Reference design is available on:
Design Flow
Hart Software Services (HSS)
This is Hart Software Services (HSS) code.On PolarFire SoC, this is comprised of two portions:
A superloop monitor running on the E51 minion processor, which receives requests from the individual U54 application processors to perform certain services on their behalf;
A Machine-Mode software interrupt trap handler, which allows the E51 to send messages to the U54s, and request them to perform certain functions for it related to rebooting a U54.
The HSS performs boot and system monitoring functions for PolarFire SoC. The HSS is compressed (DEFLATE) and stored in eNVM. On power-up, a small decompressor wrapper inflates the HSS from eNVM flash to L2-Scratchpad memory and starts the HSS.
Creating HSS workspace in SoftConsole
- Download the test board design zip file in the following path : ???
- Unzip the test board zip file
- Copy the HSS folder (hart-software-services-<HSS version>) from softconsole_source folder in the SoftConsole workspace folder
- Open SoftConsole software as administrator
- Select correct directory as workspace directory. The workspace folder must consist of hart-software-services-<HSS version> folder.
- Left click on board folder
- There is created already a subfolder for TEM0007 module and HSS is ready to be compiled as shown:
- Right click on hart-software-services-<HSS version> and click on Build project to compile it.
- It is ready to program created hex file on the Polarfire SoC. See Programming
Note that HSS can be changed for every TEM0007 variant. Therefore the hex file for every variant is created and saved in the following path of test design folder separately: (prebuilt/soctware/<short name of the module variant>)
Creating XML file in PolarfireSoC MSS Configurator Software
To create HSS file for a desired module variant the saved MSS configuration xml file in soc_fpgs_design/xml/ folder must be matched for its related xml file. To do it:
- Open the PolarfireSoC MSS Configurator software.
- Click on Project→Open
- Select the generated TEM0007_MSS.cfg file that is saved in the libero_source/mss folder while creating the Libero design.
- Click on Generate icon. It will be opened a window to enter the desired path for generated xml file.
- MSS configuration xml file is generated. This file must be imported in SoftConsole software. To import this file copy the generated MSS configuration xml file and replace it with previous xml file in the following path ( <softconsole workspace folder>/ hart-software-services-<HSS version>/boards/TEM0007/soc_fpga_design/xml ).
- In SoftConsole software click on Project/Clean.
- In SoftConsole software delete all configuration header files in hart-software-services-<HSS version>/boards/TEM0007/fpga_design-config folder.
- In SoftConsole software compile HSS again by clicking on Project/Build Project.
- The new configuration header files will be generated again by the python script in hart-software-services-<HSS version>/tools/polarfire-soc-configuration-generator/mpfs_configuration_generator.py folder. The generated hex file can be found in the hart-software-services-<HSS version>/Default folder.
- This new hex file must be replaced in Libero to generate new Bitstream file, if this hex file should be attached in Bitstream file. See Libero SoC
Libero SoC
Reference Design is available with and without prebuilt files. It's recommended to use TE prebuilt files for first launch.
Trenz Electronic provides a tcl based built environment based on Libero Design Flow.

Programming
Check Module and Carrier TRMs for proper HW configuration before you try any design.
Programming eNVM
The eNVM is a user non-volatile flash memory that can be programmed independently. There is two methods to program eNVM:
Programming eNVM in SoftConsole
To program HSS *.elf file on FPGA:
- Prepare the hardware see Hardware Setup
- Open SoftConsole software as administrator, if it is not done yet.
- Select correct directory as workspace directory.
- Build the hart-software-services-master , if it is not done yet.
- Click on Run > External Tools > Polarfire SoC program non-secure boot-mode 1
Programming eNVM in Flashpro Express
The HSS generated hex file can be attached to bitstream file. For more information see Design Flow
To program the eNVM in Flashpro Express see #Using FlashPro Express
Programming Bitstream
There is two ways to program bitstream file on FPGA:
Using Libero SoC
- Connect the TEM0703 board via its Mini-USB connector. (J4)
- After generating bitstream in Libero click on Run PROGRAM Action to program bitstream file on FPGA.
Using FPExpress software

SD-Boot mode
This module supports SD card boot mode. There is no dip switch to select boot mode. The selection between SD card or other boot mode will be done in HSS. TEM0007 module supports SD card boot mode and JTAG boot mode.
Prepare SD card as follows for SD card boot mode:
- Extract SD_Card.zip file
- Now there is a image file (SD_Card.img)
- Alternative SD card can be written via Win32DiskImager or balenaEtcher softwares in Windows OS.
- In the case of writing image file in linux there are two commands to write image file on the SD card after mounting SD card in the host linux same as WSL:
- Insert SD card in the SD card reader
bmaptool copy --nobmap <Path of image file *.img> /dev/sdX
- After mounting the SD card in linux the name of SD card recognized via lsblk command. For example SD card name can be sda or sdb.
dd if=<Path of image file *.img> of=/dev/sdX
- After mounting the SD card in linux the name of SD card recognized via lsblk command. For example SD card name can be sda or sdb.
JTAG
Not used on this example.
Usage

WEEE
Information for users within the European Union in accordance with Directive 2002/96/EC of the European Parliament and of the Council of 27 January 2003 on waste electrical and electronic equipment (WEEE).
Users of electrical and electronic equipment in private households are required not to dispose of waste electrical and electronic equipment as unsorted municipal waste and to collect such waste electrical and electronic equipment separately. By the 13 August 2005, Member States shall have ensured that systems are set up allowing final holders and distributors to return waste electrical and electronic equipment at least free of charge. Member States shall ensure the availability and accessibility of the necessary collection facilities. Separate collection is the precondition to ensure specific treatment and recycling of waste electrical and electronic equipment and is necessary to achieve the chosen level of protection of human health and the environment in the European Union. Consumers have to actively contribute to the success of such collection and the return of waste electrical and electronic equipment. Presence of hazardous substances in electrical and electronic equipment results in potential effects on the environment and human health. The symbol consisting of the crossed-out wheeled bin indicates separate collection for waste electrical and electronic equipment.
Trenz Electronic is registered under WEEE-Reg.-Nr. DE97922676.
