Upgrade/Install instructions

First time install
Please use the provided installer and just follow the steps in order to install Developer Studio for the first time.

Upgrade
Updates are automatically checked at each Developer Studio launch, and it is possible to upgrade to the new version just by following the instructions.
It is also possible to start the updates checking job by using the Help > Check for Updates menu.

Important notes concerning existing workspaces/projects compatibility and upgrade:

• Exported settings handling (since 2.1.1)
  From 2.1.1, Developer Studio uses the built-in CDT mechanisms to handle settings export/import between depending projects.
  A library project shall export the settings to be applied in any application project depending on it (cf. Project Properties > C/C++ General > Exported Settings).
  Library projects created with Developer Studio will automatically benefit from these settings management.
  Projects created with a former Developer Studio version will have to be upgraded to export settings correctly. Please refer to the forum for more information.
  
  
• New project medatada format (since 1.2.0)
  From 1.2.0, Developer Studio uses a new metadata format for handling Open AT projects.
  When reusing an existing workspace which was created with an older version (i.e. 1.1.2 or older), projects are automatically converted to this new format, but won't be compatible anymore with former versions.
  If you plan to still handle projects with former versions, it is recommended to start a fresh new workspace with Developer Studio 2.2.1, and to import the needed projects from the former workspace to the new one.

Note concerning upgrade from 1.1.0 release or older:
If you are currently using Developer Studio version 1.1.0 or older, it is not possible to upgrade it to 2.2.1 release; you have to use the provided Software Installer instead, in order to install it in an empty new directory.

Installation over an Eclipse platform

It is possible to install Developer Studio as a set of plug-ins over an existing Eclipse platform.

• Prerequisites: Developer Studio 2.2.1 requires Eclipse Indigo (3.7.1) version. Download it from http://www.eclipse.org/downloads/packages/release/indigo/sr1
  (Best choice to start is Eclipse for C/C++ Developers)
  Developer Studio plug-ins can be installed on Win32 and Linux (32 or 64 bits) platforms
• Go to Help > Install New Software
• Add the following URL as new update site (drag'n drop the URL to the Eclipse dialog box): http://updatesite.sierrawireless.com/developerStudio
• Make your choice regarding the features you want to be installed on top of your Eclipse:
  * Developer Studio for Eclipse category:
      - Either use the Developer Studio all-in-one feature, which will install all the functionalities and toolchains.
      - Or use the Developer Studio base plugins for just Target Management access, and Open AT Projects Management to have full featured Open AT IDE (without toolchains)
  * Developer Studio: Toolchains category: Choose the toolchain you want to install among the proposed ones.
• Click Install and follow the steps.

Installation of Developer Studio source code (advanced users only)

Developer Studio source code is available for Eclipse developers.

Known limitations & bugs

1. Build system / Open AT Projects management

• Workspace paths with space characters are not supported
• No synchronization check between the Firmware version used in a project, and the one running on the connected Module

2. Target management

• Heap memory status does not contain links to source code
• 7.44 Firmware bug impact (fixed in 7.45 and above): on USB connection, as soon as Development Mode is configured to resist to target reset, AT commands answers are not displayed.
  Workaround: in the preferences, disable the development mode persistence option when working with an USB connection

3. Run & Debug

• 7.45 Firmware bug impact (fixed in 7.46 and above): embedded GDB step by step debugging is not always reliable (e.g. running a step after a breakpoint on a switch statement sometimes doesn't enter in any case).
  Workaround: prefer working by modifying breakpoints position and resuming the execution
• RTE on Windows 64 bits systems: RTE debugging uses a virtual serial port driver named "com0com". This driver is currently not signed, and 64 bits systems refuse to enable it in normal conditions.
  Workaround: com0com driver can be enabled by switching the OS in test mode (cf. com0com readme file for more information)
