Design Overview

• 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

• Make sure you have sourced the SDX settings64.sh script before executing the below steps. This will add the ARM cross-compile toolchain to your PATH and set the XILINX_SDX environment variable.

• Copy and extract the source files into a new workspace.

  Code Block
  theme Midnight
  % mkdir -p $TRD_HOME/workspaces/ws_perfapm-client % cd $TRD_HOME/workspaces/ws_perfapm-client % cp $TRD_HOME/petalinux/bsp/project-spec/meta-user/recipes-apps/perfapm-client/files/perfapm-client.zip . % unzip perfapm-client.zip % mkdir build work

  
  

• Configure the project using cmake and generate eclipse project files. Build the project using make from the command line.  

  Code Block
  language bash theme Midnight
  % cd build % CC=aarch64-linux-gnu-gcc CXX=aarch64-linux-gnu-g++ \ cmake -G"Eclipse CDT4 - Unix Makefiles" -DCMAKE_ECLIPSE_EXECUTABLE=${XILINX_SDX}/eclipse/lnx64.o/eclipse \ ../src % make -j

  
  

• Alternatively you can build the project through the XSDK GUI.

  Code Block
  language bash theme Midnight
  % cd ../work % xsdk -workspace . &

  
  

• Click 'Import Project' from the welcome screen, browse to the $TRD_HOME/workspaces/ws_perfapm-client/build directory and make sure the listed project is selected. Click 'Finish'. 
• Right-click the project and select 'Build Project'.
  

• Copy the generated perfapm-client-test executable to the dm4 SD card directory.

  Code Block
  language bash theme Midnight
  % cp $TRD_HOME/workspaces/ws_perfapm-client/build/perfapm-client-test/perfapm-client-test $TRD_HOME/sd_card/dm4

  
  

PetaLinux BSP

• 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.

  Code Block
  language bash theme Midnight
  % cd $TRD_HOME/petalinux/bsp/project-spec/meta-user/recipes-bsp/device-tree/files/ % cp zcu102-base-dm4.dtsi system-user.dtsi % petalinux-build

  
  

• Create a boot image

  Code Block
  language bash theme Midnight
  % cd $TRD_HOME/petalinux/bsp/images/linux % petalinux-package --boot --bif=../../project-spec/boot/dm4.bif --force

  
  

• Copy the generated images to the dm4 SD card directory

  Code Block
  language bash theme Midnight
  % cp BOOT.BIN image.ub $TRD_HOME/sd_card/dm4

  
  

Run Flow Tutorial

• See here for board setup instructions.
• Copy all the files from the $TRD_HOME/sd_card/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 (Note: DS1 / FPGA_INIT_B LED remains Red as there is no bit stream to configure the FPGA).

• Run the perfapm-client-test application:

  Code Block
  language bash theme Midnight
  % perfapm-client-test

  
  

• Below is a sample output of the application on the serial console:
