The block diagram below shows the STM32MPU 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, for STM32MP15x lines
and STM32MP25x lines , running on the Arm® Cortex®-M core
- The STM32MPU peripherals shared between Cortex®-A (on STM32 Arm® Cortex® MPUs ) and Cortex®-M (for STM32MP15x lines and STM32MP25x lines ) 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.
