    Known limitations & bugs


    • Needs an external Java environment previously installed (JAVA 1.6) when using the installer. Once installed, M2M Studio is standalone

    Build system / Open AT Projects management

    • Linker settings are corrupted when importing a project created with M2M Studio 1.0.0
    • Workspace paths with space characters are not supported
    • No synchronization check between the Open AT Firmware version used in a project, and the one running on the connected Wireless CPU

    Target management

    • M2M Studio sometimes crash suddenly on operations related to Target management (connect, baudrate autodetection, download)
      Seems to be related to USB-Serial converter usage
    • Backtraces decoding is not supported
    • Heap memory status does not contain links to source code
    • Trace logging is disabled as soon as the target resets
    • Baudrate autodetection is not configurable
    • Target info view is not automatically refreshed

    Run & Debug

    • JTAG Debug relies on third-party non-integrated software (Open OCD)
    • JTAG Debug works only is the download step is skipped in the Run configuration
    • No check if the connected Wireless CPU is "JTAG-able"
    • Breakpoints cannot be added during a debug session while the program is running (they have to be added when the execution has stopped on another breakpoint)

    Bugs fixed


    Install / General

    • Issues fixed regarding install/uninstall of some packages

    Build system / Open AT Projects management

    • Popup error messages when project package dependencies are missing have been replaced by error markers in the Problems view

    • ATI9 info was not always updated when modifying project dependencies
    • Sometimes, "An internal error occurred during: "C/C++ Indexer" message war appearing at project creation/import.
    • Library projects dependencies are now managed automatically
    • It is now possible to import a project created under a Windows M2M Studio into a Linux M2M Studio

    • ARM ELF GCC / MinGW build was failing if path to SPM Registry is too long (>~100 characters, ie. workspace path >~50 characters with default settings)
      Now embedded compilers are managed in M2M Studio install location, and a warning is displayed in M2M Studio preferences if the install path is too long.

    Target management

    • Debug traces logging to file feature was not usable ("cyclic buffer" behavior, beginning of the file was lost after some time)

    Build system / Open AT Projects management

    • No need anymore to take care about the libraries order on the ARM ELF GCC linker command line
    • Some plug-ins samples (e.g. from C-GPS plug-in) dependencies to other plug-ins not correctly managed
    • It was not possible to change the current OS version in a library project
    • Bad symbol name generation for C-GPS plug-in (makes the build fail with ARM compilers)
    • Incremental build was not working (relink of the application was performed on each build request)
    • Added by default the -fno-profile option on ARM ELF GCC compiler command line
    • IDE V1 project import was not working when source paths out of the project directory were referenced
