🟡 Debug and Trace
Phase 2: Debug and Trace - Analyze Errors or unexpected Behavior
Debug and Trace ensure that embedded software not only functions but also operates reliably and efficiently. Developers analyze program flow, locate errors, record runtime behavior, and measure performance and resource consumption. Modern debug and trace tools make even complex real-time systems transparent and enable rapid root cause analysis.
In a typical Embedded Project, these Steps are followed:
1️⃣
Load Firmware onto the Target Hardware
- Flash the current software version
- Establish a connection to the debugger (e.g., J-Link)
- Start the debug session
2️⃣
Analyze Program Execution
- Set breakpoints and step through the code
- Monitor variables, registers, and memory
- Trace the call stack and program flow
3️⃣
Locate Errors
- Determine the causes of crashes, hard faults, or exceptions
- Detect initialization and timing errors
- Investigate race conditions and synchronization issues
4️⃣
Record Runtime Behavior (Trace)
- Record program execution without pausing the system
- Analyze task switches, interrupts, and events
- Visualize time-critical sequences
5️⃣
Measure Performance
- Determine function execution times
- Analyze CPU utilization and task runtimes
- Monitor memory and stack usage
6️⃣
Derive Optimizations
- Identify bottlenecks
- Improve real-time behavior
- Optimize memory usage and runtime
- Fix bugs and re-verify changes
