Pin Mapping

The Trusted Platform Module (TPM) is an incorporated security module that serves as a hardware-based authentication mechanism. This module is primarily utilized for generating, storing, and managing cryptographic keys, as well as securely storing digital certificates.

The Libero SoC Design Suite is responsible for generating the programming bitstream used in different programming modes. These bitstreams can consist of various components, depending on the specific requirements. These components may include:

1. FPGA fabric logic
2. sNVM data
3. eNVM data
4. User security settings:

You may choose the components you want to program using the Configure Bitstream dialogue box. Right-click Generate Bitstream in the “Design Flow” window and select Configure Options to bring up the dialogue box.

In order to configure the EagleCore PolarFire SoC SOM using JTAG, it is necessary to have a carrier board, such as <Numato Lab’s carrier board>, which is equipped with a JTAG connector. The JTAG controller communicates with the system controller by sending the JTAG instruction to be executed and a 128-bit data buffer that conveys any accompanying data. EagleCore PolarFire SoC SOM can be programmed via the specific JTAG interface with a Microchip FlashPro programmer (version 5 or later). This can be done either using the Libero SoC or a standalone FlashPro Express.

Step 1: Connect the Microchip FlashPro programmer to the EagleCore PolarFire SoC SOM and power it up.

Step 2: In Libero SoC, double-click the Run PROGRAM Action under “Program Design” to program the specific component that was selected while generating the bitstream (Fabric, sNVM, eNVM, etc.).

Step 1:

Go to Design Flow > Program and Debug Design > Configure Design Initialization Data and Memories, and choose the SPI Flash tab. Add the required programming images under the SPI Flash Clients section and then click on the “Apply” button to save the changes.

Step 2:

To program the SPI flash with the SPI directory and the programming images, simply double-click on the Run PROGRAM_SPI_IMAGE Action.

Step 1:

Run the Export FlashPro Express Job command in Libero to create a container for the programming configuration data, including programming files, to be sent to the production programming tool FlashPro Express.

Step 2:

Select New Job Project from the Project menu in FlashPro Express. In the Create New Job Project window provide the file path where you exported the Programming Job file from Libero, as well as the preferred location where you intend to store the FlashPro Express job project.

Step 3:

Connect the Microchip FlashPro programmer to the EagleCore PolarFire SoC SOM and power it up.

Step 4:

Once the Job project is open, make sure the Programmer is listed.

Set PROGRAM as the Programming Action from the drop-down menu.

Click on RUN.
