Quicklinks

If you know what you are doing, you can directly skip to:

In Eclipse, open the project you wish to configure. Click on 'Project/Properties' in the main menu. Note: There is a shortcut to manage all the launch configurations in the entire workspace in the pull-down menu below the green 'Run' button on the main Eclipse toolbar. The dialog window looks a little different than below because it shows just. To install and setup the Eclipse IDE, first download Java Development Kit (Java JDK) because Eclipse is a Java-based IDE; second, download Minimalist GNU for Windows (MinGW) as the compiler; and third, download Eclipse Integrated Development Environment (Eclipse IDE) for C/C. BTW this has nothing to do with eclipse, it is just how programming works. Note than C is the ancestor of C, so knowing C is always useful with C.

Overview

When debugging Arm applications, generally two main componentsare required:

  • a hardware JTAG/SWD probe
  • several software components

The hardware probe can be either a separate device, connected via a flatcable to the debugged board, or, for many affordable discoveryboards, can be directly integrated on the evaluation board, havinga separate USB connector.

For several specific cases, the hardware probe is not mandatory,debugging being possible inside emulators, like QEMU.

As for software, debugging is generally a complex operation, andin Eclipse it requires multiple components:

  • one or more Eclipse Debugging plug-ins
  • the GDB debugger (client) application
  • the GDB server application
  • the hardware drivers required by the JTAG/SWD probe

Eclipse C++ Windows

The Eclipse Embedded CDT project recommends three debugging solutions:

  • the SEGGER J-Link probe & GDB server, as a highly professionalsolution, supporting both JTAG and SWD, plus SWO trace output;
  • the OpenOCD application as an universal tool, supportingmost cheap JTAG probes, but with limitations (currently it doesnot support SWD and implicitly no SWO, it is slower, configurationmight be sometimes cryptical, there are many driver incompatibilitieson Windows, etc);
  • the xPack QEMU Arm emulator,supporting several Cortex-M boards.

For an explanation why the SEGGER J-Link was selected, please go tothe J-Link Debugging page and readthe introduction section.

GDB client

The GDB client (GDB stands for GNU Debugger) is part of theGNU Toolchains, and is located in the same folder as all GNU toolchainbinaries (compiler, linker, etc). The application name uses the sameprefix/suffix as the compiler (for example, the debugger for embeddedapplications is arm-none-eabi-gdb).

To check if GDB is functional on your machine, use the followingcommand (adjust the path for your system):

The presence of a GDB as part of a GNU toolchain is mandatory, andit is recommended that the version of the GDB client matches thetoolchain version. Generally only debugging .ELF applications ispossible, and these applications must be compiled to include GNUcompatible debugging information (like dwarf).

Non-GNU toolchains

Debugging applications generated by non-GNU toolchains(like the obsolete Arm CC), although not completely excluded,is not supported.

GDB server & drivers

Eclipse C++ Install

For the GDB server, there are three recommended solutions,J-Link GDB Server, OpenOCD and QEMU. Detailedinstallation instructions are available in separate pages:

Eclipse c++ install

Normally if you already have a J-Link probe (or an OpenSDA J-Linkcompatible evaluation board), there is no absolute need to installOpenOCD, but it is sometimes useful to have a back-up solution incase you want to compare different behaviours, so the recommendationis to have both installed.

Similarly, if you do not have a J-Link (yet), there is no need toinstall the J-Link support at this moment; you can very well startyour tests with OpenOCD alone. However, especially if your evaluationboard has an integrated JTAG, once you overcome the initial apprenticestatus and want to use more advanced debug techniques, like SWO traces,or even want to debug your own boards, you will need an external JTAG,and in this case the recommended solution is to use J-Link.

Alternate solutions

C++ In Eclipse

J-Link and OpenOCD are not the only existing solutions, but probablyare the most portable ones. J-Link is a single piece of hardware thatcan be used with most Arm processors. At the other end of the spectrumis OpenOCD, a single piece of software that, within limits, can beused with most JTAG probes, especially on GNU/Linux.

If portability is not your concern, and you prefer other GDB servers,please feel free to use them, but Eclipse Embedded CDT does not providesupport for them.

To save you time, we compiled a list of other GDB servers, with some of their features and limitations:

  • the original STM32 ST-Link Utility software, available from STM aspart numberSTSW-LINK004,also implements a GDB server for the ST-LINK probes; runs on Windows only
  • the stlink GDB server from texane, aGitHub project, implements the ST-LINKprotocol; can be compiled from sources on GNU/Linux and macOS; on Windowscan be compiled using mingw;
  • the CooCox GDB server; supports multiple JTAG probes; runs on Windows only
  • the Atollic GDB server, part of the Atollic suite; the server seems to start separately, but attempts to connect to it fail, probably due to someprotection checks

OpenSDA

Another interesting solution is Freescale’s OpenSDA debug/programminginterface. For the Kinetis L based Freedom Development Boards, SEGGERprovides a high performanceOpenSDAimplementation fully compatible with the J-Link Lite, so the J-Linkplug-in can be successfully used for these evaluation boards withouthaving a physical J-Link probe. More details on installing OpenSDAcan be found onMCU on Eclipse.

Eclipse debugging plug-ins

Eclipse Ide For C C++ Developers

The debugging plug-ins come together with the other Eclipse Embedded CDTplug-ins; if you install the full Eclipse IDE for Embedded C/C++ Developers,package, they are includded; if you use an alternate install method thedebug plug-ins should be installed in the same step, detailed in the[plug-ins install]/plugins/install-alternate/ page.

Eclipse For C In Linux

Be sure you enable the entries named Embedded C/C++ J-Link Debugging,Embedded C/C++ OpenOCD Debugging and Embedded C/C++ QEMU Debugging.

Jiffy Lube® is a lot more than a fast oil change! We also offer Transmission Service. Automatic Transmission Drain and Fill Automatic transmission fluid lubricates, cools and cleans internal components of the transmission. Jiffy Lube® removes the used fluid and replaces it with new transmission fluid that meets or exceeds your manufacturer's specifications. HOW IT WORKS: Transmission fluid helps lubricate, cool and clean internal components of the transmission. It also helps maintain the hydraulic pressure necessary for the transmission to function properly. HOW OFTEN: Transmission fluid should be exchanged at your. Like an oil change for your transmission, help optimize performance and longevity of this key system with a visit to Jiffy Lube® for a transmission fluid exchange. Learn more about Transmission Fluid Exchange Jiffy Lube® recommends following manufacturer recommendations, where applicable, for maintenance schedules and service intervals. MANUAL TRANSMISSION SERVICE. Manual transmission lubricant protects gears, bearings, shafts and other internal components. Changing the manual transmission fluid at Jiffy Lube® at the vehicle manufacturer’s recommended interval can help prevent premature wear, damage to the transmission and costly repairs.
