STM32MP1 Platform trace and debug environment overview

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 running on the Arm^® Cortex^®-M core

• The STM32MPU peripherals shared between Cortex^®-A and Cortex^®-M 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.
