🟡 Debug and Trace
Debug and Trace Embedded Systems
Analyze Errors and Unexpected Behavior
Debug and Trace help developers understand how embedded software behaves on the target and investigate problems during development and integration. Developers analyze program flow, locate errors, record runtime behavior, and measure performance and resource consumption. Modern debug and trace tools provide detailed insight into complex real-time systems and support systematic root cause analysis.
A Typical Embedded Debugging Workflow
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
