#Nucleo f401re keil debugging PatchIf you are using MDK 4.54 or earlier, a patch is available to enhance the performance of the ST-Link V2. Configuring the ST-Link V2 debug adapter starts on page The on-board ST-Link V2 is used by default in this document. The latest version of this document and the necessary example source files are available here: /appnotes/docs/apnt_230.asp 2. #Nucleo f401re keil debugging how toWatch and Memory windows and how to use them: How to view Local Variables in Watch and Memory windows: View Variables Graphically with the Logic Analyzer (LA): Watchpoints: Conditional Breakpoints RTX_Blinky example: Keil RTX RTOS: RTX Kernel Awareness using RTX Viewer: Logic Analyzer: View variables real-time in a graphical format: ITM (Instruction Trace Macrocell): Serial Wire Viewer (SWV) and how to use it: 16 1) Data Reads and Writes 16 2) Exceptions and Interrupts 17 3) PC Samples (program counter samples) Serial Wire Viewer (SWV) Configuration: DSP Sine Example using ARM CMSIS-DSP Libraries Creating your own project from scratch: ETM Trace and its benefits: for reference Serial Wire Viewer summary: Useful Documents: Keil Products and contact information: 33 Notes on using this document: 1. Blinky example using the STM32F4 Discovery board: 6 7. CMSIS: Cortex Microcontroller Software Interface Standard 3 5. This document uses only the on-board ST-LINK. Keil MDK has examples and labs for these boards. Versions are available with Cortex-M3 and Cortex-M4 processors. In order to use features like ETM trace, it is easier to obtain a board such as the Keil MCBSTM32 series or a STM32xxx-EVAL board. This means it is not easy to connect a ULINK2, ULINKpro or J-Link to these boards. Discovery Board Debug Adapter Connections: The STM32F407 Discovery board lacks the standard ARM debugger connections. Most other ST and Keil boards do have this connector. The Discovery series do not have the ETM connector even though the processor has ETM. ETM requires a special debug adapter such as a ULINKpro. Keil µvision uses ETM to provide Code Coverage, Performance Analysis and code execution times. This is very useful for debugging program flow problems such as going into the weeds and how did I get here?. Embedded Trace Macrocell (ETM): ETM displays all the program counter values that were executed. CoreSight displays memory contents and variable values in real-time and these can be modified on-the-fly. (except for the ITM Debug printf Viewer). SWV does not steal any CPU cycles and is completely non-intrusive. This information comes from the ARM CoreSight debug module integrated into STM32 CPU. Serial Wire Viewer (SWV): Serial Wire Viewer (SWV) displays PC Samples, Exceptions (including interrupts), data reads and writes, ITM (printf), CPU counters and a timestamp. A DSP example program using ARM CMSIS-DSP libraries. RTX Viewer: a kernel awareness program for the Keil RTX RTOS that updates while your program is running. Six Hardware Breakpoints (can be set/unset on-the-fly) and four Watchpoints (also known as Access Breaks). No instrumentation code is added to your source files. Real-time Read and Write to memory locations for Watch, Memory and RTX Tasks windows. Real-time tracing updated while the program is running. This helps you get your project completed faster. Keil Technical Support is included for one year and is easily renewable. Kernel Awareness is available for Keil RTX, CMX, Quadros, Micrium and FreeRTOS. Serial Wire Viewer and ETM trace capability is included. #Nucleo f401re keil debugging fullA full feature Keil RTOS called RTX is included with MDK. µvision IDE with Integrated Debugger, Flash programmer and the ARM Compiler toolchain. Why Use Keil MDK? MDK provides these features particularly suited for Cortex-M users: 1. #Nucleo f401re keil debugging full versionRTX RTOS: All variants of MDK contain the full version of RTX with source code. The addition of a valid license number will turn it into the full commercial version. Nearly all Keil examples will compile within this 32K limit. Keil MDK-Lite is a free evaluation version that limits code size to 32 Kbytes. #Nucleo f401re keil debugging androidCheck the Keil Device Database on /dd for the complete list which is also included in MDK: in μvision, select Project/Select Device for target Linux: ST processors running Linux, Android and bare metal are supported by ARM DS-5. Keil MDK supports and has examples for most ST ARM processors. At the end of this tutorial, you will be able to confidently work with these processors and Keil MDK. We will use the Serial Wire Viewer (SWV) and the on-board ST-Link V2 Debug Adapter. 1 STMicroelectronics: Cortex -M4 Training STM32F407 Discovery evaluation board using ARM Keil MDK Toolkit featuring Serial Wire Viewer Summer 2012 Version 1.1 by Robert Boys, Introduction: For the latest version of this document: /appnotes/docs/apnt_230.asp The purpose of this lab is to introduce you to the STMicroelectronics Cortex -M4 processor using the ARM Keil MDK toolkit featuring the IDE μvision.
