![]() On the target board, only the gdbserver binary is required for debugging Linux applications. Only the Developer Package can be used, since it is the only one which provides all the required components.Ĥ.2 Installing the GDB on your target board The symbols files of all BSP components ( TF-A, OP-TEE, U-Boot and Linux kernel), corresponding to the images of the OpenSTLinux Starter Package.Ĥ.1.1 Using the STM32MPU Embedded Software distribution 4.1.1.1 Developer Package.The OpenOCD binary and configuration files.This tool is made of two parts, one on the host PC, and a second on the target (only for debugging Linux applications).Ĥ.1 Installing the GDB tool on your host PC īelow is the list of required components: Refer to STM32MP15 reference manuals for information related to JTAG and SWD. These two modes are mutually exclusive since they share the same I/O pins. A 2-pin (clock + data) “serial-wire debug” port (SW-DP).A 5-pin standard JTAG interface ( JTAG-DP).The STM32MPU features two debug ports through the embedded CoreSight™ component that implements an external access port for connecting debugging equipment: arm-ostl-linux-gnueabi-gdb: embedded on host PC side, cross-compiled gdb binary that manages the connexion between the host computer and the target board.gdbserver: embedded on target rootfs and used as remote access for a host connection.Two components are included in OpenSTLinux Developer Package for GDB setup: In that case, only one software component is required on the host PC. gdb ↔ JTAG/ SWD path through OpenOCD and ST-LINK, used both for Cortex-M4 firmware and Cortex-A7 OpenSTLinux BSP components ( TF-A, OP-TEE, U-Boot and Linux kernel).In that case, two software components are required, one on the target and the other on the host PC. gdb ↔ gdbserver path through Ethernet, used for Cortex-A7 Linux applications.Two paths can be used in the STM32MPU environment for GDB setup: Update the program in order to test a bug correction, and jump to the next one.ģ Overview of GDB setup for STM32MPU 3.1 GDB setup paths.Examine what happened when the program stopped.Make the program stop on specific conditions.Start the program, specifying anything that might affect its behaviour.The GDB can perform four main types of actions (plus other corollary actions) to help you detect bugs when running your software or application: ** It is recommended to use the Developer Package to run the gdb debug session, which provided all dependencies * Cross compile gdb and openocd binaries are required and only available from Developer Package. The GNU Project debugger, GDB, allows monitoring program execution, or what the program was doing at the moment it crashed. You can contact our ST partner, Witekio, who can help you to port and maintain it on STM32MP15 platform. STM32MPU Embedded Software distribution for Android™ is no more supported by ST. STM32MPU Embedded Software distribution for Android™ : this tool is not present and cannot be integrated, or it is present but cannot be activated on the software package. : this tool is either present (ready to use or to be activated), or can be integrated and activated on the software package. The following table provides a brief description of the tool, as well as its availability depending on the software packages: It explains how to use this GNU debugger tool connected to your ST board target via Ethernet or via ST-LINK, and how to perform cross-debugging ( IDE, gdb viewer tool or command line) on Arm ® Cortex ®-A7 side for Linux ® application, Linux ® kernel (including external modules), or Arm ® Cortext ®-M4 firmware. This article provides the basic information needed to start using the GDB application tool. 5.4 Debug Linux application with gdbserver.5.3.2 Debug Cortex-M4 firmware in production boot mode.5.3.1 Debug Cortex-M4 firmware in engineering boot mode.5.2.6 To know more about Linux kernel debug with GDB.5.2.5 Running OpenOCD with custom boards.5.2.3 Configuring GDB and OpenOCD for attachment on boot. ![]() 5.2.2 Configuring GDB and OpenOCD for attachment on a running target. ![]()
