Design Overview


This design module demonstrates the FreeRTOS and application running on RPU-0, where:

  • FreeRTOS boots on RPU-0

  • FreeRTOS application "heartbeat" prints periodic messages on UART-1





Design Components


  • petalinux_bsp

    • zynqmp_fsbl

    • pmufw

  • heartbeat.elf



Build Flow Tutorials


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

Heartbeat Application


The heartbeat application is a FreeRTOS application that executes on RPU-0 after the FSBL has finished. This application is a simple dual task application that demonstrates communication between the two tasks by printing messages to the UART1 console.

  • Create a new SDx workspace.

    % cd $TRD_HOME/workspaces/ws_heartbeat % xsdk -workspace . &&

  • Click 'Import Project' from the welcome screen, browse to the current working directory and make sure the heartbeat, heartbeat_bsp, and hw_platform_0 projects are selected. Click Finish.

  • Right-click on the heartbeat project and select 'Build Project'.

  • Copy the generated heartbeat executable into the PetaLinux BSP.

    cp heartbeat/Debug/heartbeat.elf $TRD_HOME/petalinux/bsp/images/linux


PetaLinux BSP


This tutorial shows how to build a boot image that includes the heartbeat 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/dm2.bif --force

  • Copy the generated boot image to the dm2 SD card directory.

    % mkdir -p $TRD_HOME/sd_card/dm2 % cp BOOT.BIN $TRD_HOME/sd_card/dm2



Run Flow Tutorial


  • See here for board setup instructions.

  • Copy all the files from the $TRD_HOME/sd_card/dm2 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 prints on UART-0 and prints from heartbeat application can be viewed on UART-1 which is shown in the following picture:
