Zynq UltraScale+ MPSoC Base TRD 2020.1 - Design Module 3

Design Overview

This module demonstrates:

Boot RPU1 only
- RPU1 OS: Bare-metal
Bare-metal performance monitor application
- Reads PS APM counters to measure CCI, Core Switch and DDR throughput and latency, then prints them to UART1

Design Components

This module requires the following components:

petalinux_bsp
perfapm-ctl

Build Flow Tutorials

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

Perfapm-ctl Application

Create a new Vitis workspace.

% cd $TRD_HOME/workspaces/ws_perfapm-ctl
% vitis -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.

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

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.

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

modify BSP settings for Cortexr5_1 processor

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

This tutorial shows how to build a boot image that includes the perfapm-ctl 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/dm3.bif --force

Copy the generated boot image to the dm3 SD card directory

% 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
```
Turn on traffic generator? Enter 'Y' or 'N':
```

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