Creating the Core Dump for Application Failure

This section provides a quick start guide to create the core dump for an application that fails.

The Core Dump Subsystem (CDS) helps the debugging of an application failure or a system failure by creating a core dump, which is later used for analysis.

To create a core dump containing system-wide information in Symbian ELF format, perform the following steps:

  1. Run the application on an H4 board.

  2. Click Tools > Extras and select the coredumpui application to start the TechView-based configuration UI.

  3. Click Lists > Process to view the list of processes that are running.

  4. Select your application process from the list and click Observe to create a core dump when the application fails.

  5. Click Lists > Plugin and load the Symbian ELF Core Dump Formatter plugin and the Symbian File Writer plugin.

  6. Select the Symbian File Writer plugin and click Configure to specify the complete path for the core dump file.

  7. Click Configure to save the path.

This results in creating the core dump when a hardware or thread kill exception is reported for the process being observed. The configuration UI shows the progress while the core dump is being created. After the core dump file is created, you can transfer the file to your PC and analyse it.
