All rights reserved.5 The lab consists of a number of sections with exercises concerning debugging and the goal is to give you a good introduction to IAR Embedded Workbench and the IAR C-SPY debugger for RX. Part 1 – Get up and running by executing an existing sample application on hardware Part 2 – Complex data breakpoints. This exercise will make you familiar with C-SPY’s data breakpoint feature to investigate how and when data changes. Part 3 - Using trace to find bugs. By using trace, you can inspect the program flow up to a specific state, for instance an application crash, and use the trace data to locate the origin of the problem. Lab overview(1/2)

Function profiling can help you find the functions in your source code where the most time is spent during execution and perhaps give insight into how to rewrite it for better performance. Part 5 - Using the performance analysis counter. The performance analysis feature allows you to measure a number of execution aspects in run-time without slowing down your MCU. Part 6 - Introduction to the ThreadX RTOS plugin for C-SPY. The ThreadX plugin for the ThreadX RTOS simplifies debugging of real-time applications with useful multithread-specific features. It adds extra features to the C-SPY debugging interface that are specific for the ThreadX RTOS. Lab Overview (2/2)
