Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Search existing ideas

Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,

Post your ideas
  1. Post an idea.

  2. Get feedback from the IBM team and other customers to refine your idea.

  3. Follow the idea through the IBM Ideas process.

RSARTE Debug -- GNU MCU C/C++ J-Link Debugging

Somewhat recently RSARTE 2018 become incompatible with respect to debugging RSARTE generated ARM microcontroller projects.

We develop CortexM4/7 firmware using RSARTE. For a long time we could debug and have peripheral registers visible in the debugging session via the GNU MCU C/C++ Eclipse plugins.

Somewhat recently an incompatibility has developed between the C++ source directories RSARTE generates (and in particular the .cproject file therein) and GNU MCU C/C++ J-Link Eclipse plugins so that the processor device type can no longer be selected via the C++ project preferences and as a result the peripheral function registers are no longer visible.

I have found that right before debugging I can replace the .cproject file in the RSARTE generated project with one created with the GNU MCU plugins including the J-Link & Packs plugins installed and the appropriate microcontroller pack selected.

This GNU MCU project is created by Eclipse RSARTE>File>Project...>C/C++>C++ Project/ARM Cross GCC. Then the microcontroller device type in the newly created ARM Cross GCC project is selected by: Eclipse RSARTE>Properties>C/C++ Build>Settings/Devices/...

    As part of the review process, we strive to be transparent about our intentions with each enhancement suggestion. Since the creation time of this ideas the product has evolved and your input may have been incorporated into newer releases.

    Should this be not the case, please feel free to recreate it in our new Idea workspace for DevOps Model and Code RealTime (Please find here a blog how to achieve that:

    The idea will be kept in IBM's ideas repository and may still be voted on. It might be reassessed or reopened for additional feedback in the future. We value your feedback and thank you for allowing us the privilege of partnering with you in developing our products.

    It turns out that one can enable the MCU peripheral registers debugging by
    1. Setting the generated project's properties "C/C++ Build/Tool Chain Editor>Current Toolchain" to "ARM Cross GCC"
    2. Setting the generated project's properties "C/C++ Build/Settings>Devices Tab" to

    No enhancements are needed to RSARTE.
