winIDEA Callstack: Issues with display

The Callstack Window doesn't show current call stack content or the displayed info is incorrect.

Possible solutions

Compiler optimization

The compiler can optimize the code to the extent that the required information being used by the debugger to extract the Call Stack context is not available or just not sufficient. Check the compiler manual for any relevant compiler switches and try to decrease compiler optimization level(s) - at least for the test to confirm that this is the root cause for Call Stack not being displayed properly.

Call Stack Generation

Call Stack can be generated using information from different sources: ELF file, CPU EABI, or by code simulation. 

1. Open Debug | Configure Session | Applications | Symbol Files.

2. Select the download file and press Edit.

3. Click Advanced to open the Edit Options dialog.

4. From the drop-down Call Stack Generation field select:

• EABI - Call Stack is generated as specificated in the EABI documentation for specific architecture.
• using .debug_frame - ELF debug_frame section will be used to unwind the stack.
• Simulated - Call Stack is reconstructed by using object-code simulation.
