_HOME/images/dm4/

Perfapm-client-test Application


The application receives performance counter values from RPU-1 and prints them to UART-0.

  • Create a new SDx workspace.
    % cd $TRD_HOME/apu/perfapm-client
    % sdx -workspace . &&
  • Click 'Import Project' from the welcome screen, browse to the current working directory and make sure the perfapm-client and perfapm-client-test projects are selected. Click 'Finish'.
  • Right-click on the perfapm-client-test project and select 'Build Project'.
  • Copy the generated perfapm-client-test executable to the dm4 SD card directory.
    % cp perfapm-client-test/Debug/perfapm-client-test.elf $TRD_HOME/images/dm4

PetaLinux BSP


This tutorial shows how to build the Linux image 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 --oldconfig
  • Select the device-tree matching design module 4 and build all Linux image components. If you have run petalinux-build in a previous module, the build step will be incremental.
    % cd project-spec/meta-user/recipes-bsp/device-tree/files/
    % cp zcu102-base-dm4.dtsi system-user.dtsi
    % petalinux-build
    % cd -
  • Create a boot image
    % cd images/linux
    % petalinux-package --boot --bif=dm4.bif --force
  • Copy the generated images to the dm4 SD card directory
    % cp BOOT.BIN image.ub $TRD_HOME/images/dm4/



Run Flow Tutorial


  • See here for board setup instructions.
  • Copy all the files from the $TRD_HOME/images/dm4 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.
  • Run the perfapm-client-test application:
    % perfapm-client-test.elf
  • Below is a screenshot of the application output on the serial console:
