Tutorials ¶

Get started with STM32Cube HAL and Nucleo-F401RE: debugging and unit testing

Configuration ¶

Warning

For the JTAG probes implemented as USB devices (actually most of them), you need to configure the UDEV subsystem:

Linux Users: Install “udev” rules file 98-openocd-udev.rules (an instruction is located inside a file).

Windows Users:: Please check that you have a correctly installed USB driver from board manufacturer

PIO Unified Debugger can be configured from Project Configuration File platformio.ini

debug_tool
debug_init_break
debug_init_cmds
debug_extra_cmds (conditional project breakpoints, extra configuration, etc.)
debug_load_cmd
debug_server
debug_port

Tools ¶

You can change debugging tool via debug_tool option.

The Black Magic Probe is a modern, in-application debugging tool for embedded microprocessors. It is able to control and examine the state of the target microprocessor using a JTAG or Serial Wire Debugging (SWD) port and on-chip debug logic provided by the microprocessor. The probe connects to a host computer using a standard USB interface.

Also, see Custom debugging configuration with Black Magic Probe.

CMSIS-DAP ¶

debug_tool = cmsis-dap

CMSIS-DAP is generally implemented as an on-board interface chip, providing direct USB connection from a development board to a debugger running on a host computer on one side, and over JTAG (Joint Test Action Group) or SWD (Serial Wire Debug) to the target device to access the Coresight DAP on the other.

J-LINK ¶

debug_tool = jlink

SEGGER J-Links are the most widely used line of debug probes available today. They’ve proven their value for more than 10 years with over 400,000 units sold, including OEM versions and on-board solutions. This popularity stems from the unparalleled performance, extensive feature set, large number of supported CPUs, and compatibility with all popular development environments.

MSP Debug ¶

debug_tool = mspdebug

The MSP debug stack (MSPDS) for all MSP430™ microcontrollers (MCUs) and SimpleLink™ MSP432™ devices consists of a static library on the host system side as well as an embedded firmware that runs on debug tools including the MSP-FET, MSP-FET430UIF or on-board eZ debuggers. It is the bridging element between all PC software and all MSP430 and SimpleLink MSP432 microcontroller derivatives and handles tasks such as code download, stepping through code or break points
