The block diagram below shows the STM32MP1 Platform trace and debug environment components and their possible interfaces:

  • The STM32MPU Embedded Software package (see STM32MPU Embedded Software architecture overview) that includes:
    • The OpenSTLinux BSP and application frameworks components, running on the Arm® Cortex®-A core
    • The STM32Cube MPU Package, on STM32MP15x lines More info.png only, running on the Arm® Cortex®-M core
  • The STM32MPU peripherals shared between Cortex®-A (on STM32MP1 Series) and Cortex®-M (on STM32MP15x lines More info.png only) cores (such as GPIO, I2C and SPI)
  • The user interfaces or tools, which allow to interact with different trace and debug Tools, such as:
    • The remote shell using terminal console
    • The debugger tools (such as GDB)
    • The graphical IDE (such as GDBGUI or SystemWorkbench)
  • The trace and debug interfaces or hardware paths that provide access to trace and debug components through:
    • The network interface (e.g. Ethernet)
    • The communication port (e.g UART)
    • The hardware connector interfaces:
      • JTag port
      • Trace port to access ETM, STM, ITM and SWD
      • I/O probes to access HDP
  • The hardware probes such as ST-Link.


This block diagram also illustrates the Arm® debugging modes:

  • Invasive debug: debug process that allows the control and monitoring of the processor. Most debug features are considered invasive because they enable you to halt the processor and modify its state.
  • Non-invasive debug: debug process that allows the monitoring of the processor but not the control. The embedded trace macrocell (ETM) interface and the performance monitor registers are non-invasive debug features.
