Global architecture

The STM32CubeH5 demonstration firmware is composed of two subdemonstrations accessible from a main menu launcher:

  1. The TouchGFX graphics demonstration showing the TouchGFX framework capabilities of STM32H573I-DK. The demo is running in 16-bit color mode, with double frame buffers in internal SRAM and all assets stored in internal flash memory. To access the project code and reflash the TGFX subdemo, the user must use TouchGFXDesigner, which is available as a free download on st.com, refer to as X-CUBE-TOUCHGFX.
  2. STM32H573I demonstration: Based on a set of firmware and hardware services offered by the STM32Cube MCU Package and a set of modules mounted on the kernel and built in a modular architecture. Each module can be reused separately in a standalone application. The kernel, which provides access to all common resources and facilitates the addition of new modules, manages the full set of modules.
    • Azure® RTOS ThreadX is used for tasks scheduling and hence the switching between the different demonstration modules and submodules.
    • Each module must provide the following functionalities and proprieties:
    • a. Icon and graphical aspect characteristics
    • b. Method to start up the module
    • c. Method to safely close the module
    • d. The module application core (main module process)
    • e. Specific configuration
    • f. Error management
    • To build this demonstration separately, refer to the STM32Cube_FW_H5_V1.1.0 or later.
  • Note: A touchscreen controls the demonstration navigation.
  • Going back to the main menu the user needs to use the black reset button on the board.

  • System informationSTMicroelectronics-STM32H573I-DK-Discovery-Kit-STMicro-Mouser-FIG-8

TrustZone® controller modules Overview

  • TrustZone® technology within Arm® Cortex®‑M33 is an efficient solution to protect data and code.
  • It divides the system into two worlds, secure(trusted) and nonsecure (nontrusted). The Trust Zone controller (GTZC) encompasses peripherals, memory, software, interrupts, and bus transactions.

Contents

The global TrustZone® controller (GTZC) block contains the following subblocks:

  1. TZSC (TrustZone® security controller): This subblock defines the secure privileged state of the slave peripherals. It also controls the subregion area size and properties of the watermark memory peripheral controller (MPCWM). The TZSC informs some peripherals (such as RCC or GPIOs) about the security status of each securable peripheral, by sharing with RCC and I/O logic.
  2. MPCBB (Block-based memory protection controller): This subblock configures the internal RAM in a TrustZone®‑system product having segmented SRAM (512‑byte pages) with programmable security and privileged attributes.

In this context, two applications are offered in emulation mode to highlight these features (peripheral access control and memory access control).

Peripheral access control

  • The TrustZone® security controller defines the secure privileged state of the slave peripherals. Here is an example that simulates the behavior of LED (GPIO) and UART peripherals in a security context controlled by the GTZC.
  • It shows how a peripheral can be configured and provides the expected results during access to the peripheral in the security configuration.STMicroelectronics-STM32H573I-DK-Discovery-Kit-STMicro-Mouser-FIG-10
  • As shown in Figure 11. GTZC peripheral access interface, the user can configure in the configuration window the UART and the LED as secured or nonsecured peripherals.
  • Then, in the execution window, the user sets the access type that defines in which access mode the user performs the execution (secure or nonsecure access mode).
  • Finally, the user can check the result of the execution by pressing the button Print for the UART or Toggle for the LED.

Memory access control

  • The GTZC contains an important subblock for memory protection.
  • MPCBBblock-based memory protection controller: This subblock configures the internal RAM in a
  • TrustZone®‑system product having segmented SRAM (512‑byte pages) with programmable security and privileged attributes.
  • Based on the MPCBB block, this example shows how the GTZC can protect a specific memory region.
  • The example provides an on‑screen drawing application using the finger. This is a frame buffer memory writing in the corresponding address in the memory.
  • If the users touch with their fingers an area corresponding to the normal zone, a dot is drawn and a message displayed at the bottom of the screen mentioning that access to this address is authorized. Now, if the users touch with their fingers an area corresponding to the forbidden zone, nothing is drawn and a message is displayed at the bottom of the screen mentioning that access to this address is not allowed.

Audio module Overview

  • The serial audio interface (SAI) is a peripheral communicating with external audio devices supporting the most audio standards allowing an easy connection to any existing audio device.
  • Integrating a PDM interface, the SAI can connect up to eight digital microphones for beamforming or simple speech capture applications.

Contents

  • The SAI1 is configured to record PDM data from a digital microphone mounted on the board.
  • The STM32_Audio library is used to convert the PDM data into PCM audible data. The PCM data is played via audio codecs CS42L51 and SAI2.

Connected to an audio codec, the SAI is configured to:

  • Receive and store data from a digital microphone in DMA mode.
  • Transmit the received data for playback.
  • The module provides the options to start, stop, pause, and resume the recording and playback. For audio playback, the user must plug a headset into the audio jack.

USB-PD module

  • This module demonstrates the functionality of the USB-PD peripheral. The board can behave as a USB DeviceDevice or USB Host.
  • When a device is connected via a USB Type-C® cable, the board behaves as a mouse.
  • By tapping on the triangles, the mouse cursor moves.
  • By clicking on the Switch button, and connecting a device via a USB Type-C®, the USBPD command menu and device name are displayed on the screen.

The USBPD command menu is as follows:

  • Data Role Swap
  • Power Role Swap
  • Get Source/Sink capabilities

Data Role Swap:

  • USBPD command to switch the role between host and device (device acts as host and host acts as device).
  • If the Data Role Swap request is rejected, a rejection message is displayed.

Power Role Swap:

  • USBPD command to switch power role between power provider and power consumer (source/provider power acts as sink/consumer power and sink/consumer power acts as source/provider power).

Get Source capabilities:

  • Can be triggered by pressing the Get Source Capabilities menu. If the request is rejected, a rejection message is displayed. If the request is accepted, the source capabilities are displayed on the screen.

Get Sink capabilities:

  • Can be triggered by pressing the Get Sink Capabilities menu. If the request is rejected, a rejection message is displayed. If the request is accepted, the capacities of the Sink are displayed on the screen.STMicroelectronics-STM32H573I-DK-Discovery-Kit-STMicro-Mouser-FIG-15

Calendar module

  • This module shows the capabilities of the RTC peripheral to provide calendar functionalities:
  • Set and show the date.
  • Set and show the time.
  • Set and disable the alarm.
  • When the alarm is triggered, the green LED is toggling for a while.STMicroelectronics-STM32H573I-DK-Discovery-Kit-STMicro-Mouser-FIG-16

Cryptography module

  • An on‑the‑fly decryption engine (OTFDEC) is a peripheral that allows decryption during read operations without considerable losses in terms of execution time.
  • In this module, the OTFDEC is used with OCTOSPI to run an encrypted code from an external memory (cipher code).
  • The OCTOSPI is used to run the same code not encrypted from external memory (plain code).
  • To check OTFDEC performance, the execution time is calculated for both code running methods, and a comparison is done using a graph as shown in Figure 21.
  • For a better result display purpose, the execution time starts from three seconds.

System information module

  • The system information shows the main demonstration information such as the used board, the STM32CubeH5 demonstration firmware version, the MCU name, the board name, and the CPU clock.
