1. Code Composer Essentials 3.0
Extending CDT and Eclipse
for Embedded Development
Dobrin Alexiev: Texas Instruments

2. Project Launch Workflow
Create new project, write code, compile, debug
Last opened project is called Active
The Launch Dialog is not required
Projects may have debug properties
Creates and reuses Launch Configurations
Similar to other IDEs

3. Projectless Debugging Workflow
Connect to a multi core debugger
Connect to the desired target
Watch or modify memory, registers, disassembly
Load programs or symbols to different CPUs
Now we can see valid call stack and variables
Specify search path
Full source level debugging
Hides the Launch Dialog
Creates and reuses launch configurations

4. Breakpoint additions Add hardware breakpoints support
Add combo box in the Breakpoint View
Add symbolic type breakpoints
Project-less and program-less debugging
Breakpoints are installed after target connect
Symbols can change dynamically

5. Breakpoint challenges
Having Resources for some but not all types
Fixed Hierarchy
Symbolic breakpoints
Hardware breakpoints
Association of breakpoint to targets and threads
A breakpoint can’t be set on multiple targets
What if the breakpoint has different properties on two targets
Install breakpoint after target is connected

6. Breakpoint Alternatives
A breakpoint is a set of properties
No need for hierarchy
All of the functionality is by set and get properties
A server can change the breakpoint properties at any time – function type becomes source type
A Debugger implementation can overlap with code that is in CBreakpointManager
Source editor shows breakpoints based on Current Debug Context
By default breakpoints are not shared by all targets
Each target has its own set of breakpoints

7. More Target States Connected vs. Disconnected Halt Requested
The debugger is up but it doesn’t have a connection to the target
Symbols don’t have to be reloaded on connect
Breakpoint will be reinstalled on connect
Halt Requested
When CPU halts all OS thread are suspended
Only the current thread is really Halted
The rest will resume as soon the CPU runs
The user can request to Halt other threads

8. Multiple Targets and Threads
Launch or Debug Target per CPU?
Can each thread has its own symbols?
Breakpoints per target…

9. Views enhancements Expression view Disassembly view Memory View
Modifiable expressions
Edit enums with a dropdown box
Run and Halt scroll the view
Disassembly view
Scrolling outside of the current function
Address selector dropdown
Opened automatically if limited debug info is available
Memory View
Shows physical vs. virtual memory
Address selector drop down
Breakpoint View
Add new breakpoints from a drop down
Source View
Add breakpoint not only from selection margin

10. GUI Testing Framework Automates the workbench GUI using JUnit tests
Executes menus, toolbar and context menus
IWorkbenchWindow wb = fScripting.getWorkbench();
wb.getMenuAction("File|New|Project...").asyncExecute();
Synchronizes with the GUI elements
getTopMostDialog().waitUntilDialogHasTitle("New Project“)
Select tree nodes, executes buttons, sets text in edit boxes
control.selectNode(“Plug-in Project“)
Provide higher level interface for the Specific Views and Editors
